What is the Glide current version?
The current version of Linux Glide is 2.4. The next version will probably be identical to the current version for DOS/Windows, which is 2.4.3, which comes in two distributions. Right now, various parts of Glide are different for Voodoo Rush ™ (VR) and Voodoo Graphics ™ (VG) boards. Thus you have to pick up separate distributions (under Windows) for VR and VG. The same will be true for Linux. There will possibly be another chunk of code and another distribution for Voodoo 2 ™ (V2) boards. There is also a Glide 3.0 in preparation that will extend the API for use of triangle fans and triangle strips, and provide better state change optimization. Support for fans and strips will in some situations significantly reduce the amount of data sent ber triangle, and the Mesa driver will benefit from this, as the OpenGL API has separate modes for this. For a detailed explanation on this see e.g. the OpenGL documentation.
