**Implementing Raycasting**

I'm focused on implementing raycasting to detect which face of the Rubik's Cube a user clicks. This involves translating mouse coordinates into a ray from the camera to intersect with the cube's geometry.

**Rotating Cube Faces**

I am now actively implementing the logic for rotating individual faces of the Rubik's Cube. This involves collecting the relevant mini-cubes, animating their rotation, and updating their positions after the turn.

**Animating Rotations**

My current focus is on animating the 90-degree rotations of the cube faces. This involves using `requestAnimationFrame` to smoothly transition the affected mini-cubes into their new positions over a short duration.

**Grouping Mini-Cubes**

I am currently grouping the mini-cubes that constitute a specific face for rotation. This temporary grouping allows for easier application of the rotational transformation before re-integrating them into the main cube structure.

I am now meticulously re-examining the logic that determines rotation direction based on clicked face normals to ensure it aligns precisely with intuitive clockwise turns for each face.

**Revising Rotation Logic**

I've thoroughly reviewed the code and confirmed all core functionalities are present. My current focus is on precisely refining the logic that dictates rotation direction, ensuring it aligns with intuitive clockwise turns when a face normal is identified. I am also investigating the potential need for `THREE.SceneUtils.attach` and preparing an alternative approach if it's unavailable.

**Refining Rotation Logic**

This involves carefully updating local transforms when objects move between groups, ensuring their world positions are maintained and the code runs sandboxed. I've also confirmed all core functionalities remain intact.

**Refining Scene Management**

I'm working on updating `processRotationQueue` in `index.html`. My current focus is on replacing `THREE.SceneUtils.attach` with a direct re-parenting method to ensure compatibility with the core three.min.js library. This should streamline scene manipulation.

**Implementing Manual Re-Parenting**

I'm shifting away from `THREE.SceneUtils.attach` in `processRotationQueue`. My focus is on manually detaching and re-attaching mini-cubes between `tempGroup` and `cubeGroup` for improved core `three.min.js` compatibility. I've also identified a minor bug in `onPointerDown` concerning rotation direction calculation.

**Updating Scene Attachment Logic**

I'm now focusing on implementing manual scene object re-parenting within `processRotationQueue`. This involves detaching mini-cubes from their current parent and re-attaching them to the correct group after animation, bypassing `THREE.SceneUtils.attach` for better core library compatibility. I've also noted a potential inconsistency in `onPointerDown`'s rotation direction calculation.

**Refining Rotation Logic**

I'm currently investigating a potential bug concerning rotation direction and the `onPointerDown` functionality. The existing comment about "Direction adjustment" within the `rotateAmount` calculation needs further clarification and potential refinement.

**Clarifying Rotation Mechanics**

I'm currently delving into the `onPointerDown` logic, specifically scrutinizing the "Direction adjustment" comment within the `rotateAmount` calculation. My focus is on ensuring the rotation direction is consistently accurate for all face normals and intended user interactions, like intuitive clockwise turns.

**Revising Rotation Signatures**

I'm re-evaluating the directional logic within the `onPointerDown` handler, specifically how `rotateAmount` is signed based on `clickedFaceNormal`. It appears there's an inconsistency, particularly with Y-axis rotations, where clockwise movement on the top face should correlate to a positive Y-axis rotation. My previous conditional logic may need adjustment to ensure all intuitive clockwise rotations map correctly.

**Correcting Rotation Direction**

I've identified and am now fixing an inconsistency in the Y-axis rotation logic within the `onPointerDown` handler. My current adjustment ensures that intuitive clockwise rotations on the top and bottom faces now correspond to the correct positive or negative rotation around the Y-axis.

**Refining Scene Attachment**

I've updated the HTML to remove `THREE.SceneUtils.attach`, opting for direct re-parenting to maintain core Three.js compatibility. Additionally, I've corrected the Rubik's Cube Y-axis rotation to the expected direction.

**Finalizing Cube Logic**

I've finalized the Rubik's Cube logic, implementing direct re-parenting instead of `THREE.SceneUtils.attach` for better core Three.js compatibility. The Y-axis rotation has also been corrected to match standard Rubik's Cube conventions.
