这个类库可以处理BMP、GIF、PCX、TGA、JPG、TIF格式的图像文件，而且具有图像点处理、图像区域处理的功能，你所要做的只是调用函数而已，不必清楚这些图像文件的内部格式。-the library can handle BMP, GIF, PCX, TGA, JPG, TIF format image files, and images with point processing, image processing functions regional, you have to do it is the function call and not aware of these images document the internal format.

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.
