Draw Call Batching
Draw calls are expensive GPU operations:
- Static batching: Pre-combined meshes
- Dynamic batching: Runtime mesh combining
- GPU instancing: Multiple identical objects
- Material batching: Shared materials
Texture Atlasing
Combine multiple textures into atlases:
- Reduces texture switches
- Sprite sheets for 2D games
- Texture arrays for variations
- Mipmap optimization
Mesh Optimization
- LOD (Level of Detail) systems
- Polygon reduction for distant objects
- Occlusion culling
- Frustum culling
- Mesh combining tools
Shader Optimization
- Minimize shader variants
- Share shader programs
- Reduce texture samples
- Optimize vertex calculations
Memory Management
- Texture compression
- Vertex buffer pooling
- Resource streaming
- Garbage collection minimization
Conclusion
Batching techniques dramatically reduce draw calls and improve frame rates by combining geometry, optimizing materials, and managing GPU resources efficiently for smooth gameplay performance.
