1. Z-fighting

   Z-fighting, also called stitching, or planefighting, is a phenomenon in 3D rendering that occurs when two or more primitives have very similar distances to the camera. This would cause them to have near-similar or identical values in the z-buffer, which keeps track of depth. This then means that when a specific pixel is being rendered, it is ambiguous which one of the two primitives are drawn in that pixel because the z-buffer cannot distinguish precisely which one is farther from the other. If one pixel was unambiguously closer, the less close one could be discarded. 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 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. The more z-buffer precision one uses, the less likely it is that z-fighting will be encountered. But for coplanar polygons, the problem is inevitable unless corrective action is taken. As the distance between near and far clip planes increases, and in particular the near plane is selected near the eye, the greater the likelihood exists that z-fighting between primitives will occur. With large virtual environments inevitably there is an inherent conflict between the need to resolve visibility in the distance and in the foreground, so for example in a space flight simulator, if a distant galaxy is drawn to scale, the viewer will not have the precision to resolve visibility on any cockpit geometry in the foreground (although even a numerical representation would present problems prior to z-buffered rendering). To mitigate these problems, z-buffer precision is weighted towards the near clip plane, but this is not the case with all visibility schemes and it is insufficient to eliminate all z-fighting issues.

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.
