掌握UVW贴图映射视频教程Lynda Mastering UVW Mapping in Houdini 16.5 含英文字幕
学习如何运用Houdini 16.5的UVW mapping的应用和细化纹理。在这门课程中，作者Joel Bradley介绍了Houdini 16.5中可用的UV工具，并分享了它们可能有用的具体情况。Joel首先解释了UV映射的功能，为什么你需要它来构建你的网格，以及如何设置、测试和修改UV。然后他转向更高级的主题，如UV投影、纹理和毛皮贴图。他还展示了如何为复杂的对象映射分类选择和创建接缝，以及如何缝合特定的UV簇，以更好地管理接缝。最后，Joel提供了一个强大的游戏开发工具集，在使用Houdini及其UV映射工具包时，您可以使用它来做更多的游戏。
UVW其实对应的就是空间坐标的XYZ，或者说和XYZ的概念相同。一般来说，UVW用来代表贴图坐标系，XYZ代表空间坐标系，其实概念相同。一张平面贴图，U代表横向，V代表纵向，W代表垂直屏幕的方向。这和3D空间的XYZ坐标是一样的，在3D空间中，X代表横向，V代表纵向，W代表垂直屏幕的方向。UVWmap是指贴图在模型上贴图的方向，U、V、W分别指X、Y、Z三个轴向上的贴图，你可以调整这三个轴向上的参数改变贴图的大小。
Learn how to apply and refine textures on 3D objects in Houdini with UVW mapping. In this course, Joel Bradley walks you through the UV tools available in Houdini 16.5 and shares specific situations where they may prove useful. Joel begins by explaining what UV mapping does, why you need it for your meshes, and how to set up, test, and alter UVs. He then moves on to more advanced topics, such as UV projection, texturing, and pelt mapping. He also shows how to group selections and create seams for complex object mapping, and how to sew specific UV clusters together for better seam management. Finally, Joel provides a look into the powerful Game Development Toolset that you can use for much more than games when working with Houdini and its UV mapping tool kit.
