[Mesa3d-dev] Bug in z-depth

[Klaus N. <kl...@ma...>]

Hi,

There seems to be a bug in the depth-buffer code. That looks very strong like an rounding-error or something. On
http://www.math.leidenuniv.nl/~klaus/bug.jpg
you can see a screenshot I made. With Mesa-3.2 it looks o.k.

The error was produced by using Crystal-space. I believe it works like this (but I'm not sure): The walls are drawn with activated z-Buffer (but without z-Buffer testing) and afterwards objects are drawn with z-Buffer-test activated.

Greetings

	Klaus
