摘要：

The author considers the problem, in making space movies, of figuring out where to place the camera and in what direction to point it to get an interesting picture. He develops an approach whereby the program is told what is to appear on the screen and determines where to place and point the camera. He bases the approach on the standard 'look at' transformation.
