[osg-users] new ref_ptrs in Callbacks

Hi, Let me preface this by saying that I know how to make my code do what I want it to, so this question is of low importance and arises from doing something that could(should?) be considered silly- dynamic allocation within a callback operator method when the callback can have a class member

Re: [osg-users] osg camera location

Hi Ricky, I sounds like your confusing things. The 3d scene is world coordinates, the transforms in the scene graph place the subgraphs in world coordinate, these transforms (if any) provide the model part of the OpenGL modelview matrix. The osg::Camera then provides the view matrix that moves

Hi Roman, There are many ways to do this, how you do it will depend on what you find more convenient... Ulrich's solution is one. You could create two Geodes with different textures (summer/winter) that share the same geometry. Or you could have two Geometry objects that share the same
