Makepad Shader Demo

A GPU shader demo built with Makepad, featuring raymarched 3D graphics.

Shaders

Gyroid Shader

Raymarched gyroid mathematical surface with:

• Two interlocking gyroid structures (blue/orange)
• Diffuse, specular lighting
• Ambient occlusion
• Fog and vignette effects
• Animated camera

Volumetric Orbs (commented out)

3 colored orbiting lights with volumetric glow effect.

Run

cargo run --release

Makepad Shader Learnings

Key constraints discovered during development:

1. No variable reassignment - Use unique names for each computation step
2. Avoid time as instance name - Conflicts with built-ins
3. Inline complex logic - Helper functions can cause silent failures
4. Manual loop unrolling - For raymarching reliability
