We introduce a novel liquid simulation approach that combines a spatially adaptive pressure projection solver with the Particle-in-Cell (PIC) method. The solver relies on a generalized version of the Finite Difference (FD) method to approximate the pressure field and its gradients in tree-based grid discretizations, possibly non-graded. We also present a data structure that connects the spatial subdivision of a quadtree/octree with the topology of its corresponding dual-graph.

In this Master's Thesis we studied new techniques for processing such data objects using an unusual approach to the geometric processing area: techniques for analyzing time series, such as scattering wavelets and recurrence plots. For shape retrieval problem, i.e., given a tridimensional mesh try finding other meshes that are visually similar, our method extract only one feature - Gaussian curvature and surface variation, for example - and organize it as a series using information given by Fiedler vector.

この交流プログラムの目的は、昔に中南米へ行きました和歌山の人の子孫に日本の文化を知ってもらうことです。和歌山の町と、生活と、観光場所を経験できるようなプログラムです。
