![]() Tessellation isn’t the hot new graphics technology it once was-leave that to ray tracing-but it’s still one of the most important technologies used in games to make their virtual worlds feel more real and alive. SapphireNation’s in-depth analysis shows that effects such as HDR and depth of field can have a far greater impact on performance than anything tessellation entails. Head-to-head quiz on popular games using tessellation GTA Vsuggests the impact is minimal, dropping only a few frames per second even in the most challenging situations with significant in-game tessellation. With Tessellation’s ability to overwhelm visuals, what impact does it have on games, if not always to the same extent? Does enabling tessellation in your chosen game lower your frame rate? This makes it much easier for the developer to create detailed scenes using tessellation. Creating a low detailed model with a high quality texture and the displacement map applied to it is much easier than creating a very detailed model to go with the texture. Not in terms of dollar cost, but in terms of system resources. The ultimate reason is that it’s easier and cheaper. So why do we use tessellation charts instead? There’s no reason why such a 3D visual effect can’t be achieved by building a model of this depth and scale and texturing it appropriately. While the tessellation effect in tests like Unigine Heaven is nice, it’s certainly not surprising, especially in 2020. That’s extreme – no game developer would rely solely on tessellation for such an important visual feature – but it shows how tessellation can have an effect under the right circumstances. In the image above, you can see the stairs, which were previously a flat ramp with a staircase-like texture, transformed into a 3D representation of a tiled staircase. Although typically used in conjunction with other visual techniques, the Unigine Heaven simile is a clear reminder of the power of tessellation under the right conditions. ![]() Tessellation sets and landmarks use it to create much deeper objects and landscapes. It’s actually a texture that can store information about its height – how far it protrudes from its base. Tessellation is special because it is combined with displacement mapping (which is slightly different from bump mappings). Maybe add a layer of detail to an image that doesn’t otherwise exist, but artistic texturing alone can do that. This alone does not produce a greatly improved effect. Tessellation allows these triangles to be greatly divided, so each halving (or doubling, depending on your perspective) creates finer detail because edges are less pronounced and patterns are more nuanced. Introduced with DirectX11, tessellation itself is a method of increasing detail in a scene by subdividing the triangular meshes that make up objects and characters in game worlds. It can also make the development process easier.
