Learn how to create anti-aliased, smooth edges in your shader graphics.
- Understand the importance of anti-aliasing in shaders
- Learn to use smoothstep() function effectively
- Practice creating smooth transitions between colors
Smooth edges prevent jagged, pixelated appearance:
- Sharp transitions create aliasing artifacts
- Smooth transitions look more professional
- Essential for high-quality graphics
The smoothstep(edge0, edge1, x) function:
- Returns 0.0 when x <= edge0
- Returns 1.0 when x >= edge1
- Smooth interpolation between edge0 and edge1
- Creates natural-looking transitions
Control smoothness by adjusting edge parameters:
- Smaller difference = sharper edge
- Larger difference = softer edge
Create a circle with perfectly smooth, anti-aliased edges.
1. Calculate distance from center: distance(uv, center)
2. Use smoothstep() instead of step() for the edge
3. Try: smoothstep(radius + 0.01, radius - 0.01, dist)
4. Experiment with different edge widths
5. Compare with sharp edges to see the difference
You should see a circle with perfectly smooth edges, free from pixelation or jagged artifacts.
