I'm wondering if there is a robust and relatively noninvasive way of averaging previous frames with the current frame, perhaps with a little jitter, so that you get a sort of psuedo antialiasing effect while sitting, and a motion blur effect when moving.
I think I read somewhere that the ShadowOfTheColossus game used a similar approach.
I tried glAccum() as the obvious place to start, but as usual it kills any program I've ever tried to use it with, and with any hardware throughout the years.
Logically it seems like glAccum would be the ideal avenue for this sort of stunt (if I understand the process correctly)
The idea of sort of reusing frames this way sounds like something you might think you would see in many games. Is there, or should there be, a draw back to such an approach, and how do people do it with opengl provided it actually is a sort of industry standard approach to frame rending?
My apologies for approaching this idea so lazily, but its really only a fleeting curiosity that I just happened to feel like trying out today.
