Hi Robert, Wang Rui, and all I discovered a great gpu memory wasting in ViewDependentShadowMap.
I use CompositeViewer with dynamically adding/removing view, and one global scene graph for all views. ViewDependentShadowMap uses ViewDependentData to store the shadows etc. These Data are stored in a map (ViewDependentDataMap) by CullVisitor. The problem is now, that for each new View that is added to CompositeViewer, a new entry is stored in this map, which is never removed! The removal scenario is not prepared at all. I can add/remove a couple of times a viewer, but then the GPU memory is full and strange effects appear. Right now I have no solution for this. This issue is actutally a serious problem for all view dependent data storage techniques. You have to make sure that when a view is no longer used, all associated data is released aswell!!! Thank you!
