Re: Will be the Cage based transform included in the next Gimp release?

[Michael Muré <batolettre@xxxxxxxxx>]

Hello,

The cage tool is based on the Green coordinates (http://www.math.tau.ac.il/~lipmanya/GC/gc.htm). These coordinates are not defined outside the cage, so the cage tool wont be able to affect point outside the cage. There is a mathematical possibility to expand the cage trough one edge of the cage, but i think that the way it would work isn't relevant for the gimp use case.

However, the cage tool already implement almost half of a future iwarp tool. Most of the deformation backend can be reused as is, and the deformation logic of the cage tool can be adapted to code an iwarp tool. 

Best regards,
