Particle-based simulation methods are used to model a wide range of complex phenomena and to solve time-dependent problems of various scales. Effective visualization of the resulting state should communicate subtle changes in the three-dimensional structure, spatial organization, and qualitative trends within a simulation as it evolves. We take steps toward understanding and using advanced shading models in the context of interactive particle visualization. Specifically, the impact of ambient occlusion and physically based diffuse interreflection is investigated using a formal user study. We find that these shading models provide additional visual cues that enable viewers to better understand subtle features within particle datasets. We also describe a visualization process that enables interactive navigation and exploration of large particle datasets, rendered with illumination effects from advanced shading models. Informal feedback from application scientists indicates that the results of this process enhance the data analysis tasks necessary for understanding complex particle datasets.

What determines the color appearance of real objects viewed under natural conditions'? The light reflected from different locations on a single object can vary enormously. This variation is enhanced when the material properties of the object are changed from matte to glossy. Yet humans have no trouble assigning a color name to most things. We studied how people perceive the color of spheres in complex scenes. Observers viewed graphics simulations of a three-dimensional scene containing two spheres, test and match. The observer's task was to adjust the match sphere until its color appearance was the same as that of the test sphere. The match sphere was always matte, and observers varied its color by changing the simulated spectral reflectance function. The surface gloss of the test spheres was varied across conditions. The data show that for fixed test sphere body reflectance, color appearance depends on surface gloss. This effect is small, however, compared to the variation that would be expected if observers simply matched the average of the light reflected from the test.

One of the most important, still unsolved problems in computer graphics is the generation of predictive imagery, i.e., images that represent perfect renditions of reality. Such perfect images are required in application areas like Virtual Prototyping for making reliable decisions in the costly design development of novel products like cars and airplanes. Recently, measured material properties received significant attention since they enable generation of highly accurate images that appear to be predictive at a first glance. In this work we investigate the degree of realism that can be achieved using measured bidirectional texture functions (BTFs) by comparing photographs and rendered images at two scales. To analyze the realism of rendered images at a coarse scale, we compare the light distribution resulting from standard materials to the one from measured BTFs by automatic procedures. At a fine scale, accurate reproduction of material structures is checked by a psychophysical study. Our results show that measured BTFs lead to much more accurate results than standard materials at both scales. Copyright © 2006 by the Association for Computing Machinery, Inc.

Oriented textures and smooth flows are common texture patterns in visualization, non-photorealistic rendering, and graphical depictions of 3D objects. While these patterns have been partially studied in terms of their contribution to the inference of 3D shape, early visual aspects of their perception, and in particular, their segregation and perceptual organization into coherent parts, have been largely ignored. Here we explore the perception of such smoothly varying oriented textures and flow patterns in order to provide several insights and formal constraints to their constructive use in graphics and visualization. First, we challenge the view that salient perceptual singularities between perceptually coherent regions in orientation-defined textures (ODTs) are tightly dependent upon outstanding contrasts (a.k.a. gradients, or discontinuities) in their local orientation. Unfortunately, this widely accepted view has emerged from two decades of psychophysical research into orientation-based texture segregation (OBTS) which focused mostly on piecewise constant ODTs. A more general inquiry, however, into ODTs of smoothly varying orientation, reveals new perceptual phenomena. In particular, as we show here, completely smooth oriented patterns exhibit striking perceptual singularities that often are mistaken for discontinuities, and are neither predictable from orientation contrasts nor are they detectable by popular segmentation algorithms (Fig. 1). In contrast to existing perceptual models, we then show that our previous (differential) geometric analysis of oriented patterns [BenShahar and Zucker 2003] can be extended into a new theory that fully predicts the observed perceptual singularities using a novel computational "perceptual singularities measure" (PSM): PSM(x,y)= ∏κT2+κN2>τ(Ridges[κN(x,y) 2/κT(x,y)2 + κN(x,y) 2]) (1) where κT(x,y) and κN(x,y) are the tangential and normal curvatures of the pattern, Ridges() returns the set of ridge points of its argument functi

perception of Image Motion during Head Movement 06

Perception of Image Motion during Head Movement

Previous studies have shown that self-motion has an inhibiting effect on concurrent 3D motion perception. To investigate whether self-motion similarly impairs concurrent image motion perception, we examined human perception of head-referenced horizontal image motion during head movement. The displayed stimulus was composed of a checkerboard image in a head mounted display oscillating from side to side at four frequencies (0.25, 0.5, 1 and 2 Hz) with half peak-to-peak amplitudes ranging from 0° to 5.64. Eight observers rated the magnitude of the checkerboard motion while either rotating their head about a vertical axis (yaw), about a horizontal axis (pitch), or holding it still. For all image oscillation frequencies, perceptual sensitivity to image motion amplitude was reduced during both horizontal and vertical head movements (mean reduction: 0.44 and 0.17, respectively). In contrast, perceptual bias was affected only at 2 Hz (mean shift: -9.9% and -12.2% of the full image motion amplitude for horizontal and vertical head movements, respectively). The results indicate that head movement causes gain reductions in motion magnitude estimation at image oscillation frequencies &le1 Hz. At an oscillation frequency of 2 Hz, head movement produces both a gain reduction and a bias shift. Virtual environment developers could take advantage of such effects by relaxing requirements for image stability as well as motion fidelity during head movement.

In recent work [4,2], we have discovered that people are able to make surprisingly accurate judgments about egocentric distances in an immersive virtual environment (IVE) in the special case that the IVE represents a high fidelity model of the same physical space that the user is actually occupying, and the user has been able to unambiguously verify this by viewing the real space prior to donning the display upon which the corresponding virtual environment is presented. Through followup experiments in multiple locales, we have verified that the key factor enabling this distance perception accuracy is fact of co-location, rather than any particular characteristics of the physical environment [1]. One possible interpretation of these intriguing results is that observers are better enabled to make accurate judgments of egocentric distance in an IVE when they are when they are cognitively 'immersed' or 'present' in the IVE - i.e. when they readily accept the virtual environment as being 'equivalent' to the real world and are therefore prepared to act in the virtual world in the same way that they act in the real world [3]. However, another interpretation is also possible: it could be that people are able to make accurate judgments of egocentric distances in a virtual environment when they know that it exactly corresponds to a recently viewed real environment because they are able to form a metrically accurate mental model of the spatial structure of the real environment from their brief exposure to it, so that when they are subsequently presented with the virtual environment they simply calibrate their mental model of distances in the IVE to be consistent with their remembered model of the corresponding real environment. In order to disambiguate between the 'presence' hypothesis and the 'spatial memory' hypothesis, we conducted the following study. Using a between-subjects design, we asked observers to make judgments of egocentric distance via blind walking in a real ro

Although a wide range of virtual reality (VR) systems are in use, there are few guidelines to help system and application developers select the components most appropriate for the domain problem they are investigating. Using the results of an empirical study, we developed such guidelines for the choice of display environment for four specific, but common, volume visualization problems: identification and judgment of the size, shape, density, and connectivity of objects present in a volume. These tasks are derived from questions being asked by collaborators studying Cystic Fibrosis (CF). We compared user performance in three different stereo VR systems: (1) head-mounted display (HMD);(2) fish tank VR (fish tank);and (3) fish tank VR augmented with a haptic device (haptic). HMD participants were placed "inside" the volume and walked within it to explore its structure. Fish tank and haptic participants saw the entire volume on-screen and rotated it to view it from different perspectives. Response time and accuracy were used to measure performance. Results showed that the fish tank and haptic groups were significantly more accurate at judging the shape, density, and connectivity of objects and completed the tasks significantly faster than the HMD group. Although the fish tank group was itself significantly faster than the haptic group, there were no statistical differences in accuracy between the two. Participants classified the HMD system as an "inside-out" display (looking outwards from inside the volume), and the fish tank and haptic systems as "outside-in" displays (looking inwards from outside the volume). Including haptics added an inside-out capability to the fish tank system through the use of touch. We recommend an outside-in system because it offers both overview and context, two visual properties that are important for the volume visualization tasks we studied. In addition, based on the haptic group's opinion (80% positive) that haptic feedback aided comprehe
