OpenGL Emulating missing OpenGL extensions?!

I am currently doing quite a lot of development work on my Asus S5200 laptop, which is a great computer that has everything I need, yet weights close to nothing and has great battery life (if you are looking for a super laptop, check it out!). I can program wherever I go. On the bus, in a restaurant, sitting in a tree, or while bungie jumping. However, it has one big problem, which is it has a graphics card (Intel Extreme Graphics 2 for Mobile) with little or no native support for any useful OpenGL extensions. I am currently working on an OpenGL based game using shadow maps, which requires support for the GL_ARB_depth_texture extension. Unfortunately my graphics card simply just does not support this extension, so how can I test if my code is working properly? So, I thought, maybe there are some OpenGL extension emulators out there, or some pure software only drivers for the newest OpenGL verions with all bells and whistles included? I do not mind if it is slow, in fact "slow" is almost a nice feature as I forces me to optimize, but it is important I can test new 3D techniques on my non-game-optimized 3D card. Not only through the above mentioned extension, but also other new features like shaders etc. Buying a bulky and heavy monster PC with the latest graphics card is just not very tempting, and I rarely work on a desktop these days... Any solutions to this one? Thanks in advance! :)

Look at mesa3d.org. It's a software OpenGL implementation. Performance will suck, but that's OK if all you're doing is prototyping, and testing correctness.

If you have an NVidia card, you might want to try NVemulate


Yeah, I found this one, but as mentioned it is an Intel based card... :(

Uhm, no, I really mean I have an Intel based card, so I cannot use an nvidia emulator. Sorry if I was not clear... :)
