Antiprism makes polyhedron models to view and analyze. Exports to VRML, POV-Ray and LiveGraphics3D. Includes standard polyhedra and transformations to construct new ones. Antiprism is a set of programs for generating, manipulating, transforming and visualising polyhedra.

Antiprism Features:
Display
* antiview - interactive OFF file viewer

Conversion
* off2pov - converts OFF files to POV format
* off2vrml - converts OFF files to VRML format
* off2m - converts an OFF file to LiveGraphics3D 'm' format
* off2crds - converts an OFF file to a coordinate file
* crds2off - converts a coordinate file to OFF format
* m2off - converts a LiveGraphics3D 'm' file to OFF format

Manipulation
* off_color - adds colours to an OFF file
* off_trans - transformations (rotations, translations, etc) of OFF files
* off_align - alignment of OFF files
* off_util - utilities for OFF files (orientation, merging, etc)

Reporting
* off_report - report of global measures (e.g. area, volume, centroid), maxima, and counts
* off_query - list element data

Generation
* conv_hull - convex hulls (using Qhull)
* pol_recip - polar reciprocals (duals)
* geodesic - geodesic spheres
* unipoly - uniform polyhedra (using Kaleido)
* johnson - Johnson polyhedra
* polygon - polygon based polyhedra (prisms, pyramids, etc)
* iso_delta - isohedral deltahedra
* conway - Conway Notation transformations
* poly_kscope - polyhedral kaleidoscope
* unitile2d - makes uniform tilings on a surface
* string_art - string figures
