I'm trying to script the modeling of a set of 3D vectors. For a given vector, I have the start and end points in 3D space -- for example from 1,1,1 to 2,2,2. I'm not sure of the best way to approach this problem.
I'm imagining a cylinder with a cone on the end ("arrow") all grouped together that is located in some arbitrary location but with a unit length (e.g., 0,0,0 to 0,0,1). My inclination was parent the arrow to a bone and the translate the bone to the first position, followed by translation of the other end of the bone to the second position. Since the arrow is radially symmetric, rotation won't be an issue.
This solution seemed convoluted to me though (building an armature, etc.), since I have the endpoints where the geometry should go. It seems like there should be a way to translate the central node of the cylinder to point 1 and then translate/rotate the node at the tip of the cone to point 2.
