This is a three-component point in space (as opposed to a three-component vector, which represents a direction and a distance).
Some of the methods are slightly different between LPoint3 and LVector3; in particular, subtraction of two points yields a vector, while addition of a vector and a point yields a point.

| static Point3D origin | ( | ) | [static] |
Returns the origin of the indicated coordinate system.
This is always 0, 0, 0 with all of our existing coordinate systems; it's hard to imagine it ever being different.

Returns the origin of the indicated coordinate system.
This is always 0, 0, 0 with all of our existing coordinate systems; it's hard to imagine it ever being different.
Returns a new vector representing the projection of this vector onto another one.
The resulting vector will be a scalar multiple of onto.
