Hello, what is the policy regarding vertex and geometry shaders in a cluster environment? With vertex and geometry shaders, OpenSG loses some control over the geometry as the user is able to transform the geometry arbitrarily beyond the standard model-view-projection transformation.
Obviously, frustum culling and ray-cast picking via IntersectAction will not work as expected since OpenSG works on the untransformed bounding volume. A solution for picking would be to use Color Picking with an ID-Buffer as demonstrated by the idbuffer.cpp example. Are there any other areas within OpenSG that exhibit problems with geometry that is heavily transformed by vertex/geometry shaders? Especially in a cluster environment like a CAVE, will you have to expect display artefacts? Thank you for your answer.
