Thank you, Dr. Geep for extending class a bit longer (I got here late, have a cold, you can ask my mom, honest!) It seems to me that your point "Is this polygon in violation of copyright laws?" might also apply to the Poser primitives, no? CL cannot copyright the forms 'Square, Box, Ball, Cone, Cylinder', certainly, but what about their particular Box, Ball, etc. the meshes of which actually are different from the Cube, Sphere, etc. primitives in say Carrara? Someone said that the piece of mesh had to be "recognizable", but the Poser sphere is more recognizable than your example polygon, and so more 'copyrightable', yes? kawecki, your point is mine also: Who can assure me that CL couldn't conceivably tell me someday that my mesh using their primitive is a copyright violation even if their EULA says otherwise?
