bezier splines can introduce tolerance problems

Stefan Pauly's picture

source: phd of Raph Levien

see and

On site 141 he describes tolerance problems of cubic bezier splines.

For improvement of splines he has two ways: improved optimized splines or new spiro splines based on Euler spiral function.

python source code of this splines is also available. He introduces this new better splines for fonts art in Inkscape and work now for Google.

My questions here: Do you know this thesis of Levien?

My experience: model tolerance problems and model exchange problems can have the source in different spline mathematics.

I think here is a potential for optimized bezier splines and new Euler spiral based shiro splines by Levien.
