Remove backface culling
Utilize instancing
Texture Optimization
Compress textures
Use power-of-two sizes
Generate mipmaps
Minimize bind calls
Shader Optimization
Simplify complex expressions
Use precision qualifiers
Minimize branching
Optimize math operations
Optimized Shader Example
precision mediump float;
uniform vec2 u_mouse;
uniform float u_time;
varying vec2 vUv;
void main() {
// Optimized fragment shader
vec2 uv = vUv;
uv += sin(u_time * 0.5) * 0.05;
float d = length(uv) * 2.0;
// Simple efficient coloring
vec3 color = vec3(
sin(d) * 0.5 + 0.5,
cos(d) * 0.5 + 0.5,
sin(u_time) * 0.5 + 0.5
);
gl_FragColor = vec4(color, 1.0);
}
Performance Optimization
Memory Management
- • Use typed arrays instead of arrays
- • Avoid memory fragmentation
- • Use object pooling for frequent allocations
- • Implement resource recycling
GPU Utilization
- • Maximize parallel processing
- • Balance workload between CPU/GPU
- • Use GPU memory efficiently
- • Minimize GPU idle time
Performance Monitoring
Use browser developer tools to monitor:
- • WebGL rendering performance
- • JavaScript CPU usage
- • Memory allocation patterns
- • GPU frame rendering times
- • Network resource loading
