Visual Analytics (VA) is an emerging field that provides automated analysis of large and complex data sets via interactive visualization systems in an effort to facilitate fruitful decision making. VA is a collaborative process between the human and the machine. In this paper, we present a multifaceted overview of this human-computer collaboration. The system facet contains everything about the...

Typically, flow volumes are visualized by defining their boundary as iso-surface of a level set function. Grid-based level sets offer a good global representation but suffer from numerical diffusion of surface detail, whereas particlebased methods preserve details more accurately but introduce the problem of unequal global representation. The particle level set (PLS) method combines the advanta...

An accurate assessment of the role of solar variability is a key step toward a proper quantification of natural and anthropogenic climate change. To this end, climate models have been extensively used to quantify the solar contribution to climate variability. However, owing to the large computational cost, the bulk of modeling studies to date have been performed without interactive stratospheri...

An interactive surface editing framework that is well suited to the needs of geophysical modelers and interpreters is described. This surface editing framework allows a non-expert user to quickly create complicated surfaces by combining two simple concepts: deformation and cutting. Deformations change the geometry of a surface and allow a user to model continuous geologic horizons. Cutting chan...

This paper presents a new data structure for light field rendering, which resembles a Star Trek holodeck in form and function. The grid on a holodeck section acts as a fourdimensional rendering target for a ray tracing algorithm, whose goal is to update an interactive display. A holodeck server coordinates separate ray evaluation and display processes, optimizing disk and memory usage. Holodeck...

Metaballs are a useful technique to model blobby surfaces. Because metaballs define an implicit surface, rendering is difficult. We seek to render the surface directly via ray-casting, to precisely locate the isosurfaces and preserve the concise representation of the surface. To perform this rendering at interactive rates on dynamic data, we will use acceleration structures for fast surface cal...

this paper was aimed to address the modeling of effective thermal conductivity and viscosity of carbon structured nanofluids. response surface methodology, d_optimal design (dod) was employed to assess the main and interactive effects of temperature (t) and weight percentage (wt %) to model effective thermal conductivity and viscosity of multi wall and single wall carbon nanotube, cvd and rgo g...

In computer aided design (CAD), the availability of many types of surface editing which ease creating the geometric models is important. This paper describes a wavelets-based mulresolution representation for endpoint-interpolating cubic B-spline surface and algorithms to support the surface editing at different scales, allowing structural features (global shape) deformations as well as detail f...

Several recent publications introduce user interface prototypes with non-planar interactive surfaces. Using our own prototype Curve featuring a large vertically curved interactive surface, we want to explore video conferencing and remote collaboration scenarios on non-planar interactive surfaces. We discuss the factors framing, mobility, conception of space and interface compatibility, which mi...
