Demo is available on the web site. Quirky, but advanced modeling. Animation controls are a bit lacking. Rendering quality is wonderful. Needs a lot of machine to run very smoothly if you get the newest version.
Interface is really hard to figure out.
Powerful and fast, but strangely implemented polygon modeling. Rendering is basic. Hardware requirements are very reasonable. Demo available on the site. Extremely malleable modeling, but no automated creation or deformation tools.
