Hi
This is a question for pythagoras rather than PlayN.
I'm using pythagoras.f.GeometryUtil to calculate intersections between lines, quad curves and cubic curves.
Lines and quads works as expected, but cubic curves I cannot make it work right (neither with lines, quads or cubics)
For example this code
GeometryUtil.intersectLineAndCubic(350, 670, 500, 100, 300, 300, 380, 520, 340, 430, 600, 560, new float[6]);
which is for this line and cubic curve
returns 0 roots, when there's clearly an intersection.
