Codex Perductum

Terragen is a wacked out image generation program. It renders photo-realistic landscapes based on fractals and [I assume] ray tracing. Snow, desert, vegetation, water, sky all look very real. The last time I looked at this stuff was 10 years ago and it sure has come a long way. Click on the image at the left and check out some of the galleries to see examples of what the users can do with it.
