Jason LaDere has started a Blender to Java port as a personal learning project. So far, he claims that basic functionality is already working (unconfirmed, as it doesn't run on OSX yet). I must say that I have serious doubts about the usefulness of a Java version of Blender (maintaining it would be a hell of a job), BUT I do think it's a tribute to the spirit of Open Source. What's your opinion?
I have started a Java port of the Blender 3D software. Currently it is capable of loading/saving files, manipulating UI, rendering, and editing meshes. I am curious to see how much interest there is in this project, so please check it out.
So far this a proof of concept work to see how many people might be interested in this project. The Blender Java version available through webstart and depicted in most of the screenshots is based on Blender 2.48a code. I also have another version based on the current 2.5 code which can be seen in the last screenshot. The 2.5 version is not as far along yet. Blender Java uses JOGL for 3D rendering.
