I would like to change the displayed image within the current refresh.
Example : 2 frames ;
first = display is filled with RED
second = display is filled with GREEN
Now I would like to be able to change within 1 refresh (1 frame)
So the beam of the CRT monitor starts at the top-left of the screen. When the beam is at e.g. 1/3 of the display, I want to change the displayed image but do not want to wait untill the whole frame is created, I want the beam to change real-time, and from now on (1/3) till the end of the image (bottom right) the 2nd frame is already presented.
This would then result in a frame of which 1/3 is RED and the rest of the display is GREEN.
I hope you understand what I mean. If so, is this possible with Cg or CUDA or whatever :)
(I have a FX 4500 card, but this could be changed if necessary)
