In general the GeoCleaner is a tool to eval and fix a polymesh - very handy for game-modeling. For those who are new to the GeoCleaner visit my site for more information.
For example the vertex color feedback provides you now information about the bending of a surface - furthermore there is a set of repair tools to fix certain issues on already evaluated meshes.
See below an example of an evaluated polymesh showing the curvature as red color.
This turned out to be a very handy workflow for me to check and repair my meshes using this toolset. Simply visit my site to learn more about the updated "geoCleaner".
Just check it out and contact me for any feedback.
