View Full Version : glReadPixels and correct depth values with FSAA

07-31-2003, 11:17 PM
Is there any way to get the correct values (via glReadPixels) from the depth buffer when FSAA is enabled?

Enabling 2x 4x and 6x FSAA mode on a Radeon 9700 pro produces some noisy depth maps.

Scaling the buffer size consequently doesn't help anymore.

Is it possible that glPixelTransfer helps?
