    摘要： Systems and methods for a tessellation are described. The tessellation unit is configured to determine a number of points that reside along a first edge of a first ring within a domain, determine a first set of coordinates for a first portion of the points that reside along the first edge of the first ring within the domain, and determine a second set of coordinates for a second portion of the points that reside along the first edge of the first ring within the domain based on the first set of coordinates for the first portion. The tessellation unit is also configured to stitch points that reside along the first edge of the first ring with points that reside along a second edge of a second ring to divide the domain into a plurality of primitives that are mapped to a patch.

    摘要： A method, computer program product, and system are provided for processing data in a graphics pipeline. An embodiment of the method includes processing one or more vertices of a geometric primitive with a vertex shader function and generating new primitive information for the one or more processed vertices with a geometry shader function. The geometry shader function receives one or more processed vertices from the vertex shader function and emits a single vertex associated with the new primitive information. Each emitted vertex from the geometry shader function can be stored in a memory device. Unlike conventional graphic pipelines that require a memory device for data storage during the vertex and geometry shading processes, the present invention increases efficiency in the graphics pipeline by eliminating the need to access memory when the vertex and geometry shaders process vertex information.

    摘要： The present invention addresses the problem of describing an arbitrary object (up to user-defined limits) given a set of triangles with vertex normals describing the object. A novel method of successively merging traingles into larger and larger patches to compute a set of "as-few-as-possible" Bezier patches is presented. This method is not only applicable to arbitrary objects, but also aims at producing as few patches as possible depending on the geometry of the input object. Also presented are methods to enforce C.sup.0 - and C.sup.1 -continuity between a pair of patches B.sub.L (s,t) and B.sub.R (s,t), placed arbitrarily. The methods perturb the appropnate control points to achieve geometric continuities. For C.sup.0 -continuity the area of the hole between the patches is minimized by formulating the area as a series of linear programs, where the continuity has to be enforced across the adjacent boundary curves B.sub.L (1,t) and B.sub.R (0,t). Similarly, to enforce C.sup.1 -continuity the hole-area in tangential space is minimized.

    摘要翻译： 本发明解决了给定一组具有描述对象的顶点法线的三角形的任意对象（直到用户定义的限制）的问题。 提出了一种将串联连续并入更大和更大的补丁以计算一组“尽可能少的”贝塞尔补丁的新颖方法。 该方法不仅适用于任意对象，而且还可以根据输入对象的几何形状尽可能少地生成补丁。 还提出了在任意放置的一对补丁BL（s，t）和BR（s，t）之间执行C0-和C1-连续性的方法。 这些方法扰乱了适当的控制点来实现几何连续性。 对于C0连续性，通过将区域配置为一系列线性程序，必须在相邻的边界曲线BL（1，t）和BR（0，t）之间执行连续性，使得补片之间的孔的面积最小化， 。 类似地，为了强制C1连续性，切向空间中的孔面积被最小化。
