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).
