Cyclidic nets are a discretization of orthogonal nets, closely related to the discretization as circular nets. In Euclidean 3-space they discretize curvature line parametrized surfaces resp. triply orthogonal coordinate systems. The application allows to extend (fixed) 2- and 3-dimensional circular nets to cyclidic nets, where the extension is uniquely determined by the choice of an orthonormal 3-frame at one vertex. The user may change this frame interactively and explore the corresponding change of the cyclidic net. The program also allows to examine single cyclidic patches and whole Dupin cyclides.
