 - [ ] **Task #62: Physics Engine Enhancements (PBD & Rotation)**:
     - [ ] **Task #62.1: Quaternion Rotation**: Implement quaternion-based rotation for `Object3D` and incorporate angular momentum into physics.
     - [ ] **Task #62.2: Position Based Dynamics (PBD)**: Refactor solver to re-evaluate velocity after resolving all collisions and constraints.
-- [ ] **Task #63: Refactor large files**: Split `src/3d/renderer.cc` (currently > 500 lines) into sub-functionalities.
+- [ ] **Task #63: Refactor large files**: Split `src/gpu/gpu.cc`, `src/3d/visual_debug.cc` and `src/gpu/effect.cc` into sub-functionalities. (`src/3d/renderer.cc` was also over 500 lines and was taken care of in the past)
