Subtracting 2 vectors in python

[j00ey]

Hi all

Can anyone shed some light on some vector math for me? I'm trying to subtract 1 Vector3 from another and I'm totally stumped.

 Running help(nuke.math.Vector3) gives me this info:

| __sub__(...)
| __sub__( (Vector3)arg1, (Vector3)arg2) -> object :

but I've no idea how to use it.

Any help greatly appreciated!

__sub__ is a special command that just replaces:

object = arg1 - arg2

,where arg 1 and arg 2 are Vector3 types, with:

object = arg1.__sub__(arg2)

which makes sense since the first object is self. Basically it mean if you have 2 vectors then you use normal mathematical notation to do it.

 The docs are somehow auto generated form a strongly typed language such as c++, and just create some text that happened to be there.
