3 * ranimove.h
4 *
5 * Radiance object animation program
6 *
7 * The main difference between this program and ranimate is that
8 * ranimove is optimized for object motion, and includes a complete
9 * blur simulation. We also have a number of clever schemes
10 * for optimizing the computation, allowing rendering time
11 * per frame and noticeable difference threshold to be specified.
12 * Parallel rendering uses multiple processors on the local host,
13 * and network rendering is not directly supported. (However, no
14 * one says you can't run ranimove on other machines at the
15 * same time; just be careful not to overlap frames.)
16 *
17 * See the ranimove(1) man page for further details.
