摘要：Methods and computer-storage media are provided for rendering three-dimensional (3D) graphics by tessellating objects using novel structures and algorithms.
Rendering utilizing “patches,” configurable functions that include a specified number ofcontrol points, allows for computation on a per-patch or per-control-point basis, inaddition to traditional per-vertex, per-primitive, and per-pixel methods. This produces anumber of advantages over previous tessellation methods, including the reuse ofcomputations across existing vertices and the ability to process at a lower frequency. Theoperations to compute points are simplified in order to optimize system resources usedin the process. Transitions from un-tessellated to tessellated objects are smootherutilizing the present invention, while developers have more flexibility in the level of detailpresent at different edges of the same patch. Detail within a displacement map also canbe increased without negative effects associated with previous systems and methods.
