Abstract: This disclosure describes techniques for rendering a plurality of primitives that includes at least two different types of primitives during the execution of a single draw call command. This disclosure also describes techniques for rendering a plurality of primitives using tessellation domains of different tessellation domain types during the execution of a single draw call command. The techniques of this disclosure may, in some examples, reduce the complexity and processing overhead for user applications, reduce the number of times that the rendering state of the graphics rendering pipeline needs to be switched during the drawing of a graphics scene, and/or reduce the number of times that shader programs need to be reloaded into different processing stages of a graphics pipeline during the rendering of a graphics scene.

Abstract translation: 本公开描述了在执行单个绘制调用命令期间渲染包括至少两种不同类型的图元的多个图元的技术。 本公开还描述了在执行单个绘制调用命令期间使用不同镶嵌域类型的镶嵌域渲染多个图元的技术。 在一些示例中，本公开的技术可以降低用户应用的复杂性和处理开销，减少在图形场景绘制期间需要切换图形呈现管线的渲染状态的次数，和/或 减少在渲染图形场景期间着色器程序需要重新加载到图形管道的不同处理阶段的次数。

Abstract: A tessellation unit of a graphics processing unit (GPU) determines domain coordinates for vertices of a received primitive. The tessellation unit outputs the determined domain coordinates for the vertices. The tessellation unit further determines that a domain type for the received primitive is not one of tri, isoline, or quad domain, and outputs information indicative of a graphical feature associated with one or more of the determined domain coordinates when the domain type is not one of the tri, isoline, or quad domain.
