Thanks Joakim,
I believe that sharing the stateset will be required here
I am trying to attach a simple shader but sharing the stateset is not giving
me the result
that i am supposed to have....
******************************
ref_ptr<Geode> capsuleGeode = new Geode;
ref_ptr<Capsule> capsuleShape = new Capsule(Vec3f(3,0,0),1,2);
ref_ptr<ShapeDrawable> capsuleDrawable = new
ShapeDrawable(capsuleShape.get());
capsuleGeode->addDrawable(capsuleDrawable.get());
ref_ptr<StateSet> capsuleState = capsuleGeode->getOrCreateStateSet();
//create the shader parameters
ref_ptr<Program> capsuleProgramObject = new Program;
ref_ptr<Shader> capsuleVertexObject = new
Shader(*(Shader::readShaderFile(Shader::VERTEX,"shaderSRC/gooch.vert")));
ref_ptr<Shader> capsuleFragmentObject = new
Shader(*(Shader::readShaderFile(Shader::FRAGMENT,"shaderSRC/gooch.vert")));
capsuleProgramObject->addShader(capsuleVertexObject.get());
capsuleProgramObject->addShader(capsuleFragmentObject.get());
//create a new stateset
//with the default setting
capsuleState->setAttribute(capsuleProgramObject.get());
//Passing the uniform variable representing the texture to the shader
capsuleState->addUniform(new
osg::Uniform("LightPosition",osg::Vec3(0,0,10)));
capsuleState->addUniform(new
osg::Uniform("SurfaceColor",osg::Vec3(0.75,0.75,0.75)));
capsuleState->addUniform(new osg::Uniform("WarmColor",osg::Vec3(1,0,0)));
capsuleState->addUniform(new
osg::Uniform("CoolColor",osg::Vec3(0,0,0.6)));
capsuleState->addUniform(new osg::Uniform("DiffuseWarm",0.45f));
capsuleState->addUniform(new osg::Uniform("DiffuseCool", 0.45f));
root->addChild(capsuleGeode.get());

Any hint?
