Rendering is pretty good. Runs on Powermacs only. Big file to download. Vision 3d I couldn't find an url for it, but I'm pretty sure it's on the net somewhere. This programs is basically one step below a pretty good commercial program.
Interface is more or less standard.
Modeling is good but not flexible. Animation is basic. Rendering is okay. The first program I found that output to 3DMF files. 2D image software is usually a bit more intuitive, and usually less expensive.
