A phenomenon in three-dimensional rendering where two or more primitives have similar values in the z-buffer, causing flickering as one is displayed varyingly behind or in front of the other.
Z-fighting is a phenomenon in 3D rendering that occurs when two or more primitives have similar values in the z-buffer. It is particularly prevalent with coplanar polygons, where two faces occupy essentially the same space, with neither in front. Affected pixels are rendered with fragments from one polygon or the other arbitrarily, in a manner determined by the precision of the z-buffer. It can also vary as the scene or camera is changed, causing one polygon to "win" the z test, then another, and so on. The overall effect is a flickering, noisy rasterization of two polygons which "fight" to color the screen pixels. This problem is usually caused by limited sub-pixel precision and floating point and fixed point round-off errors. Z-fighting can be reduced through the use of a higher resolution depth buffer, by z-buffering in some scenarios, or by simply moving the polygons further apart. Z-fighting which cannot be entirely eliminated in this manner is often resolved by the use of a stencil buffer, or by applying a post transformation screen space z-buffer offset to one polygon which does not affect the projected shape on screen, but does affect the z-buffer value to eliminate the overlap during pixel interpolation and comparison. Where z-fighting is caused by different transformation paths in hardware for the same geometry it can sometimes be resolved by requesting that the hardware uses invariant vertex transformation.
