If the texCoord field is NULL, a default texture coordinate mapping is calculated using the local

coordinate system bounding box of the shape. The longest dimension of the bounding box defines the S coordinates,
|

and the next longest defines the T coordinates. If two or all three dimensions of the bounding box are equal,

ties shall be broken by choosing the X, Y, or Z dimension in that order of preference.

The value of the S coordinate ranges from 0 to 1, from one end of the bounding box to the other.

The T coordinate ranges between 0 and the ratio of the second greatest dimension of the bounding box to the greatest dimension.
