[osg-users] Modern GLSL and OSG

[Garth D]

Hi all,

I was wondering if anyone can make some suggestions as to resources that 
are useful for learning GLSL in modern OpenGL (say, 3.0+) with a 
specific focus on use with OSG.

My existing GLSL knowledge is weak compared to my general 3D knowledge, 
and mostly dates back to the early days of shaders. A lot of what I have 
personally done with OpenGL and OSG has involved the fixed-function 
pipeline, or things that map to it fairly closely.

Thus far I've been digging around online for GLSL resources, but tend to 
frequently find myself doing it the wrong way as I'm using features that 
have since become deprecated. On the OSG side I tend to dig around in 
the OSG examples and search the source to try to find the OSG 
equivalents to OpenGL calls I see mentioned in the GLSL resources. I 
then put these together and if I'm lucky something useful comes out. :)

I think I'll figure things out eventually if I continue to crash around 
blindly as I have been, but if anyone can suggest some better starting 
points for GLSL use in OSG specifically, it would be much appreciated. :)

Cheers,
Garth
