Blender made it to #5 is this years's retrospective by CGSociety!
Blender 3D has been with us a few years and its great to see the popularity of this open source, free 3D software isn't waning. In fact, the features continue to pile up, with a new UI, full polygon modeling, B-Spline curves, a full character rigging deck and its own animation tools. The latest features include some pretty quality rendering systems, a built-in ray tracer, UV unwrapping ability, a cool physics engine and a real-time game engine installed.
