The real-time re-projection cache


I've added real-time reprojection cache to the engine. For SSAO looks like a winner technique because it uses expensive shader. Red pixels aren't re-computed because they are stored in an auxiliar buffer to be reprojected.

When camera moves slowly or it's stopped the FPS reaches to infinite and beyond... :p

Hi, I think there is a technique that is similar to what you are doing. See Accumulative Screen Space Ambient Occlusion (ASSAO)

Thanks, I've been seen that. But I use the re-projection cache only in order to avoid duplicate pixel shader calculations between frames. Anyway... It's a nice technique.

Simply by saying 'There is no god apart from God, and Muhammad is the Messenger of God.' By this declaration the believer announces his or her faith in all God's messengers, and the scriptures they brought.
