Well I projected the coords onto a graph orthographically, so I had 3 triangles one each as seen from PLAN, SIDE and FACE projection.
I found the midpoint of each, which gave me 2 coords each. either XY,YZ or XZ
Basically, I obtained a value for X Y and Z anyhow
and fed them into my program above, but althogh I am confident abot it being the centre of mass, it is again, not equidistant :(
Thanks for that link, Sswift - very good stuff, only I don't have the angles to work with...
