Given two rectangles and the coordinates of two points on the diagonals of each rectangle,you have to calculate the area of the intersected part of two rectangles. its sides are parallel to OX and OY . Input The first line of input is 8 positive numb…

轮廓提取相对容易,只需在2.5D渲染视角下,导出模型的顶点坐标以及基于视角的消隐后的三角形面,将三角面投影后合并就可得到轮廓,轮廓坐标基于2.5d图的基准坐标换算就得到.提取轮廓的在我另外一篇文章中有试用的插件,基于3dmax2013的. 轮廓遮挡部分的剔除,如果自动完成的话,效率特别低. 要处理一个模型,原则上要对模型可见面上的点沿视线方向引出直线,与相关模型的可见面做相交运算(在目前2.5D的视角下,模型包围盒的最小y值小于待处理模型都要计算),有交点的模型就用该模型的轮廓来裁剪待处理模型的…

基于3dmax2013的2.5d渲染插件,demo版,需要的和感兴趣的可以试用,这是百度网盘地址:http://pan.baidu.com/s/1c0mYY7e 插件主要功能,按层级对3dmax场景进行瓦片渲染,生成256×256的图片,供webgis相关地图展示引擎使用. 插件还包括了基于瓦片渲染投影的建筑物二维轮廓线提取. 联系方式:helperwyp@gmail.com…

题目地址: http://poj.org/problem?id=1314 题意: 给出一串的点,有些点可以构成正方形,请按照字符排序输出. 因为这道题的用处很大, 最近接触的cv 中的Rectangle Detection 中就有方法使用到了这个算法. 但实际中使用的算法还是暴力. 不过因为数据点较少,可以直接快排之后,再来个迭代,就得到答案了 #include <cstdio> #include <iostream> #include <cstring> #inclu…

Description We are given a figure consisting of only horizontal and vertical line segments. Our goal is to count the number of all different rectangles formed by these segments. As an example, the number of rectangles in the Figures 1 and 2 are 5 and…

ZBrush不仅对3D行业进行了改革.让艺术家感到无约束自由创作的3D设计,同时它还是一个强大的绘画程序!基于强大的Pixol功能,ZBrush®将数字绘画提升到一个新的层次.如下图所示,插画功能主要应用在2.5D笔刷上. 查看更多内容请直接访问:http://www.zbrushcn.com/jichu/2-5d-painting.html 下图所示为大师ken Brilliant用ZBrush插画功能绘制的作品. 其他2D程序中的像素只包含颜色和位置信息,ZBrush的Pixol包含了颜色,…
