@sjb3d yes, I managed to find a way to cull the trees (currently two-level). it’s still very limited though. Compound sdfs definitely have artifacts (especially the interior region). but users may still prefer at least having some ways to localize the boolean operations.
@ephtracy nice, even two-level sounds super useful. I had a vague plan in Dreams to support compound shapes made from only two built-in shapes, so at least users could make some custom shapes to sculpt/paint with, but this was probably too limited/hacky and still had massive workflow and UI impact!
SDF is referred to as the "Signed Distance Field". the work is mainly based on the prior R&D work from @iquilezles, @mmalex, @sjb3d and @lritter, and I'm glad that I also developed some of my own techniques in this program. #magicaCSG
