We present an algorithm to decide whether a given parametrization of a rational swung surface, with coefficients in K(i), can be reparametrized over a real (i.e., embedded in R) finite field extension of K. Swung surfaces include, in particular, surfaces of revolution. %K Swung surfaces %K Revolution surface %K Real and complex surfaces %K 8 rational parametrization %K Ultraquadrics %K Ciencia %K Matemáticas %K Science %K Mathematics %~ Biblioteca Universidad de Alcala
