    摘要: Generating a multi-resolution mesh from an original mesh representing a scene or object is achieved by collapsing edges of the original mesh in a first order defined by a surface area error metric to produce a modified mesh, and collapsing edges of the modified mesh in a second order defined by a combination quadric and surface area error metric to produce a multi-resolution mesh. The transition from using the surface area error metric to the combination of the surface area error metric and the quadric error metric occurs when a cost for removing one of the edges from the mesh as determined by the surface area error metric exceeds a threshold. A volume error metric may be used in conjunction with the surface area error metric in collapsing edges of the mesh to allow an edge collapse only when the volume error metric for the edge indicates collapsing the edge will not substantially alter the shape of the mesh.

    摘要: Apparatus, systems and methods for optimized frustum clipping via cached clip vertices are disclosed. For example, a method is disclosed, the method including generating a clip vertex for a leading edge of a triangle of a triangle strip or fan, indicating that the leading edge is shared with an adjacent triangle of the triangle strip or fan, and in response to the indication, using the clip vertex as a clip vertex of a trailing edge of the adjacent triangle in the triangle strip or fan. Other implementations are disclosed.
