Conversation
- Implement `THREE.InstancedMesh` in `MicrotubuleTorus` to reduce draw calls.
- Use `useMemo` for `THREE.Object3D` to handle matrix updates efficiently in `useFrame`.
- Add `key={count}` to ensure proper re-initialization when instance count changes.
- Set `frustumCulled={false}` to prevent flickering during animations.
- Reduction from ~1082 to ~4 theoretical draw calls.

💡 What:
Replaced the individual mesh rendering logic in the
MicrotubuleToruscomponent withTHREE.InstancedMesh. The component now uses a single instanced mesh to render all cubes in the torus, updating their matrices in theuseFrameloop using a reusableTHREE.Object3D.🎯 Why:
Rendering hundreds of individual
meshcomponents (360 for the first torus, 720 for the second) created a significant performance bottleneck due to excessive draw calls. UsingInstancedMeshconsolidates these into a single draw call per component, drastically improving rendering efficiency.📊 Measured Improvement:
