摘要： A tessellation method includes assigning a tessellation factor to each of a plurality of points in a patch and generating, in the vicinity of a first point of the plurality of points, at least one new point based on a first tessellation factor assigned to the first point. The at least one first new point corresponds to the first point.

摘要： A method of operating a graphics processing unit includes determining, based on input data, whether to perform a tiling operation before or after a tessellation operation and performing the tiling operation according to the determination result. Performing the tiling operation after the tessellation operation if the input data is not a patch, and if a geometry of the patch is at the out-side of a convex hull defined by control points of the patch. Performing the tiling operation after the tessellation operation if a geometry of a tessellated primitive corresponding to the patch changes according to a shading operation.

摘要翻译： 操作图形处理单元的方法包括：基于输入数据确定是否在细分操作之前或之后执行拼贴操作，并根据确定结果进行拼贴操作。 如果输入数据不是补丁，则在细分操作之后执行平铺操作，并且如果补丁的几何形状位于由补丁的控制点定义的凸包的外侧。 如果与补丁相对应的镶嵌图元的几何形状根据着色操作而变化，则在细分操作之后执行平铺操作。
