[osg-users] performance issues with RTT

Hi, 
 
    I am rendering to Texture and accessing the image to do some preprocessing. So the sequence of operations is -- 
1. Render the scene to an image.
2. Preprocess this image
3. Use a textured quad to display the resulting image
 
-- Even if we remove the preprocessing part completely, no speedup is achieved.
 
Regards
 
Harash

Good morning,

I'm just rendering to texture, no images or pixel reading involved.

Regards,
Steffen
