Overview
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.
Examples
