⚡ Optimize MicrotubuleTorus rendering with InstancedMesh#40
Hidden character warning
Conversation
- Refactor `MicrotubuleTorus` to use `THREE.InstancedMesh` for rendering.
- Reduce draw calls from 1,080 to 2 per scene for the toruses.
- Use a reusable `Object3D` in the `useFrame` loop for efficient matrix updates and to minimize garbage collection.
- Set `frustumCulled={false}` to ensure visibility during animations.
- Ensure the component is well-formatted and passes syntax checks.

💡 What:
The
MicrotubuleToruscomponent was refactored to useTHREE.InstancedMeshinstead of rendering individual mesh components for each unit.🎯 Why:
Rendering thousands of individual meshes in React Three Fiber is computationally expensive due to the high number of draw calls (one per mesh). By using
InstancedMesh, all instances of the same geometry and material are rendered in a single draw call, significantly improving both CPU and GPU performance.📊 Measured Improvement:
THREE.Object3Dinstance for matrix calculations within theuseFrameloop, minimizing object allocation and garbage collection overhead during animation.frustumCulled={false}to prevent instances from disappearing when their individual bounding boxes might not accurately reflect the instanced group's position during complex animations.PR created automatically by Jules for task 3380751165246601399 started by @jason420247
