Hello Joakim,
It works fine now with little amendment mentioned in bold text
Are they conceptually ok - the 2 lines in bold text?
******************************
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());
****************************
I replaced them with the following one
***********************
ref_ptr<Group> root = new Group();
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> capsuleVertexShader = new Shader(Shader::VERTEX);
capsuleVertexShader->loadShaderSourceFromFile("shaderSRC/gooch.vert");
ref_ptr<Shader> capsuleFragmentShader = new Shader(Shader::FRAGMENT);
capsuleFragmentShader->loadShaderSourceFromFile("shaderSRC/gooch.frag");
*
capsuleProgramObject->addShader(capsuleVertexShader.get());
capsuleProgramObject->addShader(capsuleFragmentShader.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());
