creating geometry together with swarms

drawing 2D shapes with basic swarm/boid brush behaviour

This simple swarm logic driven drawing tool uses the p5.js canvas and the warm boid movement to draw pseudo 3D shapes with plain ellipses. The variation of individual boid mouse follow behaviour and velocity smoothing is used in this case to invoke shape like drawing.

With Hunyuan3D 2.1 we have an pretty capable Open Source Model to generate geometries from plain flat 2 graphics. In ComfyUI we can use this model even with a pretty low VRAM requirement of 8-12GB. The model works best, when the drawings have distinct visible and plausibe shapes.
