Hi,
I'm trying to query GL parameters such as GL_VENDOR, which require an active
graphics context to work. I looked another thread on this forum which explains
how to do it, but it only works for a single-threaded viewer. I'm running the
viewer in multithreaded mode, and am getting crashes due to context issues.
Does anyone have an idea on how to do this?
Thanks
Example code. Usually crashes at the makeCurrent() line:
Code:
//get renderer information
osgViewer::ViewerBase::Contexts contexts;
viewer->getContexts(contexts, true);
contexts[0]->makeCurrent();
std::string vendor = (const char*)glGetString(GL_VENDOR);
Report("Vendor: " + vendor);
contexts[0]->releaseContext();
