示例1: unitVector
Geom::Piecewise<Geom::D2<Geom::SBasis> >
LPEOffset::doEffect_pwd2 (Geom::Piecewise<Geom::D2<Geom::SBasis> > const & pwd2_in)
{
using namespace Geom;
Piecewise<D2<SBasis> > output;
double t = nearest_point(offset_pt, pwd2_in);
Point A = pwd2_in.valueAt(t);
double offset = L2(A - offset_pt);
Piecewise<D2<SBasis> > der = unitVector(derivative(pwd2_in));
Piecewise<D2<SBasis> > n = rot90(der);
output = pwd2_in + n * offset;
append_half_circle(output, pwd2_in.lastValue(), n.lastValue() * offset);
output.continuousConcat(reverse(pwd2_in - n * offset));
append_half_circle(output, pwd2_in.firstValue(), -n.firstValue() * offset);
// TODO: here we should remove self-overlaps by applying the "union" boolop
// but we'd need to convert the path to a Shape, which is currently
// broken in 2geom, so we return the unaltered path
return output;
