Cannot render Backface

[zateyev]

Hi,

I implemented a two-pass ray casting in OpenGL, and I wanted to port my implementation into Equalizer. However, I have difficulty in rendering the backface. I can generate the front face cube, but back face gives me a black screen with messages. The approach I'm using is based on the tutorial here.

Front Face

Back Face

I use the eqHello example provided by Equalizer. Am I missing something or could you please tell me where I'm doing it wrong?

I also provided my code implementation here.

Thanks and looking forward to hear from you.

On a first glance, I see nothing wrong. The second image look like something is drawn, but the color buffer is garbage from the existing framebuffer. Unfortunately I won't have time to look into this the next week. I would suspect some difference in GL state between the versions.

The key code message has surely nothing to do with it.
