What is directx 11 tessellation?

The Direct3D 11 runtime supports three new stages that implement tessellation, which converts low-detail subdivision surfaces into higher-detail primitives on the GPU. Tessellation tiles (or breaks up) high-order surfaces into suitable structures for rendering.

Does tessellation improve performance?

Tessellation is a way that you can save memory and bandwidth but at the cost of GPU performance. Why you should use tessellation: Tessellation with displacement maps significantly reduces memory bandwidth for animated or multi-instance objects in the scene.

What does the tessellation control shader do?

The Tessellation Control Shader (TCS) determines how much tessellation to do (it can also adjust the actual patch data, as well as feed additional patch data to later stages). Therefore, the TCS is primarily responsible for ensuring continuity across patches.

What is Surface tessellation?

A tessellation or tiling is the covering of a surface, often a plane, using one or more geometric shapes, called tiles, with no overlaps and no gaps. In mathematics, tessellation can be generalized to higher dimensions and a variety of geometries.

What is tessellation factor?

The tessellation factor at max would basically force your mesh to be at the highest resolution. If you have a lower tess factor, you may get 10m or 20m points even though you’re settings loaded a 5m mesh. This would only happen though if they 5m mesh tiles was far enough away.

Is tessellation a demanding?

Generally speaking, tessellation is a nice addition to games but it’s not mandatory for gamers. Under typical circumstances, visual differences are hard to spot, so you can safely disable it to help boost performance.

What are the minimum required shaders for rendering?

The OpenGL-required minimum is 8 for fragment and compute shaders, and 0 for the rest. This means implementations may not allow you to use image variables in non-fragment or compute stages.
