genprism - generate a RADIANCE description of a prism


genprism mat name { - | vfile | N v1 v2 .. vN } [ -l lvect ][ -r radius ][ -c ][ -e ]


Genprism produces a RADIANCE scene description of a prism, or extruded polygon. The
polygon to extrude lies in the z==0 plane, and is given as a list of (x,y) pairs on the
standard input (-), or from the file vfile, or on the command line preceded by the number
of vertices, N. The order of the vertices and the extrusion vector lvect (default
(0,0,1)) determine the surface orientations. The surfaces that make up the prism will be
modified by mat and their identifiers will begin with name. The -r option may be used to
round the corners of the object using spheres and cylinders. The -c option inhibits
generation of a face connecting the last vertex to the first. The -e option inhibits
generation of the end polygons.


To produce a equilateral triangular prism:
