5 sie 2020 · return {x:x, y:y}; } If is just used as getPos(myElem) will return global position. If a second element is included as an argument (i.e. getPos(myElem, someAncestor)) that is an ancestor/parent of the first (at least somewhere up the chain) then it will give the position relative to that ancestor.
The length of the line segment represents the magnitude of the vector, and the arrowhead pointing in a specific direction represents the direction of the vector. The common types of vectors are cartesian vectors, column vectors, row vectors, unit vectors, and position vectors.
