Hi Michael,
by the way i looked deeper in the method extractPoint of the
LengthIndexLine and at the bottom I found the method
public static Coordinate pointAlongSegmentByFraction(Coordinate p0,
Coordinate p1, double frac)
{
if (frac <= 0.0) return p0;
if (frac >= 1.0) return p1;
double x = (p1.x - p0.x) * frac + p0.x;
double y = (p1.y - p0.y) * frac + p0.y;
return new Coordinate(x, y);
}
That actually computes the result and this is pretty the same calculation
I wanted to use ;-) ("Vector" geometry)
Cheers,
Martin
