HTC Focus一体机SDK(最新3.0.2)，使用unity开发

vSphere 7的全面支持，从而可以保护在最新VMware版本上运行的虚拟机。必须安装VMware虚拟磁盘开发套件（VDDK）v7才能启用增量备份支持。

现在网上的自动对焦资料比较少，这里简单介绍自动对焦功能实现，为大家提供参考！很多年前的资料了，现在把积分调低。

Focus On 3D Terrain Programming，聚焦3D地形编程技术，英文版（PDF版和CHM版），本书共八章，前四章以翻译完毕，并附在文件的word中，其他章节未完待续。

界面上有很多控件，而且控件焦点利用Tab或者Enter建操作，但是垂直滚动条位置也需要跟随焦点位置移动，方便查看界面遮住的部分。该实例利用递归算法，逐层计算出当前焦点控件所对应于滚动条所在容器的相对Y坐标，给滚动条设置最新位置坐标。

1) Basic concepts of Auto Focus Algorithm 1.1) AF Detection methods There are two focus detection (AF) methods. 1) Distance detection method. 2) Contrast detection method. 1.1.1) Distance detection method The distance detection method is that the camera use AF module for detecting distance for main objects. If the camera is used this AF method, it will not need to use CCD to detect object’s contrast. There are three types of AF modules. 1. Active AF module 2. Passive AF module 3. TTL AF module 1.1.1.1) Active AF module Active AF systems measure distance to the subject independently of the optical system, and subsequently adjust the optical system for correct focus. There are various ways to measure distance, including ultrasonic sound waves and infrared light. In the first case, sound waves are emitted from the camera, and by measuring the delay in their reflection, distance to the subject is calculated. Polaroid cameras were known for successfully applying this system. In the latter case, infrared light is usually used to triangulate the distance to the subject. An exception to the two-step approach is the mechanical autofocus provided in some enlargers, which adjust the lens directly. 1.1.1.2) Passive AF module Passive AF systems determine correct focus by performing passive analysis of the image that is entering the optical system. They generally do not direct any energy, such as ultrasonic sound or infrared light waves, toward the subject. (However, an autofocus assist beam of usually infrared light is required when there is not enough light to take passive measurements.) Passive autofocusing can be achieved by phase detection or contrast measurement.
