Description

This tool is described in code as “Rubber-like deformation of image using points”.

Implementation

This algorithm was implemented by the paper’s author themselves, as a Google Summer of Code project in 2013.

Unfortunately, though the effect is very interesting, the tool is also much too slow and crash-happy, which is why it is still hidden in the Playground area.

We welcome contributions to make the tool fast and stable.
