How do I get the distance between two points, in global space?
I have tried to subtract two vectors, and then use GetLenth(), but I get different results depending on the order of the two vectors, and have a feeling I do not do it right.Yes, it is a basic question I assume, but I have not needed this before now.
To clairify, in this case I want to know how this is done for two null objects, just to make it as simple as possible.

Hi ingvar,
your approach doesn't sound very wrong.
Matrix mg1 = op1>GetMg(); Matrix mg2 = op2>GetMg(); Vector p1 = op>GetPointR()[42]; Vector p2 = op>GetPointR()[31]; Float distance = ((mg2 * p2)  (mg1 * p1)).GetLength();
what did you do differently?
Best,
Niklas

And you are so right, I have done it correctly. But i used some numbers from another part of my code, where I did it wrong!! So I though my latest calculation also was wrong.
Still I learnt something from you post, I have done it the simple way, like this:Matrix mgA = opA>GetMg(); Matrix mgB = opB>GetMg(); Real distance = (mgA.off  mgB.off).GetLength();
And this works, for Nulls, as well as PolygonObjects.
Now also can calculate the distance between points too, thanks!
