The Lattice Transform - Utilities is a collection of tools to bend, crop and transform any input image by using a lattice of 12 Points. The input image gets interpolated between the lattice points using Catmull-Rom Splines to get smooth continous UVs.
Some Highlights:
Grayscale and Color Version of the nodes
12 lattice points create a very stable and flexible grid
Adjustable Tension Parameter to get more control over the interpolation
Adjustable Subdivisions to create very smooth transformations
