Hi Amal, You might be able to do everything you want just with a standard osg::Geometry and do all the parametric work in shaders. See the osgparametric example (its very simply shader but might give you a bit of inspiration.)

Basically Iam deriving a class called osgCubic from osgDrawable . This class will use shaders to render a cubic equation (any genera cubic equation) . So can I know what all functions should I be implementing in the class. Actually Iam trying to implement only the drawImplementation function in which Iam trying to use the osgShader. Is it a right method to go about doing it ?

To: osg users <osg-users@openscenegraph.net> If i derive a class from osg:drawable ( say like osg::Text ) what are the functions that I should surely overload ?. One is DrawImplementation function. Are ther any other Functions that i should surely overload . You only need override pure virtual methods, and drawImplementation() is the only pure virtual method in the Drawable class. Depending on what you're doing, you might also want to override the destructor, or computeBound(), but this isn't strictly required and, as I said, depends on what you're doing.
