Axolotl provides a set of volumetric modeling components for Rhino Grasshopper. They come as GH user objects and most of them are Python scripts. The range of possible applications is very broad, it allows to explore an unlimited geometric freedom. It is thought and used as a teaching resource. It’s main focus is therefore on openness and readability rather than performance.

Keywords: signed distance fields (SDF), voxel space, function representation (FRep), constructive solid geometry (CSG), implicit surface
