I stumbled across Cheetah 3D for the Mac OSX on the App Store several weeks ago and wanted to try it out. To my surprise it is a very intuitive 3D application. I’m fairly proficient with basic modeling techniques in Maya, and I have to say, Cheetah 3D is a much easier tool to produce decent and quick results. Check out the video of a cartoonish style women’s head. I modeled this with polygons and subdivision and textured this within several hours without any prior training or use of Cheetah 3D. I’d highly recommend this App. I am considering writing an iBook with some general tutorials for modeling basic human heads as seen here.
