View Full Version : How to write "d = norm(cross(BA,PA))/norm(BA)" in maya expression?
deluxmilkman 03292012, 03:41 PM d = norm(cross(BA,PA))/norm(BA);
This is a formula for finding the distance between a point and a line segment in 3D space.
A, B, and P are all vectors.
Maya expression is not taking "norm" procedure.

there is no procedure "norm". I think you want "unit"

I suggest the usage of mag() because I suppose you need the length of the vectors.

yeah, the fornula was wrong.
it was mag.
d = (P  A) x (P  B) / (B  A)
where ".." denotes the magnitude value (positive) and "x" is the cross product.
thanks.
