This paper presents a novel framework for visualizing volumetric data specified on complex
polyhedral grids, without the need to perform any kind of a priori tetrahedralization. These …

This paper presents the Element Visualizer (ElVis), a new, open-source scientific
visualization system for use with high-order finite element solutions to PDEs in three …

We argue that there is a need for substantially more research on the use of generative data
models in the validation and evaluation of visualization techniques. For example, user …

The study on spatial database outsourcing has been spotlighted with the development of
cloud computing. Therefore, researches for protecting location data privacy in outsourced …

The parallel vectors (PV) operator is a feature extraction approach for defining line‐type
features such as creases (ridges and valleys) in scalar fields, as well as separation …

We present a GPU-based ray-tracing system for the accurate and interactive visualization of
cut-surfaces through 3D simulations of physical processes created from spectral/hp high …

Character recognition is one of important applications for pattern recognition. Feature
extraction is the most important problem in character recognition. In this paper, we have …

This paper describes a new volume rendering system for spectral/hp finite-element methods
that has as its goal to be both accurate and interactive. Even though high-order finite …

In NURBS-based isogeometric analysis, the basis functions of a 3D model's geometric
description also form the basis for the solution space of variational formulations of partial …

Finite element (FE) models are frequently used in engineering and life sciences within time-
consuming simulations. In contrast with the regular grid structure facilitated by volumetric …
