software model

The "software model" is a C++ representation of the OpenGL pipeline of the hardware. The purpose of the model is to describe the inner workings of the rendering engine, but it's also designed to run as part of a program that simulates the hardware. Think of the model as a very detailed spec that also simulates what it describes. The model source code is licensed as Free Software under the GNU General Public License (GPL) and it has been agreed that the model serves as documentation upon which a chip design can be based.

The model is also maintained in a Subversion repository at
https://svn.suug.ch/repos/opengraphics/main/trunk/model

To checkout a copy of the model, first install subversion, then run

There is a new model at https://svn.suug.ch/repos/opengraphics/main/trunk/new_model rewritten for clean-room purpose(as mentioned in OGPN8: June 3rd 2006). However, we are in the process of testing it and integrating it with the OpengraphicsSimulator. Feel free to check out the new model and help in this process.
