Qt Demo OpenGL->Framebuffer Object 2 doesn't work



  • Hi guys,

    I just started to learn opengl stuff and try to run the demo provided by QT. The example 'texture' and 'framebuffer object' all work fine, while 'framebuffer object 2' only shows a black screen. My machine: windows 7 64bit, AMD Athlon II X4 645 processor 3.1GHz, 4GB RAM, Graphic card Nvidia GeForce 6150SE nForce 430/integrated/SSE2
    Opengl version 2.1.2, glsl version 1.20. The graphic card is a little weak but it supports OpenGL 2.1 and I think it should be strong enough to run the demo program. I updated the GPU driver to the latest version from nvidia website.

    Anyone has any idea? Thanks in advance.



  • I debug the code and found it's because the binding of framebuffer object failed. Anyone can tell me the possible reason or how to avoid this problem? Thanks!



  • Hi, WonderBen. I know it's been some time since you have posted your problem, but have you found a solution? I've just started learning openGL; when I run the "FrameBufferObject2" example, Qt gives a segmentation fault error when the QGLFramebufferObject object is dynamically allocated. I tried some other examples from the "opengl" examples directory and for those the compilation works fine. Thus, i don't think the error comes from the configuration on my laptop. Any ideas are apprecated, thank you!
