Convert Mouse Points to Quadratic BSplines

Question

Hi All,

I'm writing a drawing program. I'm trying to take an ordered list mouse positions, and approximate a smooth Quadratic BSpline Curve. Does anyone know how to accomplish this?

Thanks!

Answer 1

"B-spline curve fitting based on adaptive curve refinement using dominant points" by Park & Lee and "Fair interpolation and approximation of B-splines by energy minimization and points insertion" by Vassilev seem to be solving this problem. Also there look like a few references on the first link that should help you.

Converting data points to control points in areas of high curvature and removing data points in areas of little curvature is a general approach.
