Method and system for interpolating level-of-detail in graphics processors
Abstract:
A method determining LOD values for a geometric primitive, in accordance with one embodiment of the present invention, includes accessing a plurality of geometric parameters of a vertex. An LOD value for a vertex is calculated as a function of the plurality of parameters of the vertex in a setup module. In a raster module an LOD value for a pixel is interpolated as a function of the LOD value of the pixel corresponding to the vertex and a view distance of the non-vertex pixel.
Abstract(Chinese):

根据本发明的一个实施例，确定几何图元的LOD值的方法包括访问顶点的多个几何参数。 根据设置模块中的顶点的多个参数计算顶点的LOD值。 在光栅模块中，将像素的LOD值作为与顶点对应的像素的LOD值和非顶点像素的视距进行插值。
