A Point describes an instance to a single geometry point. They are accessible through the SOP.points member.
P → (Read Only):
The coordinates as AttributeData. Individual components can be read or written with the  operator.
point.P = 5
point.P = (1,0,1)
owner → (Read Only):
The OP to which this object belongs.
x → (Read Only):
Get or set x coordinate value. This is the same as P.
y → (Read Only):
Get or set y coordinate value. This is the same as P.
z → (Read Only):
Get or set z coordinate value. This is the same as P.
index → (Read Only):
The point index in the list.
Destroy and remove the actual point this object refers to. This operation is only valid when the primitive belongs to a scriptSOP.
Note: after this call, other existing Point objects in this SOP may no longer be valid.
Each SOP has a list of Points. Each point has an XYZ 3D position value plus other optional attributes. Each polygon Primitive is defined by a vertex list, which is list of point numbers.
