Characterizes mappings preserving Pythagorean-hodograph curves.
This paper constructs PH spline curves with prescribed arc lengths.
The present paper attempts to show an alternative approach with regards to rational Pythagorean-hodograph (PH) curves and especially more natural approach for rational PH helices (i.e. rational helices). It exploits geometric features of rational helices to obtain a simpler construction of these curves and apply this t…
