Hi,
I am looking into some post rendering effects by drawing my scene, saving it to a texture, clearing my scene, and then mapping the created texture to a full screen sized quad.
The only problem is that the texture quality is less of that of the original image. The final result (without any effects) is blurier than the original.
I am using glCopyTexImage2D and my viewport size does not change.
Is there any way around this so that my image stays sharp?
Thanks
