离散性是采样点均匀分布的一种标量度量，本文在计算机图形学采样问题中进行了讨论。几个抽样策略和他们的差异特性进行了检查。建立了图像误差与用于产生图像的采样模式的差异之间的关系。将偏差的定义推广到非均匀抽样模式。CR
Discrepancy, a scalar measure of sample point equidistribution, is discussed in the context of Computer Graphics sampling problems. Several sampling strategies and their discrepancy characteristics are examined. The relationship between image error and the discrepancy of the sampling patterns used to generate the imaqge is established. The de nition of discrepancy is extended to non-uniform sampling patterns. CR
