Topological equivalence between geometric objects is not only theoretically fundamental, but also computationally useful. In many practical situations, such as modeling and visualizing the writhing of macro-molecular structures, complex shapes can only be approximated in a high performance computing environment. For these visualization approximations, establishing topological equivalence (in a broad sense including homeomorphism and ambient isotopy) plays a crucial role for both theoretical correctness and algorithmic efficiency. This topic lies in the emerging area of Computational Topology. I will start with an introduction for general audiences. Then I will present my research that provides the equivalence for knots, and for splines between their smooth and the associated piecewise linear structures.
