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, 0.0).

Remember to add a third item (0.0, 0.0, 0.0) for usage in the vector Routines such as VS:Vec2Ang or they will return gibberish.

[MaKro 11/2021] Did not dig deeper, but looks like beg and end can be interpreted as: vs.RelativeCoords(p, p_origin, x_axis)

Example

VectorScript

PROCEDURE Example;
VAR
    pt, beg_pt, end_pt, v :VECTOR;

BEGIN
    Message('Set begin point');
    CallTool(-221); { creates a locus }
    GetLocPt(FSActLayer, beg_pt.x, beg_pt.y);

    Message('Set end point');
    CallTool(-221); { creates a locus }
    GetLocPt(FSActLayer, end_pt.x, end_pt.y);

    Message('Set point');
    CallTool(-221); { creates a locus }
    GetLocPt(FSActLayer, pt.x, pt.y);

    v := RelativeCoords(pt, beg_pt, end_pt);
    Message('result vector=', v);
    Locus(v.x, v.y);
END;
RUN(Example);
