Description: 缓冲区分析是指以点、线、面实体为基础，自动建立其周围一定宽度范围内的缓冲区多边形图层，然后建立该图层与目标图层的叠加，进行分析而得到所需结果。它是用来解决邻近度问题的空间分析工具之一。邻近度描述了地理空间中两个地物距离相近的程度。
-Buffer analysis is the basis of a point, line, surface entity, automatically create a buffer around a certain width within polygon layers, and then create the layer and target layer superimposed, analyze and get the desired results. It is used to solve the problem of the proximity of one of the spatial analysis tools. Proximity describes a similar degree of geospatial two feature distance.

Description: C写的计算机图形学算法实例，这是偶对计算机图形学的编程实践，包括画直线、反走样直线、画圆、画椭圆、画矩形、画多边形、矩形填充、多边形填充、3D变换、光照、贴图等，图形均为实时生成，所有算法由本人独立实现，未用任何图形函数库。
由于精力有限，未对原码做任何注释。出于简化编程的考虑，许多地方指定了常数，未做通用处理。解压缩后建立gui16目录，在其下有原代码和工程文件。在gui16下建立release目录，其下有一可执行文件及其所须的位图及模型文件。如在release目录之外执行程序，必须复制所需位图及模型文件。
-Instances of computer graphics algorithms written in C, which is even computer graphics programming practice, including painting line, anti-aliasing straight Circle, painted oval, rectangular painting, drawing, polygon, rectangle fill, polygon fill, 3D transformation, illumination , mapping, graphics are generated in real time, all the algorithms implemented independently by me, not with any graphics library. Because energy is limited, not to make any comments on the original code. Out to simplify the programming considerations, many places specified constant, without making a general-purpose processing. The unzip establish gui16 directory in the source code and project files under it. Establish gui16 under the release directory, under which there is an executable file its required bitmap and model file. Program execution outside in the release directory, you must copy the required bitmap model file.
