Hi,

I am trying to create an application which the user can use to graphically draw clothoid (Euler spiral) segments, i.e. the user should be able to shape the curve only by using the mouse.

But I am at loss at to which drawing method I should use. I thought of drawing them as Bezier curves but the data is not compatible. How can I paint in Qt curves with specific data, such as curvatures and arc length?

Thanks in advance.
