Re: [osg-users] Unit tests

Hi Vincent, Delta3D uses cppunit, and we've been using this library as well for our unit tests. It offers nice macros to run and check the tests, makes it easy to launch a whole suite of tests or only a part of them (via namespace) and optionally prints results on an xml file, besides the

Hello Danny, I'm trying to move my camera forward and backward as the event of up/down key. You're on the right track with your subclass of osgGA::GUIEventHandler. This class's handle() can set the camera's view matrix using camera-setViewMatrix() (or the convenience

Hi CG, I've uploaded a video http://www.youtube.com/watch?v=X4xgFzaBBWs to show the problem I'm facing when rendering a geometry. Any advices? Yes, that's most definitely z-fighting. Try moving the geometry higher above the terrain, or setting the near and far planes as close to each other

Re: [osg-users] setUpdateCallback fails under slave-camera

Hi Robert, I'm picking up this somewhat outdated topic since we are having a similar problem. We need to render some of our geometry with a separate depth buffer because of precision issues: In the first pass, we are rendering a very large landscape that was created using VirtualPlanetBuilder.
