增强现实游戏开发

　　基于位置的增强现实（AR）游戏的鼎盛期已经来到了。该技术其实在几年前就已经出现，但直到《Pokemon Go》（口袋妖怪GO）这款具有变革意义的游戏的发布才催化了整个市场，激发出大量的需求。无论是新手还是老兵，现在正是将他们各自的好点子转化为AR移动游戏，迎合市场需求的好时机！
　　基于位置的AR游戏题材引入了一个全新的平台和技术挑战，这本《增强现实游戏开发（影印版 英文版）》可以帮助你简化这些难题并展示如何将你的游戏受众大化。
　　《增强现实游戏开发（影印版 英文版）》将带领你构建一个基于位置的AR游戏，在这个过程中会涉及到一些核心技术概念：GIS基础、移动设备GPS、绘图、Unity地图纹理、移动设备摄像头、Unity摄像头纹理、访问基于位置的服务以及其他一些Unity技巧。另外还会讨论未来创建多人版本游戏的时候需要哪些技术。最后将介绍一些调试技术，以备不时之需。
