Boundary transition region stitching for tessellation |
摘要 |
A system and method for stitching a boundary transition region of a patch produces a graphics primitive topology for the boundary transition region of the patch. A first number of vertices is computed for an inside edge of the boundary transition region using a first tessellation level of detail (LOD) of the inside edge. A second number of vertices is computed for an outside edge of the boundary transition region using a second tessellation LOD of the outside edge. A portion of the first number of vertices and the second number of vertices are merged based on a stitching pattern to produce a set of vertices for the boundary transition region. The set of vertices is stitched to produce an ordered list representing the graphics primitive topology. |
