=== Invert Vector ===
This script inverts the given vector.

<source lang = "python">
from Blender import Node

class InvertVectorNode(Node.Scripted):
def __init__(self, sockets):
sockets.input = [Node.Socket('Vector', val = 3*[1.0])]
sockets.output = [Node.Socket('Vector', val = 3*[1.0])]

def __call__(self):
self.output.Vector = map(lambda x: -x, self.input.Vector)

__node__ = InvertVectorNode
</source>

=== Merge Vector ===
Merges 3 values into a vector.

<source lang = "python">
from Blender import Node

class MergeVector(Node.Scripted):
def __init__(self, sockets):
vec = Node.Socket('Vector', val = [1.0, 1.0, 1.0])
valx = Node.Socket('X', val=1.0, min=-10e6, max=10e6)
valy = Node.Socket('Y', val=1.0, min=-10e6, max=10e6)
valz = Node.Socket('Z', val=1.0, min=-10e6, max=10e6)

sockets.output = [vec]
sockets.input = [valx, valy, valz]

def __call__(self):
ovec = [0.0, 0.0, 0.0]

ovec[0] = self.input.X
ovec[1] = self.input.Y
ovec[2] = self.input.Z

self.output.Vector = ovec

__node__ = MergeVector
</source>

=== Quantizes Vector ===
Quantizes a vector by a value.

<source lang = "python">
from Blender import Node

class QuantizeVector(Node.Scripted):
def __init__(self, sockets):
vec = Node.Socket('Vector', val = [1.0, 1.0, 1.0])
val = Node.Socket('Quantize', val=1.0, min=0.001, max=100.0)
sockets.input = [vec, val]
sockets.output = [vec]

def __call__(self):
ovec = list(self.input.Vector)
oqval = self.input.Quantize
ovec[0] = ((ovec[0]/oqval)-(ovec[0]%oqval))*oqval
ovec[1] = ((ovec[1]/oqval)-(ovec[1]%oqval))*oqval
ovec[2] = ((ovec[2]/oqval)-(ovec[2]%oqval))*oqval
self.output.Vector = ovec

__node__ = QuantizeVector
</source>

=== Scale Vector ===
Multiplies a vector by a value.

<source lang = "python">
from Blender import Node

class ScaleVector(Node.Scripted):
def __init__(self, sockets):
vec = Node.Socket('Vector', val = [1.0, 1.0, 1.0])
val = Node.Socket('Value', val=1.0, min=-10e6, max=10e6)
sockets.input = [vec, val]
sockets.output = [vec]

def __call__(self):
ovec = list(self.input.Vector)
oval = self.input.Value
ovec[0] *= oval
ovec[1] *= oval
ovec[2] *= oval
self.output.Vector = ovec

__node__ = ScaleVector
</source>

=== Split Vector ===
Splits a vector into 3 values

<source lang = "python">
from Blender import Node

class SplitVector(Node.Scripted):
def __init__(self, sockets):
vec = Node.Socket('Vector', val = [1.0, 1.0, 1.0])
valx = Node.Socket('X', val=1.0, min=-10e6, max=10e6)
valy = Node.Socket('Y', val=1.0, min=-10e6, max=10e6)
valz = Node.Socket('Z', val=1.0, min=-10e6, max=10e6)
sockets.input = [vec]
sockets.output = [valx, valy, valz]

def __call__(self):
ovec = list(self.input.Vector)
self.output.X = ovec[0]
self.output.Y = ovec[1]
self.output.Z = ovec[2]

__node__ = SplitVector
</source>

=== Vector to RGB ===
This script converts given vector to RGB.

<source lang = "python">
from Blender import Node

class VectorToRGBNode(Node.Scripted):
def __init__(self, sockets):
sockets.input = [Node.Socket('Vector', val = 3*[1.0])]
sockets.output = [Node.Socket('Color', val = 4*[1.0])]

def __call__(self):
self.output.Color = list(self.input.Vector) + [1.0]

__node__ = VectorToRGBNode
</source>
