NAME
       genprism - generate a RADIANCE description of a prism

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

DESCRIPTION
       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  ver-
       tices,  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.

EXAMPLE
       To produce a equilateral triangular prism:

	 genprism clear_plastic prism 3 0 0 .5 .866 1 0

BUGS
       The rounding option only works for opaque prisms with outward facing normals.  If the normals face inward, the appearance will be bizarre.
