OverlapLineArc

Description

Finds the overlap of a line and an arc. Returns the overlapping segment if it exists.

FUNCTION OverlapLineArc(
				begPt      : VECTOR;
				endpt      : VECTOR;
				cenPt      : VECTOR;
				radius     : REAL;
				startAng   : REAL;
				sweepAng   : REAL;
				VAR lapPt1 : VECTOR;
				VAR lapPt2 : VECTOR;
				tolerance  : REAL): BOOLEAN;
def vs.OverlapLineArc(begPt, endpt, cenPt, radius, startAng, sweepAng, tolerance):
    return (BOOLEAN, lapPt1, lapPt2)

Parameters

Name Type Description
begPt VECTOR
endpt VECTOR
cenPt VECTOR
radius REAL
startAng REAL
sweepAng REAL
lapPt1 VECTOR
lapPt2 VECTOR
tolerance REAL

Examples

resultOK := OverlapLineArc(begPt, endpt, cenPt, 1.0, 2.0, 0.5, lapPt1, lapPt2, 1.5);
import vs

# Finds the overlap of a line and an arc.
begPt = (0, 0)
endpt = (2, 2)
cenPt = (2, 0)
radius = 1.0
startAng = 1.0
sweepAng = 2.0
tolerance = 0.5

ok, lapPt1, lapPt2 = vs.OverlapLineArc(begPt, endpt, cenPt, radius, startAng, sweepAng, tolerance)
vs.Message('OverlapLineArc returned: ' + str((ok, lapPt1, lapPt2)))
