The University of Pennsylvania's GRASP lab is looking for a CAD/rendering
package to be used to display and manipulate images of superquadrics for
computer vision research. While we are most interested in publicly
available packages, we would like to obtain more information or reviews
of any systems capable of performing the functions listed below.
Any advice or suggestions are greatly appreciated.
Required:
. Sun SparcStation compatibility and X11 support.
. C callable.
. User defined primitives which allow the rendering of superquadric
surfaces while maintaining a compact representation of superquadric
objects. Also desire ability to render functions and splines.
(Does there exist a package with sufficiently complex primitives to
prevent us from having to continually generate our own wireframes?)
. 3d rendering using perspective projection and ability for real-time
on-screen viewing.
. Ability to manipulate multiple objects.
. At least basic binary operations on objects.
Desired:
. Capability for bit map display.
. Constant shading.
