Learn how to create repeating geometric patterns in GLSL shaders.
- Understand how to use modulo operations for pattern repetition
- Learn coordinate transformation and scaling techniques
- Master creating tiled effects
Use the mod()
function to create repetition:
`
glsl
vec2 repeatedUV = mod(uv * scale, 1.0);
`
Control repetition count by scaling UV coordinates:
- Larger scale values = more repetitions
- Smaller scale values = fewer repetitions
Steps to create tiled effects:
1. Scale UV coordinates
2. Apply modulo operation
3. Draw pattern within each tile
Create a repeating circular pattern arranged in a grid across the screen.
1. Use mod(uv * 4.0, 1.0)
to create a 4x4 repetition grid
2. Draw circles centered in each tile
3. Use distance()
function to calculate distance to tile center
4. Use smoothstep()
to create smooth circular edges
You should see a neat grid of circular patterns, with each circle centered within its tile.
