I have successfully used the program Quat to create 3D fractal objects. I have also changed the parameter for the 4th dimension using a batch program and created good movies of morphing 3D projections of 4D objects. Dirk Meyer's Quat web pages: http://www.physcip.uni-stuttgart.de/phy11733/index_e.html There's a Quat mailing list and a Quat Artists Forum as well as fractal galleries. You can make left/right eye view stereoscopic 3D objects. There are a Windows installer and uninstaller. Quat is GNU public license. - Hal Lane ######################### # hallane@earthlink.net # ######################### -- No virus found in this outgoing message. Checked by AVG Free Edition.
