Before asking, I would like to clarify some terms and please help me if I’m wrong because English is not my native language. English has vey confusing usage of “Direction”, because it is used for two different things.
Direction is an infinite line defined by two points (A and B). Course (or some other word I don’t know of) is an infinite line that has information about the movement as well (A towards B or B towards A). Correct me if I’m wrong.
I understand that vectors in Dynamo can be directions. How can I create the course?
Imagine you have landed on a deserted island, and you have a map showing you where some long lost treasure is and a compass. You know it’s 15 paces east, then 20 paces north, and 3 paces west. In order to make sure you can get back safely you tie a rope to a pin at the starting point and lay down a little more rope each step you take.
To me: Direction is the compass heading: north, east, south, west. Course is the resulting rope layout.
To me directions are best expressed as vectors, and courses as a type of curve (nurbs, polycurve, etc.).
Ok, now that I understand what is a direction, can you please explain how is that direction expressed in a vector? I see X, Y, Z, and length as output… I don’t get it.
Aaah, I get it now. The vector is just showing the X,Y,Z of the point towards the object is hypothetically moving, just as you would be moving from Africa toward the North Pole, the vector in Dynamo would be showing the coordinates of the North Pole, Am I right?
