<textureCoord> ‐Texture coordinates
This element defines the (u,v) texture coordinates of a 2D texture.
The float values of the u and v attributes define the texture coordinates. The index attribute is required when the textureCoord is the child element of tabtextureCoord.
None.
The example below defines the texture coordinates (0.6, 0.8).
<textureCoord index="1" u="0.6" v="0.8" />
