Ripple Shader in Godot

I wanted to play with glsl and godot, so I experimented with making a ripple effect inspired by the macOS Drift screensaver.

Each line is drawn with a shader

Roughly, the high level steps were:

• Spawn a grid of mesh instances using MeshInstance2D
• Space them out organically in a circle using blue noise
• Render each mesh’s texture with a shader
• Draw a segment using Inigo Quilez’s 2D distance functions
• Pass in noise and sample based on time to get scrolling effect
• Pass in position of each mesh to know where to sample the noise
• Offset segment angles, thickness and color based on noise value
