RT info:eu-repo/semantics/article T1 Finite piecewise polynomial parametrization of plane algebraic curves A1 Pérez Díaz, Sonia A1 Sendra Pons, Juan Rafael A1 Villarino Cabellos, Carlos K1 Piecewise polynomial parametrization K1 Rational algebraic curves K1 Error analysis K1 Matemáticas K1 Mathematics AB We present an algorithm with the following characteristics: given a real non-polynomial rational parametrization P(t) of a plane curve and a tolerance ϵ>0 , R is decomposed as union of finitely many intervals, and for each interval I of the partition, with the exception of some isolating intervals, the algorithm generates a polynomial parametrization PI(t) . Moreover, as an option, one may also input a natural number N and then the algorithm returns polynomial parametrizations with degrees smaller or equal to N. In addition, we present an error analysis where we prove that the curve piece CI={P(t)|t∈I} is in the offset region of C∗I={PI(t)|t∈I} at distance at most 2–√ϵ , and conversely.
