Problem: Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 初看本题第一印象为递归写法.首先找出终止条件:node == NULL.若未进入递归终止状态,则分左子树和又子树进行递归,最终返回累加最大的值.其代码如下: /*…

在OpenCV2中Mat类无疑使占据着核心地位的,前段时间初学OpenCV2时对Mat类有了个初步的了解,见OpenCV2:Mat初学.这几天试着用OpenCV2实现了图像缩小的两种算法:基于等间隔采样和基于局部均值的图像缩小,发现对Mat中的数据布局和一些属性的认知还是懵懵懂懂,本文对Mat的一些重要属性和数据布局做一个总结. Mat的作用 The class Mat represents an n-dimensional dense numerical single-channel or m…

作为3D世界里最重要的窗口,摄像机的应用就显得很重要,毕竟在屏幕上看到的一切都得用摄像机矩阵变换得来的嘛.论坛上看到了一篇帖子讲非天空盒的背景做法,让我想起其实很多界面合成画面可以用摄像机之间的交互来实现(避开用GUI,效率问题我没尝试过,但是貌似用深度相机比gui好?以后试验下). 首先说下深度相机,就是用2个或者2个以上的相机,设置好参数后自动到屏幕视觉合成的效果,应用上两个方面:1,背景图 2,用户界面. 步骤:1.建立第二个相机,设置 Clear Flags 属性为 Depth Only…

深度偏移用来解决共面情况下出现闪烁的问题 通过给多边形增加一个z方向深度偏移(depth bias,z_bias),使3D空间的共面多边形看起来好像并不共面,以便它们能够被正确渲染.这种技术是很有用的,例如,我们要渲染投射在墙上的阴影,这时候墙和阴影共面,如果没有深度偏移,先渲染墙,再渲染阴影,由于depth test,阴影可能不能正确显示.我们给墙设置一个深度偏移,使它增大,例如z增加0.01,先渲染墙,再渲染阴影,则墙和阴影可以正确的显示. Depth-bias操作在clipping之后进行…
