Abstract: When rendering a region of a three-dimensional object represented by a base set of polygon vertices in a graphics processing pipeline, a first processing stage uses meta-information representative of the surface relief of the region of the three-dimensional object to determine whether to generate a set of additional polygon vertices over the region of the three-dimensional object, and generates the additional set of polygon vertices (when this is deemed necessary). A second processing stage then uses information representative of the surface relief of the region of the three-dimensional object to modify the positions of one or more of the polygon vertices, before the vertices are assembled into primitives that are then rasterised and rendered.

Abstract translation: 当在图形处理流水线中渲染由多边形顶点的基本集合表示的三维对象的区域时，第一处理阶段使用表示三维对象的区域的表面浮雕的元信息来确定是否 在三维对象的区域上生成一组附加的多边形顶点，并生成附加的多边形顶点集合（当需要时）。 然后，在将顶点组装成然后被光栅化和渲染的图元之前，第二处理阶段使用表示三维对象的区域的表面浮雕的信息来修改一个或多个多边形顶点的位置。
