Description |
One of the most successful method to quantify the structures in the Cosmic Web is the Minkowski Functionals. We have developed a powerful diagnostic SURFGEN, a method to calculate the Minkowski Functionals and shapefinders (ratio of Minkowski Functionals) using triangulated polyhedral surface (contours). The triangulated polyhedral surface (contour) is generated from a discrete data set using Marching cube (Marching square) algorithm. Applying SURFGEN to different data sets we obtain interesting results related to the geometry, morphology and topology of the large scale structure. |
