Simple OpenGL example for client-mode distortion?

Hi all,

I've been perusing all the wonderful example code posted by the community, and I've found nice working examples for direct mode in OpenGL using GLFW and SDK distortion. Works great. But the examples I've found using client-mode distortion don't seem to function. I'm using 0.4.4 SDK. Anyone know how to get that to work?

Thanks!

    Have you tried this http://federico-mammano.github.io/Oculus-SDK-0.4.4-beta-OpenGL-Demo/?
    It is updated to the 0.4.4 version.

    One of my examples covers client side distortion: https://github.com/jherico/OculusRiftInAction/blob/master/examples/cpp/experimental/Example_X_ClientSideDistortion.cpp

    I haven't updated it in a while so it might need to be tweaked for the latest SDK changes.

    Yes, thank you for posting that code, that was one of the examples I was looking at. Unfortunately on my machine, it changes the desktop color scheme to "Windows 7 basic", then it opens up a window, and then the window stays black and there is nothing displayed on the Rift either. OculusRoomTimyOGL does this, while OculusRoomTiny works fine.

    Should it work fine using direct display?

    I am getting the same result. Visual studio 2010, windows 7. Extended display mode.
    I am also getting a lot of errors in a popup:

    If the call stack is inside DistortionRenderer::EndFrame() then you're not doing client side distortion, you're doing SDK distortion.
