/*
 * sample.c - Simple file to make a scene with a few objects
 *
 * Author:  Alexander Enzmann
 *
 * Modified: 1 September 1993
 *           Eric Haines
 *           changed file name, made sure values were passed as doubles
 *           (the HPUX compiler sees "..., 5, ..." as an integer and merrily
 *           passes the integer representation down to the subroutine which
 *           wants a double).
 *
 * size_factor is ignored.
 *
 * size_factor # spheres   # squares
 *      x          xx           x
