Hi all, I am developing an app where i need to have SphereSegment-like geometry changing dynamically, so i just wanted to know the advantages that osgSim::SphereSegment implementation has (using drawImplementation with direct calls to OpenGL) over the use of osg::Vec3Array and osg::PrimitiveSets. Are this direct calls to OpenGL a efficient way of doing things with this type of shape? or do you think that a similar implementation using osg::PrimitiveSets will be equivalent.
Sorry if my question is too basic, but i need to simulate a radar beam and the intersections with the terrain so i thougth of using osgSim::LineOfSight to compute the masked beam volume. Thanks in advance. -- Enrique...
