用于图像处理的一些代码

柱状图，线性图，饼图的绘制，并支持bitmap图形输出-Histogram, linear maps, pie chart rendering, and supports bitmap graphics output

用于vc++图象粗化和细化处理,只能处理256色以下的图象,可连续处理.-for vc images rough and refined, can only handle 256 colors of images, continuous processing.

利用D3D实现了通过高度图生成地形的基本功能，支持地形纹理的载入、程序运行桢数的显示以及在场景中进行漫游（方向键控制移动，w/s键控制俯仰角），适合D3D初学者-D3D realize through the use of a high degree of topographic map to generate the basic functions to support the terrain texture loading, the program shows the number of run-ching as well as in roaming scenarios (the arrow keys to control movement, w/s keys to control pitch angle), suitable for early D3D scholars

3D教程从简单到复杂的进行了入门和提高的讲解，适合于初学者，同时可以step by step地进行学习，比较实用。-3D tutorial from simple to complex and the raising of entry talks, suitable for beginners, but can also step by step to learning more practical.

从LiDAR影像中提取建筑物，最重要的是去除高大的树冠。本项目通过平面拟合去除LiDar影像中的高大树冠，并通过区域生长的方式得到建筑物对象。

这是用VC6.0编写的绘制三次Bezier曲线的程序，使用MFC框架文档视图结构。程序除实现三次Bezier曲线的绘制，还实现了点，直线，圆的绘制，可做为学习计算机图形算法的参考。与其它Bezier曲线绘制程序的不同是，本程序实现了Bezier曲线上型值点的计算显示。程序中编写了Bezier曲线类来完成Bezier曲线的绘制，并能对绘制的曲线数据进行保存与打开。对学习文件操作也有一定帮助。这是我第一次上传源码，有什么不妥之处还请管理员指点。谢谢！-VC6.0 prepared by the cubic Bezier curve drawing procedures, use MFC framework document View structure. In addition to procedures to achieve cubic Bezier curve drawing, but also realized the point, line, round mapping, can be used as learning computer graphics algorithm reference. And other Bezier curves of different procedures, The program of Bezier curve-point value calculations show. Procedures prepared Bezier curves like to complete the Bezier curve drawing, and is able to draw the curve data preservation and open. Operation right to study the documents will also help. This is the first time I uploaded the source code, what is wrong with this manager also requested guidance. Thank you!
