Hi ristjan,
sorry for not getting back to you earlier! Thanks for your
help, I've managed to get the information I was looking for. Turns out
vertex normal did gave me what I was looking for but since I did not build
an up vector for the matrix the locator did not know how to orient it self.
Using connectedVertices to build the up vector was what I ended up doing.
Thanks again!
Thank you
Gann Boon Bay
