offsetCurve method
Returns a List of Bezier
instances that, when taken together, form an approximation
of the offset curve distance
units away from this.
See simpleSubcurves for information about the optional parameter stepSize
.
Implementation
List<Bezier> offsetCurve(double distance, {double stepSize = 0.01}) {
if (isLinear) {
return [_translatedLinearCurve(distance)];
}
final reducedSegments = simpleSubcurves(stepSize: stepSize);
final offsetSegments = reducedSegments.map((s) => s.scaledCurve(distance));
return offsetSegments.toList();
}
