[vtkusers] How to find the distance from a point in a triangle to all three faces of the triangles.?

[rakesh patil]

Hello,

I tried to google the solution for this problem. But I guess there is no
direct way to do this. The problem is as explained below:

There exists a trianglular mesh. Once I click on one of the element of the
mesh, it is to be checked whether user has clicked inside the triangle or on
the edges of triangle. If user has clicked inside the triangle, then, I need
to find the 3 distances, i.e. distance from the clicked point to the 3 edges
of the triangle (or 3 faces of the triangle). Is there a direct way to
achieve this task?

One way what I found was using this logic here

Any other easy way will be appreciated.

Thanks in advance.
