That's great Ahmidou, looking forward to it.

Thanks Ben. That is some good info. I was thinking more along implementing the
Harmonic Coordinates approach. I think Pixar had some papers on it.

The scan conversion bit with the laplacian solver seems like a lot of work.
There is the idea of mean value coordinate systems which may allow for a
smooth interpolant across the arbitrary
Turns out mean value coordinates on closed polygon meshes to do deformation

I already implemented this paper in ICE:

The result is pretty closed to harmonic coordinates,
Hi All,
Very soon, I am starting on my own generic custom cage deformer. A mix of
C++/Cython/Python.
I am thinking of implementing fast calculations on barycentric coordinates
with affine transformations. I have some good papers (in my treasure trove
but haven't checked it yet).
Anyone suggest
My knowledge is out of date, but off the top of my head
Cage deformers are often written using a cubic interpolant rather than
affine ones. If you use a grid cage you can use Bezier Volumes, which are
just a generalization of https://en.wikipedia.org/wiki/B%C3%A9zier_surface.
