I had a little trouble getting the Orange Book example to compile with vc8 / vs8 ( visual studio 8)

I got it working by doing the following:

* ..obviously adding include and lib paths...

Foxbat - keep an eye out for beta NVidia drivers that support advanced features before the release version.

Usually they will give you access to stuff you want a little earlier than waiting for...

Ah good to know - pity a 6800 at the moment would cost more than the rest of my PC combined :)

(and depreciate a lot faster too)

Does these mean the ATI cards can do early stencil rejection?

Interesting..... using the Nvidia FX Composer (DX HLSL tool) I looked at a Mandelbrot shader example there, and it had a "for" loop and it worked happily for me.

The number of "rolls" was...

I think it is. There was a mention of raytracing in the orange book and in the presentation of the Unreal 3 engine they speak of being able to do "ray tracing effects" on the GPU - don't know what...

Humus, your work is amazing. Don't let anyone flaming you (not here but elsewhere) put you off, keep up the good work.

BTW the dynamic branching doesn't seem to work with my NV5900 (forceware...

Thanks for the help.

Got a basic black Mandelbrot working. Now i have to look closer to tweak those pretty colours :)

Thanks, all the other OpenGL examples there look good too.

I suppose the lack of proper for loops means I can't get a Mandelbrot shader working on my 5900XT

does this mean it is just a matter of waiting for driver releases or upgrading hardware.

I'm talking about my 5900XT

I'm using ForceWare 62.11 and Shader Developer and the GSLDemo complain about not being able to use "for" loops. I also noticed this was an issue for current official ATI drivers.

Is there a...

do you need a driver for the AGP slot or an onboard vid card?

If it for a card - isn't the sis650 a TNT2 card? - and in that case you could just use the driver from www.nvidia.com

If your...

No, Cg will run on ATI just as esily.

My suggestion is buy the Orange Book - don't get Cg tutorial - it will assume too much.

The Orange book will take you from the ground up

I thought the orange book was indicating that the shader extensions are approved for inlcusion since 1.5?

Oh well live and learn

Thanks, I downloaded the leaked 62.11 nvidia drivers and it worked.

I just don't understand why my $300 video card can't run a standard like OpenGL 1.5 when I install an official driver that...

Ok this is really weird for me. I 've been programming OGL (fixed functionality) for years now but I've never really thought about drivers for OGL as such.

Now I'm trying to run the brick example...

If you just need ot to play OGL game sand stuff and you are using NVidia chips then just goto www.nvidia.com and hit "download drivers" and install the Nvidia drivers - that'll install OGL as well....

The difference is that Cg requires each vertex or fragment program in a serparate file and that file is processed by a serparate runtime compiler. Whereas in GL shading, you write your shader program...

The problem is that Bungie (makers of oni) used a fixed length string to hold all the GL extentions your card has. Of course this is fine until now when modern cards have heaps of extentions that...
