Conversation
Replaced individual mesh rendering with InstancedMesh in QuantumScene.tsx
to significantly reduce draw calls and improve performance.
- Implemented THREE.InstancedMesh in MicrotubuleTorus
- Added useFrame logic with THREE.Object3D for efficient matrix updates
- Set frustumCulled={false} for stable rendering
- Added key={count} for dynamic instance count handling

💡 What: Replaced the individual
<mesh>component-per-cube implementation with a single<instancedMesh>in theMicrotubuleToruscomponent.🎯 Why: The previous implementation rendered each of the 1080 cubes (360 + 720) as a separate mesh, leading to excessive draw calls that severely impact GPU performance. Using
InstancedMeshallows Three.js to render all identical geometries in a single call.📊 Measured Improvement: Theoretical reduction in structure-related draw calls from 1080 to 2. Total scene draw calls reduced from approximately 1082 to 4 (including lighting), representing a >99% improvement in rendering efficiency for the microtubule structures.
