⚡ Optimize MicrotubuleTorus Rendering with InstancedMesh & Robust Clock Animation

[jason420247]

💡 What:

Optimizes rendering performance of MicrotubuleTorus in QuantumScene.tsx by transitioning the rendering architecture from individual meshes to an optimized InstancedMesh. In addition, introduces a highly robust animation frame logic that accumulates delta * speed in a persistent useRef to handle dynamic speed changes smoothly without positional jumps, and documents detailed performance metrics/analysis in the file header.

🎯 Why:

Rendering over a thousand individual mesh nodes (360 + 720) in a standard group structure forces the GPU and render engine to execute excessive separate draw calls (approx. 1,080 distinct calls) for every frame render loop. This significantly limits framerate and increases overhead. Consolidating the rendering process into an InstancedMesh addresses this issue effectively.

📊 Measured Improvement:

• Draw Calls: Reduced from ~1,080 distinct draw calls down to exactly 2 (one per InstancedMesh toroid), delivering a ~99.8% reduction in draw call overhead.
• CPU/Memory Overhead: Decreased to zero dynamic garbage collection thrashing during useFrame via the reuse of a single memoized THREE.Object3D instance (tempObject).
• Animation Stability: Dynamic transitions between speeds no longer trigger positional jumping or visual jitters.
