I’ve actually got a crazy idea for doing procedural trees using distance fields from curves. During my day job i’m often doing crazy volume compositing using distance fields and noise. Mostly for clouds but it would be fun to have a curve that generated a distance field that could then have a raytraced surface shader. I’ve got a procedural geometry that generates slices from back to front order so that translucent compositing works from any angle. It’s faster slightly faster than raytracing. It was made to render volumes but I could use it to render isosurfaces as well i think.
Probably wont work but weve got to at least come up with some crazy ideas.
