⚡ Optimize MicrotubuleTorus with InstancedMesh#72
Conversation
Replaced individual mesh rendering with InstancedMesh to reduce draw calls from ~1082 to ~4. Implemented matrix reuse and proper instance count handling. Co-authored-by: jason420247 <44763042+jason420247@users.noreply.github.com>

💡 What: Replaced individual mesh rendering with
InstancedMeshin theMicrotubuleToruscomponent withinQuantumScene.tsx.🎯 Why: The original implementation rendered 1080 individual meshes (360 + 720), resulting in excessive draw calls. Using
InstancedMeshallows these to be rendered in just 2 draw calls (one per component instance).📊 Measured Improvement: Theoretical reduction from approximately 1082 draw calls (1080 meshes + 2 lights) to approximately 4 draw calls (2 instanced meshes + 2 lights). This represents a >99% reduction in draw call overhead for the scene, significantly improving frame times and efficiency.
Key Implementation Details:
THREE.InstancedMeshfor efficient batch rendering.THREE.Object3Dfor matrix transformations within theuseFrameloop to minimize garbage collection overhead.key={count}to ensure theInstancedMeshremounts and reallocates its internal buffers if the instance count changes.frustumCulled={false}to ensure instances remain visible during animations without the need for manual bounding box updates.MicrotubuleTorusfor improved modularity and testability.PR created automatically by Jules for task 2277897810227859063 started by @jason420247
