OpenGL and EMBM question

[Matt Carlson]

I'm sorry if this isn't the place to post this but I couldn't find a more appropriate forum and the topic has at least been brought up here.

I am wanting to do some OpenGL development and would like to know if anyone knows of any documentation on the hooks for EMBM. I read here that someone has made a wrapper for QuakeII to use the bump mapping so I'm assuming is possible for me to do this.

EMBM is a function of D3D, not OGL.
You would need to re-write Matrox's ICD or TurboGL to add extensions for EMBM, and modify the game engine to support EMBM (good luck ).

As far as an OGL-D3D wrapper to be able to use EMBM in something like Q2...The only thing I am aware of is Egerter's work on some Q2 BSP files which he bumpmapped, but that was not playable in the game...he just used the .BSP map file, not the game engine itself.

If you look on www.egerter.com , in the "products" section, under "Power Render"/screenshots, you can see some pics of his bumpmapped BSP and other cool snapshots...
