Textures and UVs纹理和UV
Textures are pixel maps, usually image files, you use to control surface values such as color, opacity, displacement, and so on.
–纹理是一个像素贴图，通常是图像文件，你可以使用它控制曲面的一些数值，如颜色，不透明度，置换等。
To map textures to surfaces, Houdini must know which parts of the pixel map should appear on which parts of the surface. You do this by puttingUV coordinates attributes on the surface, which map to pixels in the texture. In Houdini, you need to add UVs to all surface types. NURBS surfaces do not automatically have UV coordinates.
–要映射纹理到曲面上，Houdini必须要指定像素贴图中哪个部分会出现在曲面的哪个部位上。在Houdini中，你需要给所有曲面添加UV。NURBS曲面不会自动产生UV坐标。
See the Texture tab shelf help to learn about adding and editing UVs.
–查看纹理选项卡的帮助学习关于添加和编辑UV的部分。
You can quickly put a texture on a surface with the UV Quick Shade SOP.
–使用UV Quick Shade 节点你可以快速放置一个纹理到曲面上。
You can use textures in your custom shaders with the Texture VOP.
–你可以用Texture VOP节点在你自定义的材质上使用纹理贴图。
