Terrain Test

While working on some rocks for MediaLab, I decided to do some research into how other people have created rocky environments that are both quick to make and to render - I found one method that uses an asteroid generator script at http://vray.info/tutorials/vrayrocks/default.asp and did a quick test. 

To make the scene only took about 10 minutes, and render time was just under an hour.  There's still some geo tearing from the displacement but the method centers around using a combination of bump and displacement maps to generate the rocky surface.  It's a technique I applied to the rocks I was working on, and even on a smaller scale like lawn decorations it produces a good, convincing result.
