Canvas & WebGL Performance Protocol

High-framerate 2D and 3D graphics rendering in browser environments.

---

1. Render Loop & Animation Frames

1. Always drive animations via requestAnimationFrame(), never setInterval().
2. Calculate delta time (deltaTime = now - lastTime) to decouple animation speed from screen refresh rates.

2. Memory & Buffer Disposal

• Explicitly dispose of textures, vertex buffers, and shaders when destroying canvas scenes to prevent GPU memory leaks.
