Hello, everyone. To achieve my goal in my OSG application, I need the shapes that are on the screen to change their colors when selected by mouse picking. All the shapes that are on the screen, from the class "Sphere", for instance, have the following pattern of inheritance (in which the symbol '->' means that the following class inherits the methods from the previous one):
osg::MatrixTransform -> Primitive -> Sphere With this, I mean that a sphere created is a matrix that has a geode connected to it, which carries the shape's information on a shapedrawable. So, how do I change the color of a shape, which is an osg::MatrixTransform object, if this attribute is only accessible on osg::ShapeDrawable objects? Thanks very much. Renan M Z Mendes
