This will in most likely be an issue with your integrated graphics chip and driver set and not directly OSG issue
I would recommend that you upgrade your drivers if they are available , this may help it may not as integrated chips while improving still fall way behind in Opengl capabliltyy than dedicated graphics cards Gordon Product Manager 3d __________________________________________________________ Gordon Tomlinson Email : gtomlinson @ overwatch.textron.com __________________________________________________________ -----Original Message----- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of hui Sent: Thursday, March 12, 2009 4:33 PM To: osg-users@lists.openscenegraph.org Subject: [osg-users] DrawImplementation issue with Intel video card. Hi, I meet a problem in function drawImplementation(osg::RenderInfo& renderInfo) const Actually the code works find with nvidia and ati video card, just when I run it in intel 965GM, it get problem. Here is the code: void SubmeshDrawable::drawImplementation(osg::RenderInfo& renderInfo) const { osg::State& state = *renderInfo.getState(); //bind the VBO's state.disableAllVertexArrays(); bool initializedThisDraw = false; if (!mInitalized) { InitVertexBuffers(state); mInitalized = true; initializedThisDraw = true; } -----........................................ // notice when first time run, then mInitalized is assigned as true, and it keeps as true in nvidia or ati video card. // But in Intel card, the value of mInitalized will change back to false again when enter the function at second time, and keep in this way until the VBO crashed. Any reason for that? Thanks a lot.
