![]() ![]() Read primitive data and assemble them into primitives for other stages (e.g. The DX11 graphics pipeline consists of a series of stages shown in Figure 1.Ī description of each stage is summarised in this itemised list: To add tessellation, the graphics pipeline requires three new stages. Primitives refer to the atomic or irreducible objects the system can handle. For instance, calculations for collision detection or soft body dynamics.Ī graphics pipeline is a series of functions that transforms inputs (primitive data such as points, lines or triangles) into outputs for rendering. Improves performance by performing expensive computations at lower frequency (doing calculations on a lower-detail model). ![]() Allows continuous or view dependent details to be calculated on the fly.Lower memory and bandwidth requirements.Benefits of TessellationĪccording to DX11 Tess Docs, the benefits are: Finally, I provide code to run a tessellation visualisation including an interactive widget so you can experiment with the various parameters. This blog post will outline how tessellation fits into the graphics pipeline and how to understand the various parameters needed for tessellation including tessellation factors, partition type, and output domain. Using a low resolution model with a few polygons, tessellation makes rendering high levels of detail possible by subdividing each patch into smaller primitives. Tessellation is a feature that converts a low-detailed surface patch to a higher detailed surface patch dynamically on the Graphics Processing Unit (GPU). Python code is provided to run the visualisation. ![]()
