The Position Operator lets you define a single point in space where particles should be placed. In many cases, this operator is used in concert with the Born Operator to feed in the position where the user wants the particles to be emitted from.

ON - (Bool) This input data
stream determines whether the operator is considered 'on' or 'off'. You
can connect other operators to this input channel such as a Bool
Helper to activate/deactivate the whole operator.
Time - (Time) This input data stream is used to define the local
time for the operator when the user wants to override the default system
time.
Particle - (Particle) This input data stream reads in the currently
selected particle group that is to be used as the source for the positional
adjustment. This data stream MUST be connected and will
be highlighted yellow if it is not.
Position - (Position) This input data stream supplies the current
particle position and overrides the existing X,Y and Z-axis spinners.
No Operator Outputs.
Position - Use the X, Y and Z-axis spinners to set the positional
information for the particles.
Variation - The variation spinner provides an "offset"
value for particle placement. It is important to note that this value
affects all three axes equally, even if one or more of them is set to
0.0. So if you have all of your Position spinners set to 0.0 and have
a Variation value of 10.0 - particles will be placed randomly in a 10x10x10
area surrounding the origin.
Replace - When this option is chosen, the particle's position
is taken from the Position input data stream and the spinners' values
are not used.
Added - If you choose this option, the position data specified
within this operator is added to the existing position for the particles.
So, if you have a Position Born operator generating particles into a group
at XYZ=10,10,0, and you set up a second DynamicSet to input the group's
particles into this Position Operator with XYZ =0,10,0 and Added turned
on, that the position for the particles would then be 10,20.0.
