OGLE

Eyebeam R&D have just announced the release of OGLE, a graphics extractor that intercepts OpenGL messages, and allows users to capture and save 3D data dumps that can be repurposed in a variety of ways.

This tool can be used to extract scene geometry or characters from applications running on Windows, and import this 3D data into other applications, where it can be edited, rendered, printed, mashed, or simply admired. Check out the examples to get a better idea of it's capabilites. All the code is GPLd, which indicates that this is really just the beginning...
