Polygon Generation Routines
ISOSURF, data, valu, vert, poly
Standard Library procedure that computes, and optionally displays, an isosurface of the specified 3D data.
POLY_SPHERE, radius, px, py, vertex_list, polygon_list
Generates the vertex list and polygon list that represent a sphere.
POLY_SURF, surf_dat, vertex_list, polygon_list, pg_num
Generates a 3D vertex list and a polygon list, given a 2D array containing Z values.
SHADE_VOLUME, volume, value, vertex, poly
Given a 3D volume and a contour value, produces a list of vertices and polygons describing the contour surface (also known as an iso-surface).
