摘要
Direct X是 Microsoft公司开发的运行于计算机平台的多媒体控制处理引擎。在 Direct X中 ,要实现三维旋转 ,需要通过世界转换、视图转换和投影转换 ,三种转换则要通过矩阵相乘来实现。论述了三维旋转的机理 。
Direct X developed by Micrososft company is the engine to control and process multimedia in computer platform.3D rotation in Direct X can be implemented by transformation of world,view and projection,and three transformations can be realized by matrix multiplication.The paper discusses the principle of 3D rotation,and gives a simple practical example.
