Hi,

Is there a way to find out the points on a clothoid, i.e. their coordinates, if one knows the start point and the end point of the clothoid and its curvature?

You can do that for any planar curve with known curvature, .

Let the curve be , parametrized for arclength.

Then , which implies there exists a function such that

.

From the formula for curvature, ,

and so the curve is .

Now use to determine the constants.
