What is the algorithm behind Blender's Proportional Edit?

by Anu Sky   Last Updated January 14, 2018 02:15 AM

How does Blender compute the vertex displacements during Proportional Editing?

I'm guessing it first searches for vertices within the user defined radius, then calculate somehow the weights for each of those found vertices based on degree of connectivity to the seed vertex or distance? Or does it use free form deformation approach?

A paper or reference would be helpful too.
