Concatenates the transformations ti and sets the result as the current transformation matrix for 3D texture coordinates. 3D texture coordinates can be created by any geometric primitive (simply by taking their world or object coordinates).
Transformations for texture coordinates don't accumulate when the scene graph is traverted, this means this matrix overwrites any previously set matrix.
The TEX3TRANSFORMS group is a attribute, this means it is only allowed to be present in a ATTRIBS (6.2.1), LOCAL_ATTR (6.2.2) or OVWRT_ATTR (6.2.3) attribute group, and the same override rules as for other attribute nodes apply to it.
The ti must be transformation type nodes.
