Description
Translates a point into a coordinate system defined by 2 other points.
FUNCTION RelativeCoords(
pt :VECTOR;
begPt :VECTOR;
endPt :VECTOR) : VECTOR;
def vs.RelativeCoords(pt, begPt, endPt): return VECTOR
Parameters
pt VECTOR begPt VECTOR endPt VECTOR
Remarks
(_c_, 2022.01.19) In Python the tuple returned is always bidimensional in the form (0, 0).
Remember to add a third item (0, 0, 0) for usage in the Vector Routines such as VS:Vec2Ang or they will return gibberish.
