Geometric modeling at ICIMAF

Abstract:

In this talk an overview of the results on geometric modeling of the Group of Geometry at ICIMAF is given. The particular emphasis is placed on subdivision techniques, segmentation of triangulated surfaces and isogeometric analysis.

Among our results on subdivision, we show the advantages of using subdivision curves to approximate the boundary of an object within a digital image. Furter, a new scheme to generate subdivision curves on triangulated surfaces is included.

Concerning the segmentation of triangulated surfaces, a convenient sampling strategy is presented to obtain low dimensional embeddings that reduce the computational cost.

In the context of isogeometric analysis (IgA) two results are briefly presented. The first one is the solution of the wave propagation problem along plate structures using the semianalytic method with IgA approach. The second one is related with the problem of constructing an injective map that parametrizes the physical region where a PDE has to be solved.
