As others mentioned, z-fighting/stiching occurs even if the camera is not moving. However, when the camera is moving and you're getting z-fighting, it will appear as though the polygons are flickering. This link helped me to understand the depth buffer much better. Here he generates depth values and simulates the different kinds of precision ...

2015年8月7日 · When rendering two overlapping co-planar surfaces, a common issue is "z-fighting", where the renderer can't decide which of the two surfaces is closer to the camera, giving visual artifacts in the area of overlap. The standard solution to this is to give the surfaces a slight offset when designing the model. Is there any other solution?

2019年6月26日 · $\begingroup$ But why there's no z-fighting in the case of identical vertices? As I understand the fragments can be processed in parallel, i.e. primitives A and B are processed at the same time and it's possible that the depths of two neighboring fragments will be calculated for different promitives so they will be colored differently. $\endgroup$

However, you are on the right track. Z-fighting occurs when there is not enough numerical precision to distinguish two "objects" from the scene rendered at the same pixel. In such cases, the two pixels "fight" one another over which one is closest to the camera and flickering occurs. These factors influence how a scene is susceptible to Z-fighting:

2021年5月19日 · Z-fighting is an artifact, essentially a form of "undefined behavior". And how that manifests will be different depending on the situation. You can say that z-fighting might happen, but you can never say that it will unless you know the details of the GPU.

2021年2月2日 · I need to create a decaling into a surface like a mesh, and to avoid Z-fighting I've been using Stencil Buffer to Turn-off depth test and make the decaling over the surface the Stencil Op permits. In fact that decaling fails when we turn the camera in a such way that the viewer has more than one surface point "competing" for the same pixel.

2017年8月10日 · The idea is to better manage Z-fighting by rendering multiple (stacked) frustums with shorter distance between ner and far planes. Each step in the cascade would represent one of those frustums. Using near/far plane clipping, stencil masking and optional vf-culling you can easily render the cascade front-to-back, or each frustum to each own ...

2021年3月11日 · This is basically Z-fighting, but unlike the usual Z-fighting graphics newbies encounter when they don't set the clipping planes right or whatever (and which makes this issue almost ungoogleable), existing hardware definitely does provide some kind of solution to handle this particular case, because this problem does not occur on real GPUs.

2022年10月26日 · 3ds max: Z-fighting when working with Large Objects I had a z-fighting/z-clipping issue with a scene containing some very large objects yesterday in 3ds max. It can be seen in the image below: For some reason downscaling the scene significantly (a ...
