“…This technique is similar to those applied to other spherical functions in bio-medical imaging [26], such as diffusion-tensor MRI [27], and provides a unique insight into the structure of the scattered field. This allows the user to explore the scattering efficiency of a particle in three-dimensions as a function of material and position ( Figure 9) and validate the effectiveness of MC integration (Figure 7).…”

Understanding the structure of a scattered electromagnetic (EM) field is critical to improving the imaging process. Mechanisms such as diffraction, scattering, and interference affect an image, limiting the resolution, and potentially introducing artifacts. Simulation and visualization of scattered fields thus plays an important role in imaging science. However, EM fields are highdimensional, making them time-consuming to simulate, and difficult to visualize. In this paper, we present a framework for interactively computing and visualizing EM fields scattered by micro and nano-particles. Our software uses graphics hardware for evaluating the field both inside and outside of these particles. We then use Monte-Carlo sampling to reconstruct and visualize the three-dimensional structure of the field, spectral profiles at individual points, the structure of the field at the surface of the particle, and the resulting image produced by an optical system.

“…Glyphs can be made to contain even more information by using data plots to determine their shapes; some examples are whisker, star, and parallel coordinate plots. Numerous papers have examined the effective use of glyph representations for various applications [2,3,4]. Yet these papers do not consider the unconscious associations that visual attributes -such as shape -may hold.…”

In visualizations of large multivariate data sets, discrete data can be effectively represented using glyphs. Glyphs have the advantage of allowing for rapid visual comparison, using differing visual dimensions to represent the different variables in the data. Some types of glyphs accommodate even more variables by using shape to represent the data. Yet the characteristics of these shapes may have underlying perceptual meanings. The purpose of this study was to determine whether certain shape characteristics are commonly viewed as good or bad. We conducted a study using two methods to gather data: a traditional survey, and a casual game. The results of this study strongly suggest that there are certain shape characteristics that are generally perceived as positive/negative, although they are not necessarily what might be expected.

“…The visual attributes of glyphs can be 3D position, color, size, shape, texture, and so forth. Glyph-based visualization of arbitrary data in real-time virtual environments is addressed in Nagel [2005], Feng et al [2009], and Ropinski et al [2011]. Although many other types of data visualization exist, such as volumetric rendering based on voxels [Kratz et al 2006] or surface visualizations based on polygons or splats [Zhang and Kaufman 2006], the issues addressed in this article are aimed at 3D glyph-based visualizations.…”

On the Benefits of Using Constant Visual Angle Glyphs in Interactive Exploration of 3D Scatterplots

Visual exploration of clouds of data points is an important application of virtual environments. The common goal of this activity is to use the strengths of human perception to identify interesting structures in data, which are often not detected using traditional, computational analysis methods. In this article, we seek to identify some of the parameters that affect how well structures in visualized data clouds can be identified by a human observer. Two of the primary factors tested are the volumetric densities of the visualized structures and the presence/absence of clutter around the displayed structures. Furthermore, we introduce a new approach to glyph visualization-constant visual angle (CVA) glyphs-which has the potential to mitigate the effect of clutter at the cost of dispensing with the common real-world depth cue of relative size. In a controlled experiment where test subjects had to locate and select visualized structures in an immersive virtual environment, we identified several significant results. One result is that CVA glyphs ease perception of structures in cluttered environments while not deteriorating it when clutter is absent. Another is the existence of threshold densities, above which perception of structures becomes easier and more precise. ACM Reference Format:Rasmus Stenholt. 2014.
