depth buffer values (again)

[thelamberto]

Hi,

Are the values written to the depth buffer interpolated between vertices? Or is one value across the whole polygon used, as was the case with 3D graphics yrs ago?

Cheers.

Interpolation. Z buffers never worked on a per-polygon basis - **z sort** did http://www.opengl.org/discussion_boards/ubb/wink.gif
