Hi guys, I have a scene setup problem that I am sure is easy to solve with OSG if someone could help me properly understand the use of node masks. Consider this scene:
Root /\ / \ ______/ \______ / \ DecorateGroup RenderGroup \ | \ /\ \ ___/ \____ \ / \ \___ PAT Subgraph with more objects /\ / \ GeodeA GeodeB I have a group of objects that I want to render, all children of the RenderGroup. Some of these objects I want to decorate by drawing the same geometry with a different stateset that enables cartoon outlines when I pick it. Now I want to add a subgraph to this decoration, but I only want to allow some of the nodes within the subgraph to be affected by the stateset in DecorateGroup. For example, if I attach PositionAttitudeTransform PAT to DecorateGroup, I only want GeodeA to be decorated. I think one way would be to protect attributes that are overridden by the stateset in DecorateGroup, but I don't want to have to do that for all objects that might be picked. I expect this can be done with node masks, but I am not sure how to set up a node mask so that GeodeB is drawn only once when RenderGroup is traversed and not drawn when DecorateGroup is traversed. I would be really grateful if someone could explain this to me. Thanks!
