第8章 图形图像编程MOUSEDRAW

对图像进行逐点计算，并且取最大值和最小值的差值作为该点新的灰度值。 在区别边缘点和非边缘点时，首先确定一个阈值T，若图像中像素点的新 值大于该门限值，则可以初步确定为边缘点，小于T的新值被判断为非边缘点.-Image point by point basis, and taking the maximum and minimum points of difference as the new gray value. Edge in the difference between point and non-edge point, first determine a threshold T, if the image of the new pixel value is greater than the threshold, you can initially identified as the edge point, the new value is less than T have been judged as non-edge point.

能够加载各种3D数据模型，方便研究3D数据，希望喜爱3D的学习者参考，学习。-Be able to load a variety of 3D data models to facilitate the study of 3D data, hope favorite reference 3D learners, learning.

这是一个java代码，能实现导入3D模型并用键盘控制运动。-This is a java code to achieve import 3D models and use the keyboard to control movement.

vrml交互实例。 简单的台灯，可以任意转动，开灯关灯等的交互，门的开关，颜色变换等-vrml interactive examples

图形消隐的生成算法-graphics blanking the Algorithm

图像归一化程序，图像处理领域中广泛应用。

立体显示地形,效果不错，可以实现程序，看立体的地形图，opengl实现-Stereoscopic display terrain, good results can be achieved procedures, see three-dimensional topographic map, opengl achieve
