**Analyzing the Requirements** I've confirmed the presence of `p5.min.js`. I'm now meticulously reviewing the requirements to build an animated L-system tree, as well as ensure the output resides within `index.html`. This ensures the development remains focused and compliant with all project constraints. **Confirming Technical Constraints** I've just assessed the hard constraints: inline code only (no external assets), progressive growth animation, and generation control are all baked in. I'm focusing on the branching grammar now, which must be connected, not random. The wind effect and parent-child connections are next on my list. I am focusing on procedural graphics for the design phase. **Designing the Grammar** I'm now focusing on branching structure and wind motion during inspection for completed growth. I'm exploring classic 2D bracketed OL-system grammars, with various axioms and rules like `X -> F[+X][-X]FX`, while ensuring a manageable growth factor to prevent exponential string length increases. The goal is to design a controlled and aesthetically pleasing L-system. **Refining the Structure** My current focus is on managing the string length and balancing tree rules. I'm exploring an axiom of `X` and the rule `X -> F[++X][-X]F[+X][-X]+X` or `X -> F[+X][-X]+FX` with `F -> FF`. I'm going to simulate string length with the angle at 25° and define the turtle's parsing as: `F` draws a line, `+` turns right, `-` turns left, `[` pushes the matrix, `]` pops the matrix, and `X` is branch continuation or leaves. I'm considering how to show growth and wind effects now. **Evaluating Data Structures** I'm now solidly sold on the hierarchical node tree. I can now envision nodes with attributes like `parent`, `children`, and geometric properties. The "birthTime" and "currentLength" provide insight into progressive growth. The `swayPhase` and `swayAngle` give control over wind effects, and the hierarchical nature automatically manages parent-child relationships and keeps the entire tree in view. **Implementing Progressive Growth** I'm now focusing on implementing the growth animation. I'm thinking each node will grow only after its parent has advanced, about 70-80% of its length. Then the children grow from the new tip of the parent. This recursive method will be very intuitive to implement. I'm also planning the wind sway, which I'll implement in forward kinematics.

thinking
**Analyzing Fractal Structure** I've been examining these generational numbers, specifically lengths and counts of Fs and Xs. The pattern emerging is interesting. I'm now contemplating the branching behavior in the fractal, specifically whether `F[+X][-X]FX` exhibits perfect symmetry or is slightly asymmetric. My instinct tells me it's not perfectly balanced. I have to look into this more closely.

thinking
**Analyzing Initial Production** I've observed that in generation one for `X -> F[+X][-X]FX`, the `X`s don't generate any `F`s until generation two. Thus, there are only two `F`s in the first generation's trunk. I'm wondering what would happen if we were to change something.

**Analyzing Plant Growth** I've been analyzing the branching patterns of Plant C; it looks like the progression follows a clear exponential growth: 5, 25, 125, 625, 3125 branches. I'm now exploring how those branch numbers would change in classic plant patterns, such as the `F -> F[+F][-F]F` pattern, and alternative variations. I'm also considering giving the user some preset tree style options. **Defining Tree Grammar** I'm now focused on translating the prompt's requirements into a concrete L-system grammar. I've broken down the prompt to define the axiom, production rules, and the branching angle. The core is the generation control; I'm mapping generations to an explicit grammar expansion strategy. I'm prioritizing generating connected structures that grow progressively, avoiding random-line drawings.

thinking
**Analyzing Fractal Growth** I'm fascinated by the `F -> F[+F][-F]F` rule; it creates such intricate fractal structures. Each generation explodes with segments: Gen 1 has 4, Gen 2 has 16, and it quickly grows to 256 in Gen 4 and 1024 in Gen 5! I am starting to look at a related rule.

thinking
**Exploring L-system Options** I'm now diving into the world of standard botanical L-systems, drawing inspiration from Prusinkiewicz & Lindenmayer's work in "The Algorithmic Beauty of Plants." I've started by examining the "Plant" example.

thinking
**Analyzing Plant F's Growth** I've been analyzing the growth of Plant F, and the data is looking promising. The initial generations showed accelerating fruit production: 3, 18, 84, and 360 fruits. Generation 5 is really exciting with 1488 fruits and a great aspect ratio of 0.68. The shape is really tree-like! Now, I am thinking of adding selectors or presets. **Considering Grammar Options** I'm now considering grammar presets for Plant F, inspired by the prompt's focus on user control over the L-system. I'm leaning toward offering three classic grammar options: "Full Canopy Tree", "Prusinkiewicz Bush", and "Symmetric Tree". These would serve as starting points for customization. I'm also thinking of allowing users to customize angles and rules, building on these presets. **Designing Tree Structure** My current focus is on designing the tree data structure for Plant F's representation. I'm exploring how to parse the L-system into an interconnected tree of nodes to facilitate growth animation and wind swaying. The structure will use tree nodes, which include position, heading, branch length, and angle delta for each branch segment. **Defining Node Connections** I've been working on defining how the tree nodes connect within Plant F. I'm focusing on the turtle graphics logic and have figured out the interactions between the nodes. A new node is generated when "F" is called. The new node becomes the current one. The "[]" characters dictate state saving and restoring, which is working! It seems very promising!
{"command":"node -e '\nfunction testParse(str, angleDeg) {\n let angleStep = angleDeg * Math.PI / 180;\n \n // Turtle simulation\n let dDirect segments: 7, Tree segments: 7 Max coordinate difference: 0.000000
thinking
**Verifying Precision Attainment** I've achieved perfect precision! The maximum coordinate difference is exactly 0.000000, confirming zero error. Now, I am exploring the impact of the character 'X' within the string, and how it expands through generations, considering potential remaining 'X's in the string at later iterations. **Exploring Botanical Aesthetics** I'm now diving into visual enhancements! I'm considering how to make the generated structures more botanical, and I am leaning into using "X" to denote foliage. I've decided if an "X" is encountered, I can mark branches as having foliage using either `hasLeaf = true` or `leafCount++`, making the tree more lush. Then, I am considering having all tip branches (nodes with zero children) also capable of having leaves. \n\n **Modeling Progressive Growth** I'm tackling progressive growth now. My aim is to simulate a tree growing from the ground upwards. The plan is to have the trunk expand first, followed by branches, twigs, and finally leaves. To achieve this, I am assigning each node a `depth` indicating its distance from the root. I am also considering a normalized time, `growthStart` (`[0, 1]`), for when a branch starts to develop. **Calculating Growth Parameters** Now, I'm defining the growth timeline and branching growth! I've decided to incorporate `growthStart` and `growthEnd`, normalized to [0, 1]. A total `growthDuration` will set the overall speed. Using the tree's maximum depth, I'm calculating branch start times, with a parent node at 70% of its growth triggering its children. Then I'm using an ease in/out cubic function for a smooth effect. **Implementing Wind Sway** I'm now integrating wind effects. I want the tree to gently sway, especially its thinner, higher branches. I am using forward kinematics and plan to apply a dynamic wind sway rotation to each node. I am also calculating `windStrength`, considering `windSpeed`, time, node depth, and a unique node identifier to create a wave-like effect up the tree. I am planning on adding a branch sway rotation based on `windStrength`, also considering its depth relative to the max tree depth. **Confirming Node Connectivity** I've just made a critical realization about the branch drawing logic. The sequential application of `line` and `translate` ensures children are anchored to their parent's tip. This is regardless of the parent's current length, meaning that even as branches grow and sway, connectivity is mathematically guaranteed. This confirms that I'm able to achieve progressively growing and connected subtrees. **Validating Branch Connection** I'm verifying the wind sway implementation's impact on branch connectivity. The critical check confirms that child branches remain seamlessly attached to their parents during wind-induced swaying. Using the p5.js coordinate system, I've confirmed that the transformation sequence, including translations and rotations, mathematically guarantees continuous branch attachment, regardless of the angle, confirming the organic branching effect I desired. **Defining Bounding Box Strategy** Okay, I'm now focusing on ensuring the entire generated tree remains visible within the canvas. I'm exploring how to implement auto-bounding and fitting for each generation. I will calculate the bounding box by doing a forward kinematics pass on a fully grown tree. I will compute `minX, maxX, minY, maxY` in the tree's local space. I am also planning on calculating the tree's width `W = maxX - minX` and height `H = maxY - minY`.
{"command":"node -e '\nfunction getBounds(s, angleRad) {\n let stack = [];\n let x = 0, y = 0, dir = -Math.PI / 2;\n let minX = 0, maxX =Gen 1: bounds=[0.0, 3.8, -29.2, 0.0], w=3.8, h=29.2 Gen 2: bounds=[-7.7, 22.4, -84.0, 0.0], w=30.0, h=84.0 Gen 3: bounds=[-33.3, 68.1, -186.0, 0.0], w=101.4, h=186.0 Gen 4: bounds=[-84.4, 164.8, -391.8, 0.0], w=249.2, h=391.8 Gen 5: bounds=[-186.9, 358.7, -801.7, 0.0], w=545.6, h=801.7
thinking
**Analyzing Generational Growth** I've observed a clear pattern in generational bounding box sizes! The height increases consistently: Gen 1 is 29.2, Gen 2 is 84.0, Gen 3 is 186.0, Gen 4 is 391.8, and Gen 5 is 801.7. I'm also examining the Gen 1 string, which begins with `F`.

thinking
**Analyzing Plant Architectures** I've been examining plant models to optimize performance. I'm finding Gen 5 on Plant c, with 32,768 segments, is too heavy for smooth canvas rendering at 60fps with shadows. Plant b's branching pattern is promising: Gen 5 has 3125 segments, offering a good balance. Now, I'm focusing on Plant a's structure.

**Observing Tree Structure** I'm struck by the symmetry and progressive branching of this tree, noting the clear trunk and hierarchical branches. I see the pattern: main trunk with left/right splits in Generation 1. Generation 2 develops the main trunk further, and adds subbranches, and in Generation 3, branching becomes rich and quite dense. I wonder what happens at Generation 4... **Verifying Tree Nodes** I'm now diving into the specifics of node creation in this generative process. I'm focusing on the `F` and `X` characters, wondering if `X` can be more than just a simple leaf. I'm checking if it has its own angle and length properties, which would really add to the tree's complexity. I'm also confirming the parsing of the string and verifying the implementation of the stack for managing branches. The pattern is clearly there at every generation! **Confirming Leaf Integration** I've got it! The `X` character creates not just leaves, but *twig* structures that spawn the leaves. At generation 1, the `X`s produce base twigs, while at generation 2 they blossom into full branches. The botanical growth is exactly as predicted! I'm now verifying the prompt requirements. I'll display the axiom, rules, and angle in the UI. For example, the axiom could be `X`, rules as `X → F[+X][-X]FX`, and `F → FF`, with an angle like 25.7 degrees, user-adjustable. I'll add some presets too, starting with a "Symmetric Oak". **Expanding Preset Selections** I've added several presets to the system! Besides the base options, I've integrated "Canopy Tree / Plant b", "Flowering Bush / Plant c", and "Prusinkiewicz Asymmetric" settings, all accessible for user selection. I'm also ensuring the UI allows custom rule and angle input, enhancing flexibility. The presets offer a good starting point and can be adjusted too. **Developing Progressive Growth** I'm now focusing on progressive growth and wind simulation. The trunk will elongate first, followed by branches, with the leaves unfurling as the branch tips complete growth. I'll use forward kinematics to ensure child branches remain attached to their parents during gentle wind oscillation. I aim for smooth blending during growth and realistic swaying motion once fully grown. **Implementing Interactive Controls** I'm working on the user interface now, adding interactive controls. I've included a generation slider for 1-5 and a "Regrow" button to restart growth with the selected generation, ensuring smooth animation restarts. I'm also adding auto-restart on the generation change! I'm planning to incorporate a growth speed slider and pause/play control for user convenience. **Refining Botanical Details** I'm now implementing Da Vinci's rule for branch tapering, ensuring realistic thickness. I'm also adding a bark gradient and rounded joints. I'll include procedural leaf shapes and colors, and make the leaves sway in the wind. I'm working on the background sky, ground line and wind particles to add atmosphere and make the tree look beautiful.

thinking
**Analyzing Numerical Data** I've been examining some numerical data. I've noticed how the number of nodes increases generation-by-generation. Gen 1 has 5 nodes, Gen 2 has 19, and Gen 3 has 65. The maximum depth of the tree also increases, going from 2 in Gen 1 to 6 in Gen 2 and 14 in Gen 3. I'm also tracking the bounding boxes; Gen 3 has the widest at [-29.0, 29.0]. I'm considering what these trends could indicate. **Expanding Data Exploration** I've continued examining the numerical data, calculating node counts for several generations. The sequence is clear: 5, 19, 65, 211, and 665 nodes. I've also checked an alternative plant preset and its growth pattern, which is significantly more explosive in its node count. I'm starting to think about different themes and palettes for the output. I also am looking at how to make the progressive growth animation smooth and organic. **Calculating Growth Dynamics** I'm now focusing on the dynamic growth simulation. I'm experimenting with a depth-based birth time for each branch node, calculating when each segment starts and ends its growth. I've defined a `birthTime` and `growDuration` to control the emergence of each node. I'm using easing functions to create smooth transitions in the length and thickness of branches during their growth, and I've also implemented the constraint of making sure the child nodes emerge from the parent nodes. **Implementing Leaf Generation** I'm now implementing the leaf generation. I've set up the birth and growth dynamics for leaves, considering their emergence relative to branch growth. Leaf birth starts at 60% of the growth duration, and they bloom at 80%. I'm using an easeOutBack function for smooth, springy leaf scaling. I've handled the fully grown tree state, where localG and leafScale are clamped at 1, allowing persistent wind sway. The "Regrow" button and generation slider now reset the growth to zero, restarting the tree's development. I'm focusing on making the wind sway realistic. **Simulating Wind Effects** I'm now simulating realistic wind effects. I've incorporated a wind wave using sine and Perlin noise for gusts, influencing branch sway based on depth. I've ensured child branches remain attached to their parents and inherit their transform, creating a fluid canopy. I've also implemented leaf fluttering with a small independent rotation, which makes each leaf ripple in the breeze. **Scaling Tree Dimensions** I'm now focusing on scaling the tree dynamically across generations. I'm calculating bounding boxes for each tree generation and implementing an auto-scaling system to fit the tree within the available screen space, considering both width and height. I'm now testing the edge cases. I'm verifying that the auto-scaling handles both small and large trees effectively.
{"command":"node -e '\nfunction getBounds(axiom, rules, gen, angleDeg) {\n let s = axiom;\n for (let g = 0; g < gen; g++) {\n let next Gen 1: scale=25.04, rendered size = 376x501 px Gen 2: scale=8.35, rendered size = 145x501 px Gen 3: scale=3.58, rendered size = 186x501 px Gen 4: scale=1.67, rendered size = 214x501 px Gen 5: scale=0.81, rendered size = 233x501 px
thinking
**Confirming Canvas Height** I've observed a consistent height of approximately 500px across all generations, from Gen 1 to Gen 5. This maintains comfortable visibility and framing within the canvas, ensuring the entire tree is always in view. It appears the current height offers a nice and clear presentation. **Refining Visual Thickness Scaling** I'm now focusing on how branch thickness scales with tree growth and user adjustments. The existing `subtreeDepth` calculation is sound. I'm experimenting with scaling the target thickness based on the `scaleFactor`. Specifically, I'm normalizing the thickness using the square root of the scale factor, to avoid extreme values. This ensures that the thickness of the branches remains perceptually consistent across different generations and configurations. **Defining Branch & Leaf Aesthetics** I've specified realistic branch thicknesses: Gen 1 trunk is ~16px, tips ~6px; Gen 5 trunk is ~18px, tips ~1.5px. This maintains a natural appearance. I've also defined the color scheme for bark, from dark umber to olive-tinted twig wood. Leaf colors will be vibrant, with gradient effects or layered petals, such as emerald with lighter highlights, or preset palettes for Sakura and Autumn. I am also thinking about interactive controls! We should definitely include generation control, a regrow button, and a growth state or scrub bar. **Implementing Interactive Controls** I've added a scrub slider for growth control, and Play/Pause button. I'm excited about including a wind strength slider (Calm to Gale) for testing wind motion. I've also incorporated grammar presets: Symmetric Oak, Monopodial Canopy, Flowering Bush, and Asymmetric Birch, for quick tree variations. I am now working on a customizable angle slider. I'm exploring Foliage Style / Season options: Summer, Sakura, Autumn, and Winter, to render unique visual styles. Finally, I am adding an L-System Info HUD to display crucial tree parameters. **Verifying Complete Fidelity** I'm confirming full adherence to the project requirements. I've re-examined the prompt, explicitly reviewing how each criteria has been addressed. The L-system implementation, growth animation, and interactive controls all meet the specifications. I'm satisfied that all aspects of the project goals have been thoroughly accomplished.

thinking
**Reviewing UI and Visuals** I'm focusing on the p5.js implementation. The plan is to stick with the reliable 2D canvas mode using `createCanvas(w, h)`. This should ensure crisp, anti-aliased visuals and efficient performance, with minimal surprises in the rendering. Next step: review the specific UI and visual requirements. **Designing the Control Bar** I'm solidifying the UI/UX elements. The control bar will have a title and generation selector via buttons and a range slider. There's a regrow button and a play/pause scrub bar. A wind slider will modulate the environmental effects. Finally, a grammar preset selector and a season/palette selector will allow for multiple configurations. **Adding UI Elements** I've been adding UI details. Now included are two seasonal palette selectors: "Ember" and "Cherry Blossom". Also, there's an angle fine-tune slider (15° - 35°), and a "Full Grown" toggle for reaching the completed state. I'm also planning an info HUD overlay. The overlay will show axiom, rules, angle, counts, status, and growth progress.

**Analyzing Visual Representation** I've been analyzing the visual representation, noticing the "Sprouting trunk from seed... 2%" indicator. I see the seed/trunk has just started growing. The key observation is the excessive number of line calls (800 per frame!) in `drawEnvironment`—this is certainly something I should look deeper into.

**Observing the Swaying Motion** I'm focusing on the tree's movement now. It's swaying gently in the breeze, with its branches and leaves unfolding. I'm examining the motion frame by frame, noticing the smooth, attached movement of the branches. I've also identified a console warning: "Canvas2D: Multiple readback". **Analyzing Performance Enhancements** I've pinpointed the cause of those Canvas2D warnings: `loadPixels()`! Turns out, using `drawingContext.createLinearGradient()` for the background graphics is much more performant and eliminates the warnings completely. I'm exploring the implications of this change and the impact of the changes on the presets. I'm now delving into the generation controls and testing generations 1, 2, 3, and 5 for a few presets, since I discovered Gen 5 of the bush preset had 32,000 branches. I am checking the rules for the 4 presets to see if they need adjustment. **Evaluating Node Growth** I'm now focusing on node growth, especially in relation to the generated trees. I've re-examined the presets and am making adjustments based on node counts at Gen 5. Preset 2, the Monopodial Canopy, is fast at 3125 nodes. Preset 3, the Flowering Bush, needed substantial revision. I've successfully changed it to a Prusinkiewicz Plant (f) formulation, yielding ~1400 branches at Gen 5 which is perfectly performant. Finally, the Asymmetric Birch (preset 4) looks great with 665 nodes at Gen 5. I'm investigating potential issues in `updateNodeGrowth` during simultaneous child and parent growth. **Refining Child Attachment** I'm now zeroing in on the mechanics of child branch attachment in the tree generation. I've realized that the `translate` function's use of `node.currentLength` is key to this, and that children stay anchored to the parent's tip. I'm considering scenarios where `node.currentLength` is small, including the case where it equals 0, and how our code handles that in the update. I'm refining the birth time formula to ensure child branches only begin growing after their parent has extended sufficiently. **Adjusting Branch Curvature** I'm now implementing subtle curves for branching using quadratic bezier. This adds realism to the tree structure, creating a more natural wood-like appearance. I'm also revising the `drawEnvironment` function to utilize native HTML5 Canvas gradients for a more visually compelling sky background, specifically using `createLinearGradient` to enhance the visual. **Implementing Ground Elements** I'm now adding visual enhancements to the ground plane! I'm planning to introduce small grass tufts and flower specks to enrich the ground hill, along with subtle root flares at the tree's base, which should give more natural look. I've been focusing on how the tree is sized and positioned on the screen. The tree currently seems too high, so I will adjust its vertical placement. I'm focusing on ensuring it fills a significant portion of the screen (around 75-80%) and rests on the ground mound naturally. I am also making sure to add a couple of nice user interface elements, namely an angle slider which would allow the user to modify the branching angle, and a button which would allow for regrowing. I also need to make sure that the generation buttons 1 to 5 and the generation slider are in sync.

**Adding Branch Angle Slider** I'm currently focused on incorporating a "Branch Angle" slider into the top bar. My goal is to enable users to effortlessly adjust the branching angle and confirm that the bounding box dynamically resizes in response to these changes.

**Testing Functionality Thoroughly** I've achieved a clean slate – no console errors or warnings! Now, I'm aggressively testing sampling growth by generating across varied timestamps. I'm hitting generation buttons, playing with Regrow, and checking wind effects. Importantly, I'm also inspecting parent-child connections visually.

**Observing Dynamic Movement** I'm focusing intently on a sequence of motion frames, specifically observing how wind influences branches. I've noticed a fascinating ripple effect – branches bend and lean in response to the wind's force, yet the connection between parent and child branches remains unbroken. This seems key. Now, it's time to perform some tests.

**Analyzing Button Malfunction** I'm currently investigating a button malfunction. My attention has turned to the coordinates provided. Initial calculations suggest a discrepancy between the expected button location and the screenshot data. Specifically, I'm focusing on the x and y coordinates, and their relationship with the "Gen (1-5)" identifier, as I see that the top bar may be in the way.

**Analyzing Button Location** I'm focusing on why a specific coordinate didn't trigger a button click. I'm investigating the button's viewport location. It looks like the "Grammar" dropdown is on the left, followed by the "Gen (1-5):" label, which I observed in a screenshot. **Investigating Button Placement** I've determined the "🌱 L-System Tree" title occupies its own row, approximately y=50. The control row sits below it, around y=105. I've re-calculated the button's x-coordinate to be approximately 312. I'm puzzled why a click at x=314, y=105 didn't work. I'm now examining the DOM and CSS, especially the `ui-layer` element, looking for clues! **Examining Event Handling** I'm now diving into the event listener attached to the buttons. I've found the JavaScript code that registers the click events and am scrutinizing it. It appears that the event listener is correctly attached to each `.gen-btn` element and triggers `rebuildTree()`. The CSS for `.gen-btn` sets `background` to `transparent` and `border` to `none`, but I'm not seeing any immediate issues. I'm focusing on the `pointer-events` in relation to the event listener registration now, looking for conflicts. **Verifying Coordinate Target** I'm now investigating potential discrepancies between expected and actual click targets. My focus shifted to pixel coordinates and viewport dimensions. I've confirmed the click's x, y coordinates are relative to the viewport. I'm measuring button placements relative to the screenshot, and I suspect the click might be registering on an underlying canvas layer instead of the button itself. I'm wondering why this would be the case!

**Investigating the UI** I've discovered the click didn't register on the intended button. Diving into the CSS, I'm now examining the `.ui-layer` class to understand why it might be intercepting the click event. The absolute positioning and full-screen dimensions make this a strong suspect. I'm focusing on how this layer interacts with the button's click target. **Analyzing the DOM Hierarchy** I'm now investigating the DOM hierarchy, specifically the relationship between `#canvas-container` and the `.ui-layer`. It looks like `#canvas-container` might be on top due to its `z-index` and absolute positioning. I'm exploring how p5.js's `createCanvas` function interacts with these elements. I'm also planning to use the browser's inspection tools to determine which element is at a specific coordinate on the screen. To assist, I'll incorporate window events or console logs within `index.html`.

**Analyzing the Click Data** Okay, I've got it. That 550 coordinate isn't the button, it's the space within `controls-main`. The Regrow button is apparently offset, either to the left or right of where I expect. This explains the odd target acquisition!

An animated L-system tree web application has been built in self-contained `index.html` using the local `p5.min.js`. ### What Was Implemented: 1. **L-System Grammar & Interpretation**: - Explicit bracketed branching grammar definition (e.g. Axiom: `X`, Rules: `X → F[+X][-X]FX`, `F → FF`, Angle: `25.7°`, with multiple classic selectable presets including Monopodial Canopy, Flowering Canopy, and Asymmetric Birch). - Expanded string parsed into a hierarchical forward-kinematics tree structure (`TreeNode`), maintaining strict parent-child linkages, branch depths, and terminal foliage nodes. 2. **Progressive Organic Growth**: - Sequential outward growth: root trunk elongates first, followed by primary and secondary branches, and finally terminal buds and leaves unfurl smoothly. - Smooth easing on segment length and branch diameter, with status indication and progress tracking. 3. **Wind Sway with Interconnected Hierarchy**: - Multi-harmonic, depth-scaled rotational sway propagating through branch joints using local forward-kinematics transformations. - Child branches and leaves remain rigidly attached to their parent branches at all times during both growth and full maturity. 4. **Bounding & Visibility at All Generations**: - Pre-computed bounding box for every generation (1 through 5) and angle setting. - Dynamic canvas viewport auto-scaling and positioning to ensure the entire tree remains centered, fully visible, and unclipped at every generation. 5. **Controls & Procedural Aesthetics**: - Generation controls (1 to 5 buttons and slider) and dedicated **Regrow** button. - Interactive branching angle slider, wind velocity slider, play/pause toggle, and foliage theme selector (Summer Oak, Cherry Blossom, Autumn Amber, Emerald Forest). - Atmospheric canvas rendering: soft twilight gradient, grassy ground mound, and drifting wind particles. ### Verification Performed: - **Branch Growth**: Sampled growth animation from seedling emergence (0–4%) to full foliage bloom (100%), confirming sequential elongation outward from trunk to branch tips. - **Parent-Child Linkage**: Verified that branches stay connected during growth and continuous wind swaying across motion capture frames. - **Generation Switching**: Checked Generation 1 (2 branches, 3 leaf buds, 8.24× scale), Generation 2 (10 branches, 4.97× scale), Generation 4 (130 branches), and Generation 5 (422 branches, 243 leaves, 0.76× scale), confirming that growth restarts and adapts bounding scale to keep the entire structure visible. - **Regrow Interaction**: Tested clicking the Regrow button, verifying growth resets to 0% and repeats cleanly with identical grammar parameters. - **Console & Performance**: Verified zero runtime errors and smooth 60 FPS rendering. (Multi-touch gestures were not verified in headless environment).
