Hello, As I've been playing with shaders in OSG, I've tried to get the shader info log so I can export it directly to a file (largely because it doesn't want to show up in the console when I have a GLSL compilation error).
In any case, I've pieced together several snippets of code across a few posts from the forum, but to no avail. The code: Code: osgViewer::ViewerBase::Contexts* c = new osgViewer::ViewerBase::Contexts(); viewer.getContexts(*c); unsigned int contextID; osg::ref_ptr<osg::State> stat; for (osgViewer::ViewerBase::Contexts::iterator itr=c->begin(); itr!=c->end(); ++itr) stat = (*itr)->getState(); contextID = stat->getContextID(); osg::ref_ptr <osg::Geode> pass1 (dynamic_cast<osg::Geode *> (FindNode(root, "root_geodeShaderGeometry1")->getFirst())); osg::ref_ptr <osg::Program> sh1 (dynamic_cast<osg::Program *> (pass1->getStateSet()->getAttribute(osg::StateAttribute::PROGRAM, 0))); std::string log; osg::Shader* shader = sh1->getShader(0); shader->compileShader(*(stat.get())); bool logFound = shader->getGlShaderInfoLog(contextID, log); if (logFound) std::cout << log; I can retrieve my shader programs fine (I have 3), but i get an unhandled exception (access violation) at 0xcdcdcdcd when I try to call compileShader or getGlShaderInfoLog. That tells me the problem isn't with my parameters, but with accessing the shader object itself. I'm sure it's something simple that I've overlooked, and I imagine it's been covered in another post somewhere, but since my knowledge of OSG overall is pretty much limited to what I've tried to implement, the solution eludes me. Any thoughts? ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=34726#34726 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
