Rotate on axis detailed 3d animation - what program to use?

I want to rotate a 3d image on a vertical axis with momentum in a swf file. (similar to this http://ringoblog.com/wp-content/uploads/2008/05/to22.jpg ) I dont know of any way to make detailed shading/lighting/reflections "photo-realistic" in Flash however. I can always import the image to Flash and create artificial momentum, so that is not a problem - all I need is a method of creating a realistic rotating image to import either entirely or frame by frame. The only way I know of doing this is drawing each frame individually in Photoshop - which would take forever. I know CAD programs can do something similar to creating an entire rotatable 3d object relatively easily, although the last one I worked with did not enable skinning (not that I knew how to). Anyone know of any easy-to-learn programs I can do this with? (preferably free, or with an unbranded, unrestricted trial)
