5 * Radiance animation control program
6 *
7 * The main difference between this program and ranimove is that
8 * we have many optimizations here for camera motion in static
9 * environments, calling rpict and pinterp on multiple processors,
10 * where ranimove puts its emphasis on object motion, and does
11 * not use any external programs for image generation.
12 *
13 * See the ranimate(1) man page for further details.
