TYPE: SOP
TITLE: UVTransform SOP

The UV ransform operation transforms UV texture coordinates on the
source geometry.  Unlike the UVEdit operation, UVTransform supports
animation of UVs.

UVTransform will automatically detect whether the input geometry uses point or
vertex UV attributes, and will affect these attributes appropriately.

3D transforms are allowed in the UVTransform operation, as the UV attribute is
actually 3 coordinates: U, V, and W.

When used interactively, translates and scales are along the U/V axes while
rotations are about the W axis.

Parameters:

    Group           - Subset of geometry to apply current operation to.
    Group Type      - The type of elements referenced in the Group field.
    
    Transform Order - Order in which transformations occur.
    Rotate Order    - Order in which rotations occur.
    Translate       - Amount of translation along uvw axes.          /tx /ty /tz
    Rotate          - Amount of rotation about uvw axes.             /rx /ry /rz
    Scale           - Non-uniform scaling along uvw axes.            /sx /sy /sz
    Pivot           - Local pivot point for transformations.         /px /py /pz
    Pivot about Group Centroid - Set the pivot to the center of the input group.
    
    Soft Radius     - Area of influence.                             /rad
    Soft Type       - Type of rolloff function.
    Tangent Angles  - Angles of the cubic rolloff function's tangents.
                      The first value applies to the tangent farthest from the
                      source point, the second applies to the tangent closest
                      to the source point.                           /tandeg
    Kernel Function - Metaball kernel to use when rolloff Type is "Meta-ball"
    Metric          - Measure of distance to use when performing a soft
                      transform.
	XYZ - Corresponds to distance on the geometry.
	UVW - Corresponds to distance in UVW (texture) space.
	UV  - Ignores the third dimension in texture space.
    Ignore Point Connectivity - Affect only points connected to the points in
                                the group, or all points within the radius.
    Ignore UV Connectivity - Affect only vertices connected to the vertices
                             in the group as seen in the UV viewport.
