TYPE: SOP
TITLE: Lattice SOP

Lattice creates animated deformations of its Data Source by manipulating 
simpler geometry that encloses the Data Source's geometry.

In lattice mode, both the initial source and deformed source must
be lattices with the point orders in a specified order.  This is the
order generated by the Box operation when use divisions is turned on.
The number of divisions must match that of the geometry or an error is
returned.

In point mode, both initial source and deformed source must have the
same point counts.  Note that any points not within the specified
radius of a point in the initial source will not be deformed.  The
amount of deformation applied to a point is based upon the weighted
average of the deltas of the initial source to the deformed source.
The weighting function is taken from the specified metaball kernel,
so behaviour is similar to applying a magnet metaball to every point
in the initial source.

Inputs:
    Data Source     - The geometry you wish to deform. 
    Initial Source  - The rest geometry used to determine the influence
		      of points in the deformed geometry.
    Deformed Source - A deformed version of the rest geometry.  The
		      difference between this and the rest geometry is
		      used to calculate the deformation to apply to the
		      data source.
Parameters:
    
    Group      - Points in the first input to be deformed.

Lattice
    Overview   - Deform with a regularly space lattice
    Divisions  - Must match the number of divisions in     /divsx /divsy /divsz
                 the lattice grid.

Points
    Overview   - Deform using arbitrary point clouds
    Rest Group - Points in the rest geometry which are used.  The
                 corresponding points in the deformed geometry are
                 used as the implicit deform group.
    Kernel     - Which meta kernel to use to determine the influence of
                 a point.
    Radius     - The size of the points capture regions.                /radius
