i'm also quite new to the GLSL part in OpenSG, but it worked almost at once...
1) create an shl chunk
SHLChunkPtr shl = SHLChunk::create();
beginEditCP(shl);
shl->readVertexProgram(...);
shl->readFragmentProgram(...);
// if necessary, pass some params to the shader program
shl->setUniformParameter(...);
endEditCP(shl);
2) add it to your material
SimpleMaterialPtr mat = SimpleMaterial::create();
beginEditCP(mat);
// set other params ...
mat->setAmbient (Color3f(0.0,0.0,0.0));
mat->setDiffuse (Color3f(...));
mat->setEmission (Color3f(0.0,0.0,0.0));
mat->setSpecular (Color3f(0.3,0.3,0.3));
mat->setShininess (5.0f);
mat->setTransparency (0.0f);
mat->setColorMaterial(GL_AMBIENT_AND_DIFFUSE);
// add the GLSL part
mat->addChunk(shl);
// add texture chunks
mat->addChunk(texChunk);
endEditCP(mat);
cheers,
simon
