i had to study barycentric coordinates
The collision detection uses the Moller-Trumbore algorithm
... and the new version of mcjCollider ( for DS3 and DS4.5 ) will report the UV coordinate of the hit point
so this fall or winter i’ll probably write a script or a plugin to do 3D painting!
in the image below, i painted a cross in Paintshop, at the UV coordinate reported by mcjCollider
and it fits !
