Thanks ..I'll look into those classes immediately.

I know nodes own the geometry, but how can I differentiate between the types of geometry coming in? For instance, the sphere SOP has different primitive types (mesh, nurbs, bezier,polygon etc) so the representation in the SOP node , the geometry which is retrieved through gdp should have the geometric type info in it?? I guess I should look into the GEO and GU classes??

thanks

You want the objects in the scene to maintain their scale when the camera zooms in? Is that what you are trying to achieve?So objects wouldnt look bigger?Sorry just trying to understand what you are trying to say
