In order to do shadow mapping, I have to enable depth comparisons. Since depth comparison OpenGL state is not wrapped by OpenSG, I have to use glTexParameteri to set it up the same way it is set up in ShadowMapViewport. (I'm not using ShadowMapViewport because I need more flexibility, such as the ability to assign my shadow maps to shaders.)
mTexture->activate((DrawActionBase *)gSimpleSceneManager->getAction(), 0); gives me a core dump because of the first line of TextureChunk::activate: Window *win = action->getWindow(); assigns 0 to win. I try running this code after my window is opened, but before the first frame is rendered. Is there some additional set up that I need to do to make this work? I can't think of anything I'm missing. -- Terry Welsh - mogumbo 'at' gmail.com www.reallyslick.com | www.infiscape.com | www.vrsource.org ------------------------------------------------------- This SF.Net email is sponsored by the 'Do More With Dual!' webinar happening July 14 at 8am PDT/11am EDT.
