How would you optimize a Babylon.js scene to reduce draw calls and improve performance?
To optimize a Babylon.js scene, follow these steps :
1. Merge meshes : Combine static meshes sharing the same material to reduce draw calls.
2. Use instances : Create multiple instances of a mesh if they share geometry and materials.
3. LOD (Level of Detail) : Implement different levels of detail for objects based on camera distance.
4. Occlusion culling : Hide objects not visible to the camera to avoid unnecessary rendering.
5. Frustum culling : Exclude objects outside the camera’s view frustum from rendering.
6. Optimize shaders : Minimize shader complexity and use simpler materials when possible.
7. Texture atlas : Combine textures into a single image to reduce texture switching.
