critical points

Paraview is an open-source scientific visualization application. Topology Toolkit, short as TTK, as a plugin in ParaView helps to do some calculations and visualization, like getting the critical point, contour curves and segmentation of the shape. Above examples learned from the workshop. ParaView itself also has some special geometry models, like minimal surface, Boy's surface, spiral surfaces et. al.
