摘要： Generating a modified mesh by simplifying an original mesh representing a scene or object is achieved by collapsing edges of the original mesh in an order defined by an error metric to produce the modified mesh. Determining the error metric includes selecting an edge of the mesh, performing an edge collapse operation for the selected edge, computing at least one distance from a plane of each updated face of the mesh to a position of a vertex removed during the edge collapse operation, selecting a maximum distance of the computed distances as the error metric for the edge collapse operation for the selected edge, and restoring the collapsed edge to the mesh.

摘要： A method of producing a multi-resolution mesh is provided. A vertex array and a face array are constructed, wherein the vertex records and face records are ordered in the respective arrays by resolution. These arrays therefore comprise ordered vertices and faces to be added or removed for each incremental change in resolution. A vertex update record associated with each vertex contains face update records which specify what existing faces must be updated when adding or removing the vertex, and contains a new faces record indicating the number of faces from the face array to be added to or deleted from the mesh when adding or removing the vertex.

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.
摘要翻译：通过表示场景或对象的原始网格生成多分辨率网格是通过以表面积误差度量定义的第一顺序折叠原始网格的边缘来产生修改的网格，并将修改网格的边缘折叠在一个通过组合二次曲面和表面积误差度量定义的第二阶，以产生多分辨率网格。当从表面积误差度量确定的去除网格中的一个边缘的成本超过阈值时，会发生从使用表面积误差度量到表面积误差度量和二次误差度量的组合的过渡。体积误差度量可以与网格的折叠边缘中的表面积误差度量结合使用，以允许仅当边缘的体积误差度量指示折叠边缘将基本上不改变网格的形状时边缘折叠。

摘要： Embodiments of techniques and systems for execution of code with multiple page tables are described. In embodiments, a heterogenous system utilizing multiple processors may use multiple page tables to selectively execute appropriate ones of different versions of executable code. The system may be configured to support use of function pointers to virtual memory addresses. In embodiments, a virtual memory address may be mapped, such as during a code fetch. In embodiments, when a processor seeks to perform a code fetch using the function pointer, a page table associated with the processor may be used to translate the virtual memory address to a physical memory address where code executable by the processor may be found. Usage of multiple page tables may allow the system to support function pointers while utilizing only one virtual memory address for each function that is pointed to. Other embodiments may be described and claimed.
