I can XOR a vector

pxvec = pxvec ^ vecmask

how do I XOR a single axis

pxvec.x = pxvec.x  ????  vecmask.x

pxvec.x = pcvec.x * vecmask.x

Vector XOR just multiplies componentwise.

thanks

I couldn't make sense of the SDK syntax '__rxor__(self,other)'

or the example

I thought % was a modulo operator?

Vector.\__rxor\_\_(self, other)[](file:///Users/paultaylor/Documents/Media/3D/Programming/Python/CINEMA4DR15037PYTHONSDKHTML20130823.zip%20Folder/help/modules/c4d/Vector/index.html?highlight=xor#Vector.__rxor__)

Multiplies two vectors together componentwise and set the left hand vector to the result:

import c4d
v_result = c4d.Vector(1,2,3)%c4d.Vector(2,3,4)
#v_result => Vector(2,6,12)

_<_t_<__<_t_>_<_<_t_>_lgroup>Param :	The other argument.
Return type:	[Vector](file:///Users/paultaylor/Documents/Media/3D/Programming/Python/CINEMA4DR15037PYTHONSDKHTML20130823.zip%20Folder/help/modules/c4d/Vector/index.html?highlight=xor#c4d.Vector)

Well, that's a typo in the docs. The modulo operator performs the cross product.
Thanks for the notice.

So how do you form this with the example above pls?

can't figure the syntax

__rxor__(self,other)

xvec.x = pcvec.x__rxor__(vecmask.x)

I don't get what you are trying to do. Vector.__rxor__() is only called in some special cases, see

https://docs.python.org/2/reference/datamodel.html#object.__rxor__

If you want to multiply two vectors componentwise, use the ^ operator. The * operator on Vectors
performs the dot-product. If you want to multiply one component of a vector with another, use
the * operator. You can't multiply a  vector component componentwise as there is only one component
which is the value itself.
