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.
