用VC编写的圆弧样条，B样条曲线的绘制程序，在单文档中输入任意点，绘制出点间的圆弧样条曲线与B样条曲线-VC prepared by the arc-like, B-spline curve mapping procedures in a single document input arbitrary point and draw points of the circular spline curves and B-spline curves

图像的点运算主要用来改变图像的灰度分布范围；点运算的最大特点是输出像素值只与当前输入像素值有关，本文主要介绍利用灰度直方图查看图像信息，了解各种灰度变换公式，掌握灰度变化实现方法。

The Hammersley and Halton point sets, two well known low discrepancy sequences, have been used for quasi-Monte Carlo integration in previous research. A deterministic formula generates a uniformly distributed and stochastic-looking sampling pattern, at low computational cost. The Halton point set is also useful for incremental sampling. In this paper, we discuss detailed implementation issues and our experience of choosing suitable bases of the point sets, not just on the 2D plane, but also on a spherical surface. The sampling scheme is also applied to ray tracing, with a significant improvement in error.
