摘要:为了增强在虚拟空间进行漫游的真实感,对其实现的核心技术视点控制进行了研究。分析了利用开发工具提供的函数来完成视点控制的优缺点。结合实际开发经验,给出了一种利用三角函数实现视点控制的算法。利用数学三角函数实现视点控制算法,能够使视点控制更符合人的真实视点,为后期真实感绘制的编程降低了难度,增加了灵活性,并且该算法可以很好的移植到其它虚拟现实相关软件的开发中。
In order to enhance the virtual reality of roaming space, the realization of its core technology to control viewpoint is studied. The advantages and disadvantages of viewpoint control is analyzed with function using the development kit. The actual development experience is unified, one kind is given to realize the viewpoint control algorithm using the trigonometric function. The viewpoint control algorithm is realized using mathematics trigonometric function, it can cause the viewpoint control to conform to person' s real viewpoint, reduced the difficulty for the later period third dimension plan' s programming, increased the flexibility, and this algorithm is the very good transplant to other virtual reality related software' s development.
