⚡ [optimize microtubule torus with instanced mesh]#74
Hidden character warning
Conversation
- Replaced individual mesh instances with InstancedMesh in MicrotubuleTorus.
- Used useMemo for Object3D matrix helper to avoid per-frame allocations.
- Optimized useFrame loop for matrix updates.
- Added key={count} and frustumCulled={false} for robustness.
- Reduced draw calls from ~1082 to ~4.

💡 What:
The
MicrotubuleToruscomponent was refactored to useTHREE.InstancedMeshinstead of rendering individual<mesh>components for each cube.🎯 Why:
Rendering 1080 individual meshes (360 + 720) was extremely expensive, resulting in over 1000 draw calls per frame. This caused significant CPU overhead and GPU bottlenecking. By using
InstancedMesh, all instances of the same geometry and material are sent to the GPU in a single draw call.📊 Measured Improvement:
