48. Antimony
With his hands in hardware, firmware, software, and design, Matt Keeter has a special interest in making interactive things and rapid prototyping and fabrication. That’s why he built Antimony as a 3D CAD modeling tool that “evolved from Lisp machines rather than drafting tables.”
Key Features:

  • Built on three axes: a framework for tracking information flow through directed acyclic graphs, a geometry engine for doing CSG, and a standard library of shapes and transforms
  • Solid modeling is done by connecting nodes in a graph
  • Graph engine scales up to complex multi-part assemblies
  • Geometry engine uses functional representations for solid modeling, which is ideal for modeling with boolean operations
  • Geometry engine renders shapes as shaded bitmaps and then bits them to a 3D viewpoint
  • Define custom shapes
