I have to start my review by saying that I'm not the biggest fan of Kai Krause programs. The non-standard interface and the "just explore" atitude of Metacreations irritates me so I have a bias. I was disappointed with this book because it provides no great insight beyond the so-so manual Metacreations includes with Bryce 3d. Examples in this books don't provide little insight into "natural" effects(or even stuff from Planetary Traveller) but instead spend a lot of time making levitating silver balls reflecting the environment. Cool effects in '85 on an Amiga 1000 but not now. I don't think it is worth the money.
