OpenGL Texture Probelm

Hello!

I'm running TAO with .NET 2. It works fine but I have some problems with fast
re-texturing. I'm getting updates form a VNC-Server a few times per second as an
.NET Bitmap.

In that case, I update the Texture with glTexSubImage2D() and rerender the
scene. But it doesn't work very well, because the texture flickers every few
seconds, that means the object is getting white for a few milliseconds and then
 changes to the new texture.

I use a flag to supress rendering while texture-update is running, but it
doesn't solve the problem.


Do you know a solution?


thanks,
Jens

Hi,

I have the impression that you are using multiple threads. If that's true,  
then I think the problem is related to that, since you cannot use the same  
opengl context from different threads.

Greets,
