I'm trying to pre-load some models that need their texture to be rescaled. Looking at earlier post I saw suggestions about using a Camera pre-draw callback that uses the GLObjectsVisitor to compile everything...but I can't find out exactly how to do this.
By now, here is what I did: 1) created a class derived from DrawCallback 2) before entering the rendering loop, I get a camera from the viewer and set a preDrawCallback using the newly created class But now what I'm missing is how to use GLObjectsVisitor, I guess that I must use it inside the override for DrawCallback::operator()(osg::RenderInfo& renderInfo) const; but how? As far as I understand from renderInfo I can get the camera and, by doing so inside such a callback, I'm sure to get the camera for the current context, but how do I apply the GLObjectsVisitor at this point? Thank you very much for your help. Alessandro
