JPatch是一个spline的3D建模工具，支持OpenGL
JPatch is a spline based 3D modeling tool (a patch modeler). It can be used to create 3D models for POV-Ray or RenderMan® compatible renderers (e.g. Aqsis).
It is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License.
JPatch is work in progress. The current version (JPatch 0.4) supports modeling and some very basic animation features. There are develpment versions available (0.5.x) that support bones and a more sophisticated animator module, but this development branch has been discontinued.
The new development branch is no longer patch based, it’s now using Catmull- Clark subdivision surfaces. The new animator module will support many new features like a scene graph and inverse kinematics. A first version of this new code should be ready real soon now - but please keep in mind that I’m writing JPatch in my spare-time, so I can’t promise anything.
