According to everything I have read, They still don't make meodels "compatable " with other modelers, they are program libraries to animate and render on the fly for real time animation. But if you wish to read more about some of the programs send e-mail to: Criterion (Render Ware) rw-support@criterion.canon.co.uk RenderMorphics (Reality Lab) info@render.com SGI and MS for OpenGL and Appel QuickDRAW Gx be easily found in their respective forums here on CIS.

To put it another way, each of those four APIs has their own file format: QuickDraw 3D metafile, OpenGL has "GLS" (a stream representing the drawing commands) and arguably Open Inventor format, Reality Lab RenderMorphics has XOF files, and Keystone will certainly use Open Inventor.
