Only in cauchy distribution are expected value and variance non-exist. By sas programming with SQL and MACRO we solve the fit of frequency distributions of data with these distributions. Meanwhile good-of-fit test is actualized so that the bound of parameters of distribution function is dwindling until the desired accuracy is arrived. The process is executed by the circle of macro.
利用SAS的SQL和MACRO等语句编写了大量的程序,以拟合优度检验结果为标准,不断地变换八种分布的参数变化范围,通过宏程序的不断循环,逐步缩小参数的范围,最后达到预先设定的标准,从而可以发现八种分布中哪几种分布能比较好地拟合给定的实际频数资料,我们再根据拟合优度检验的结果判断出哪种分布拟合实际频数资料最好,最终获得该频数资料的最佳的理论分布函数形式。

In order to draw a photorealistic surface, Bidirectional Texture Functions, a 6D texture function which extends Bidirectional Reflectance Distribution Function to include the self-shadowing, self-occlusion and inter-reflection effects, has been mentioned frequently in recent years. Its main drawback is its massive data size. To solve this, Spatial Bidirectional Reflectance Function techniques compress BTFs into reflectance model parameters. However, SBRDF cannot producethe self-shadowing and self-occlusion effects in real-world surface geometry. This work is aimed to this drawback. I find how self-shadowing and self-occlusion affect the surface by additional physical-based analysis. And I rely on two physical phenomena to divide self-shadowing and self-occlusion into two independent effects. First, self-shadowing is view independent. Second, self-occlusion is independent of lighting direction changes. After these analyses, I use SBRDF and additional self-shadowing and self-occlusion I found to render a photorealistic surface as non-compressed BTFs doing.
为了把物体表面呈现的更真实,六维函数BTFs ( Bidirectional Texture Functions)目前已经被使用的相当频繁,但BTFs的资料量实在太大而没办法直接使用,为了解决资料庞大的问题,传统的SBRDF以逼近光反射模型参数,来达到资料压缩的效果,但是SBRDF对於表面的凹凸所产生的阴影及遮蔽,不能达到逼真的呈现,为了改善这个问题,我们选择从物理方面,找出资料中阴影和遮蔽等属於表面几何的资料并去除,使参数更正确,同时利用两个物理现象去区分阴影及遮蔽为两个互不干涉资料,第一是阴影不会因视角不同而改变,第二是遮蔽不因光线方向不同而改变,经过这些分析,我可以利用SBRDF加上附加的阴影及遮蔽两种独立的效应,来达到彷佛跟未压缩过的BTFs一样的真实绘图。
