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

NAME
genrbox - generate a RADIANCE description of a box SYNOPSIS
genrbox mat name xsiz ysiz zsiz [ -i ][ -r rad | -b bev ] DESCRIPTION
Genbox produces a RADIANCE scene description of a parallelepiped with one corner at the origin and the opposite corner at (xsiz, ysiz, zsiz). The sides of the box will be parallel to the three coordinate planes. The surfaces that make up the box will be modified by mat and their identifiers will begin with name. The -i option can be used to produce a box with inward directed surface normals. The -r option can be used to specify the radius for rounded edges. The -b option can be used to specify the indentation for beveled edges. EXAMPLE
To produce a rectangular box made of wood with beveled edges: genrbox wood box1 5 8 3 -b .5 > box1 AUTHOR
Greg Ward BUGS
Because spheres and cylinders are used to construct boxes with rounded edges, a transparent box of this type appears quite messy. SEE ALSO
