Hi Guys, I've been watching this site for a while now but this is my first topic.
Basically I have a triangular 3Dface aligned in an arbitary 3D plane, corners defined as:
(X1,Y1,Z1) (X2,Y2,Z2) & (X3,Y3,Z3)
I would like to know what formula I should be using to obtain a Z elevation for a given point (X,Y) picked somewhere within the triangle.
Any suggestions would be most welcome.
Didge.
