What’s more pathetic is this guy’s unoriginal SoC application is accepted. As a mentor , I saw rejected proposals that are better than this. There’s even 1 person that submitted 6 long proposals that I believe should be accepted, how unfortunate that I was not a mentor of that organization.

The light tunnel effect could be easily rewritten using the built-in GLSL step function avoiding the if statement.

The conditionals used in those snippets of example code could probably be managed without falling back to an entirely software path, but performance would be pretty bad as you end up executing every code path, per pixel.

I just wrote a library to play with shaders, you can find a blogpost about it here : http://asabil.wordpress.com/2007/04/16/bling-a-small-shader-library/ Actually, you shaders are supported by your driver, except that GLSL is not, basically you can try to grab the latest Mesa, and in its source tree, you will find an offline glsl compiler that will produce ARB_fragment_program code, that can be used.

I cant even count how many concepts are just straight ripped off Mac OS X.

Anyhow, its just sad.. all the copying that is being done.

That is why I was a former OSS developer and switched.

I have the same card, and I was always under the impression that Intel cards had very good support in Linux (drivers being open source and all), but this is sadly not the case. I'll be getting an NVidia card soon. I feel your pain.
