    Default Stereo rendering with QOpenGLWidget


    I am in the process of updating from QGLWidget to QOpenGLWidget but can't figure out how to upgrade our stereoscopic rendering code.
    With QGLWidget we simply used glDrawbuffer(GL_LEFT / GL_RIGHT) but this is not working with the new framebuffer backend of QOpenGLWidget.

    Anyone know if it is possible with QOpenGLWidget?

    Default Re: Stereo rendering with QOpenGLWidget

    I think you need to look into QSurfaceFormat and setting a custom format for your QOpenGLWidget. By default, stereo rendering is disabled in the QSurfaceFormat instance embedded in QOpenGLWidget.
