【摘要】 该文就在复杂的由VRML构造的虚拟实体造型表面进行跨区域纹理映射所遇到的困难 ,提出了一种比较简单有效的跨区域纹理映射的方法。它把原始纹理图像进行一系列的处理之后生成若干图像块 ,并分别将这些图像块映射到不同的造型面上 ,最终实现跨区域的纹理映射。这样的处理过程允许动态地变换纹理图像。另外 ,根据实际的需要还增加了部分附加处理功能更多还原

【Abstract】 Some difficulties are accounted in the course of implementing multi-region texture mapping to the faces of the virtual entity shapes constructed by VRML. In order to resolve the problem, a simpler and efficient method is brought forward to satisfy the requirement. It takes advantage of a series of operation to proceed a complete texture image, and finally creates some independent texture image sections. After that, it respectively maps these texture image sections to different faces of the shapes. Finally, multi-region texture mapping is accomplished. The method permits us to dynamically change the texture image. On the other hand, some additional functions are implemented according to the need.更多还原
