How to calculate the distance between a Vector3 and a (3D polygon triangle)?
for example : " float DistanceToTrianale( Vector3 pos, Vector3 Edges1, Vector3 Edges2, Vector3 Edges3)
thanks in advance

\$\begingroup\$ I say this not having easy access to it where I'm at right now, but have a copy of realtimecollisiondetection.net/books/rtcd on hand or you're doing life wrong. The answer boils down to using Voronoi regions and easy math, all explained in detail in that book. \$\endgroup\$– Sean MiddleditchCommented Mar 29, 2013 at 21:17

Here is a nice guide to the problem, with implementation:
