* 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. |
