Z-Fighting is an effect that happens in 3D scenes when two
co-planar surfaces share similar values in the z-buffer which leads to flicking
and visual artifacts during the rendering process due to conflicting
order of rendering the surface. However in 3D level design, scenes created
by the tools can be complex, in which level designers can inadvertently
place co-planar surfaces that would be susceptible to z-fighting. Level
designers typically notice the z-fighting artifact through visual inspection
through the usage of a 3D walkthrough test on the scene which is
time-consuming and easy to miss. To solve the issue, a proposal of a zfighting
detection system for level design tools is proposed to streamline
the process of detecting potential hotspots where z-fighting conflicts may
occur from co-planar objects.
