Real 3D, one of the first solid modelers featuring constructive geometry, boolean operations and smooth surfaces, also debuted on the #Amiga.
Real 3D was very advanced for its time, but also harder to learn. I never went beyond modeling simple shapes with it, but I had an older friend who was using Real 3D for architecture.
Lots of great 3D modelers and ray tracers originated on #AmigaOS:
