A myriad of design rules for what constitutes a "good" colormap can be found in the literature. Some common include order, uniformity, and high discriminative power. However, meaning many these terms is often ambiguous or open to interpretation. At times, different authors may use same term describe concepts rule described by varying nomenclature. These ambiguities stand way collaborative work, experiments assess characteristics colormaps, automated generation. In this paper, we review...

Pseudocoloring is one of the most common techniques used in scientific visualization. To apply pseudocoloring to a scalar field, field value at each point represented using sequence colors (called colormap). One principles applied generating colormaps uniformity and previously main method for determining has been application uniform color spaces. In this paper we present new evaluating feature detection threshold function across colormap. The crowdsourced studies direct evaluation nine three...

This article presents ColorMoves, an interactive tool that promotes exploration of scientific data through artist-driven color methods in a unique and transformative way. We discuss the power contrast visualization, design ColorMoves tool, tools application several science domains.

Continuous colormaps are integral parts of many visualization techniques, such as heat-maps, surface plots, and flow visualization. Despite that the critiques rainbow have been around well-acknowledged for three decades, still widely used today. One reason behind resilience is lack tools users to create a continuous colormap encodes semantics specific application concerned. In this paper, we present web-based software system, CCC-Tool (short Charting Colormaps) under URL https://ccctool.com,...

Scientists from the Climate, Ocean and Sea Ice Modeling Team (COSIM) at Los Alamos National Laboratory (LANL) are interested in gaining a deeper understanding of three primary ocean currents: Gulf Stream, Kuroshio Current, Agulhas Current & Retroflection. To address these needs, visual artist Francesca Samsel teamed up with experts areas computer science, climate statistics, perceptual science. By engaging an specializing color, we created colormaps that provide ability to see greater detail...

We introduce Artifact-Based Rendering (ABR), a framework of tools, algorithms, and processes that makes it possible to produce real, data-driven 3D scientific visualizations with visual language derived entirely from colors, lines, textures, forms created using traditional physical media or found in nature. A theory process for ABR is presented address three current needs: (i) designing better by making non-programmers rapidly design critique many alternative data-to-visual mappings; (ii)...

We present Bento Box, a virtual reality data visualization technique and bimanual 3D user interface for exploratory analysis of 4D ensembles. Box helps scientists engineers make detailed comparative judgments about multiple time-varying instances that up ensemble (e.g., group 10 parameterized simulation runs). The approach is to an organized set complementary volume visualizations juxtaposed in grid arrangement, where each column visualizes single instance row provides new view the from...

As the complexity of scientific data and needs to communicate science have grown, requirements for visualization design use become more sophisticated. We increasingly need effective ways communicating across multiple audiences, including non-experts in field. The challenges enriching representation moved from naive ideas making it "aesthetically attractive" profound constructs visual language: how enhance nuances data, support expressive visualizations that elicit different cognitive...

As a self-professed AI artist, Nina Rajcic presented an opportunity for us to explore curiosity regarding how artists have been developing process during boon brought on by transformer and generative tools. Although her journey has one of pursuing text as creative output, the nature transformers diffusion suggested relevance graphical outputs. The following interview did not disappoint in that pursuit.

Ocean salinity is a critical component to understanding climate change. Salinity concentrations and temperature drive large ocean currents which in turn global weather patterns. Melting ice caps lower at the poles while river deltas bring fresh water into worldwide. These processes slow currents, changing patterns producing extreme events disproportionally affect those living poverty. Analysis of presents unique visualization challenge. Important data are found narrow ranges, varying with...

Data physicalizations (3D printed terrain models, anatomical scans, or even abstract data) can naturally engage both the visual and haptic senses in ways that are difficult impossible to do with traditional planar touch screens immersive digital displays. Yet, rigid 3D produced today's most common printers fundamentally limited for data exploration querying tasks require dynamic input (e.g., sensing) output animation), functions easily handled We introduce a novel style of hybrid virtual +...

We describe explorations and innovations developed to help scientists understand an ensemble of large scale sim- ulations asteroid impacts in the ocean. The simulations were run determine characteristics asteroids that NASA should track, so communities at risk from impact can be given advanced notice. Of rel- evance CHI community are 1) hands-on workflow issues specific exploring ensembles scientific data, 2) such data with color, 3) examples multidisciplinary collaboration.

Computer graphics has an application in virtually every area of human activity. In this Special Issue, we focus on applications art and cultural heritage. For decades now played a role the digitization, restoration, conservation, presentation, communication our heritage as well providing new mediums for reflecting culture. There continues to be productive two-way channel between computer heritage—new techniques continue have positive impact understanding heritage, inspire innovations...

As a fascinating artist compelled by craftsmanship, Nathalie Miebach's prodigious art production spans across different practices and interests including sculpture, music, the intersection of art-science with visual articulation scientific observations. In reviewing her work to date, we noticed many themes that believed our readership might benefit from when considering for their own practices. We were curious find out more about process perspective. She had much say on matter as can be read...

Visualization research and practice that incorporates the arts make claims to being more effective in connecting with users on a human level. However, these are difficult measure quantitatively. In this paper, we present follow-on study use close reading, humanities method from literary studies, evaluate visualizations created using artistic processes [Bares 2020]. Close reading is studies we've previously explored as for evaluating visualizations. To an evaluation method, guide participants...

As computing capacity increases and data grows in both size complexity, we are capable of understanding our surroundings with increasing nuance. Visualizing this often-multivariate environmental presents complex visual scenes to be navigated, parsed, analyzed, communicated. We draw from the natural world artistic color theory present 1) a new system, designed establish an affective connection between big its original source material, 2) tool for extracting these workable palettes imagery, 3)...

Over decades and centuries, the practices of art science have diverged as separate disciplines and, driven by scrutiny opinions, sought to define what makes a great artist or scientist. It is not surprising, therefore, that many scientists remain unfamiliar with varied artistic contributions scientific advancement. Art-science case studies aren't encountered in our everyday work, but they can be highly suggestive approaches for creative thinking innovation. Today you readily find whose work...
