The "informative paper" you are looking for likely refers to the foundational research that introduced this technology: by Olivier Dionne and Martin de Lasa. This SIGGRAPH 2013 paper details the algorithm used to calculate skinning weights based on geodesic distance within a voxelized version of a character's mesh. Key Features of Voxel Heat Diffuse Skinning: Maya 2015 Geodesic Voxel Bind

The request for refers to a specific version of the Voxel Heat Diffuse Skinning add-on, a popular tool used to automate and improve character skinning in 3D software. Understanding the Tool and "Informative Paper"

and actually I'm going to go in and just hide the environment. so we can get a kind of close look at what the skinning looks like. YouTube·My Oh Maya
