|
|
|
__div__
|
__div__ ( self, scalar )
Return v/r.
|
|
|
__eq__
|
__eq__ ( self, other )
Return u == v.
|
|
|
__ge__
|
__ge__ ( self, other )
|
|
|
__getitem__
|
__getitem__ ( self, index )
|
|
|
__gt__
|
__gt__ ( self, other )
|
|
|
__init__
|
__init__ (
self,
x,
y,
z,
)
|
|
|
__le__
|
__le__ ( self, other )
|
|
|
__len__
|
__len__ ( self )
|
|
|
__lt__
|
__lt__ ( self, other )
|
|
|
__mul__
|
__mul__ ( self, scalar )
Return v r.
|
|
|
__ne__
|
__ne__ ( self, other )
Return u != v.
|
|
|
__neg__
|
__neg__ ( self )
Return -v.
|
|
|
__rmul__
|
__rmul__ ( self, scalar )
Return r v.
|
|
|
__str__
|
__str__ ( self )
|
|
|
__sub__
|
__sub__ ( self, other )
Return u - v.
|
|
|
bound
|
bound ( self, norm )
Return a vector in the same direction, but whose length is no
greater than norm.
|
|
|
cross
|
cross ( self, other )
Return the cross product, u cross v.
|
|
|
dot
|
dot ( self, other )
Return the dot product, u dot v.
|
|
|
isUnit
|
isUnit ( self )
Does this vector has unit norm?
|
|
|
norm
|
norm ( self )
Return the vector norm.
|
|
|
normSquared
|
normSquared ( self )
Return the squared vector norm. If it is not necessary to
actually calculate the norm, this is more efficient since it
does not involve a square root.
|
|
|
unit
|
unit ( self )
Return a vector in the same direction but whose length is
unity.
