基于UVW贴图和UVW展开的贴图技法探究

Research on Mapping Techniques based on UVW Mapping and UVW Expansion

通常,将简单或程序材质应用于对象并不难,但是,当表面需要在其上显示某种纹理时,它会变得更加复杂。恰好UVW贴图和UVW展开修改器都是用于将贴图(纹理)坐标指定给对象和子对象,并手动或通过各种工具来编辑这些坐标,还可以使用它们来展开和编辑对象上已有的UVW坐标。此时,可使用多种程序方法的任意组合来调整贴图,使其适合网格、面片、多边形、HSDS和NURBS模型,适用于模型本身较为复杂、渲染结果无法预知的情况。

In general,it is not difficult to apply simple or procedural materials to objects.However,when a surface needs to display a texture,it becomes more complex,as both the UVW map and the UVW expansion modifier are used to assign map(texture)coordinates to objects and child objects,and manually or through a variety of tools to edit these coordinates,you can also use it to expand and edit the objeet's existing UVW coordinates,at this point using a variety of program methods to adjust any combination of maps,it is suitable for mesh,polygon,HSDS and NURBS models,and is suitable for cases where the model itself is complex and the rendering result can not be predicted.
