Vectors are an abstract non-geometrical data type that describe direction and magnitude in space.

Similar to Points, Vectors are composed of three parts. For Vectors these parts are distances, not coordinates, and are described as: {deltaX, deltaY, deltaZ}. Vectors exist anywhere in space because they are abstract and are not tied to a location until they have been anchored. Once anchored to a Point, Vectors can be visualized (typically done with arrows). Using a Summation operation with the Anchor Point and Vector, we can find the Vector’s Terminal Point or tip.

This Vector Primer constructs a vector by component delta values allowing user interaction as well as generating live visual feedback.
