Re: [osg-users] OverlayNode and Uniform Update Callback

Hi osg-users, It seems that the overlay::OverlayData::_camera prevents attached subgraph callback to be called. In future version, is it possible to attach an update callback to the overlay::OverlayData::_camera node, by creating a new function like : void

Re: [osg-users] OverlayNode and Uniform Update Callback

Hi Sergey, My overlay node isn't under a camera node, but is it possible that the overlay projection mecanism is using a camera with subgraph attached to it and so the update traversal doesn't reach the subgraph ?? Best regards, 2011/2/21 Sergey Polischuk pol...@yandex.ru Hi, Alexandre. If

Hi osg-users, I recently tried to attach a fragment shader to a node and set it as an overlay subgraph. My shader is using a uniform that I want to update, so I attached a derived osg::Uniform::Callback to it but this one is never called. When the same node is added to the scenegraph and not
