Cut and paste the following in a shell window:

cat <<EOF >fragmentProgram.cg

void main(

out float4 color : COLOR,

in float2 tc0 : TEXCOORD0,

uniform samplerRECT tex0 : TEXUNIT0,

uniform float4 gamma : C0

)

{

float4 t0 = texRECT(tex0, tc0);

color = pow(t0, gamma);

}

EOF

/usr/bin/cgc -profile arbfp1 fragmentProgram.cg

This will produce an ARB fragment program that you can

feed directly to glProgramStringARB

To everyone and anyone on the list,

I'm a newbie to OpenGl and want to learn how to
program.

I downloaded the Cg toolkit for Mac from NVidia's Web
site. I also have the book "The Cg Tutorial" by
Fernando and Kilgard published by NVidia.

I may seem completely ignorant, but I can't figure out
how to use the toolkit. NVidia's Web site tells which
folder from the download contains the compiler, but
there's only a UNIX window in that folder.

I would guess that I can use the toolkit in XCode but
I don't know how to set it up. Perhaps I need to learn
a little more about C or C++.

Is there anyone that can help? Any ideas would be
greatly appreciated.

Thanks for your help.

Peter
