Color is fundamental component of the world around us and our experience. It plays a key role in the understanding of our environment, from science and engineering to design and art … but how does it work ? And, what makes digital color different?
This September, renown color and visualization expert Theresa-Marie Rhyne will visit Virginia Tech to share her perspective on the theory and practice of color. With years of experience building notable visualization programs and as the author of the recent book, Applying Color Theory to Digital Media and Visualization, Theresa-Marie will visit with faculty and students as well as give a lecture to a graduate Computer Science class and to the broader University Community. Her talk is scheduled for 1 pm Monday Sept 23rd in Torgersen Hall 1100.
“Color Fundamentals for Digital Content Creation & Visualization”
Abstract: We provide an overview of the fundamentals of color theory and approaches to color selection for visualization and exploration. Our journey includes the introduction to the concepts of color models and harmony, a review of color vision principles, the defining of color gamut, spaces and systems, and highlighting online and mobile apps for performing color analyses of digital media. We feature concepts from art and design such as extending the fundamentals of the Bauhaus into digital media as well as review color perception and appearance principals from vision and visualization researchers and practitioners. Newly emerging trends in automated color selection and deep learning colorization are also noted.
About the Instructor: Theresa-Marie Rhyne is an expert in the field of computer-generated visualization and a consultant who specializes in applying artistic color theories to visualization and digital media. Her book on “Applying Color Theory to Digital Media and Visualization” was published by CRC Press in 2016 and is recognized by librarians and color professionals as a best selling reference. Her short course at the premiere conference on computer graphics and interactive techniques, SIGGRAPH 2019, was standing room only. Theresa-Marie has consulted with the Stanford University Visualization Group on a color suggestion prototype system, the Center for Visualization at the University of California at Davis and the Scientific Computing and Imaging Institute at the University of Utah on applying color theory to ensemble data visualization. Prior to her consulting work, Theresa-Marie founded two visualization centers: (1) the United States Environmental Protection Agency’s Scientific Visualization Center and (2) the Center for Visualization and Analytics at North Carolina State University.
A new collaboration is underway across the Commonwealth of Virginia as the CLAS-12 instrument comes online at Jefferson National Labs: The Center for Nuclear Femtography is a Commonwealth-funded center dedicated to imaging the heart of the atom: the nucleon. In 2018, researchers from around the state were called to the first annual Symposium on Nuclear Femtography, held in Charlottesville; later that year, a round of pilot projects were funded to build partnerships across universities and across disciplines.
As a trans-disciplinary concept, the Center for Nuclear Femtography (CNF) does not just target Virginia Physicists: such collaborations are made from experts all across the country and the world, including computer scientists, statisticians, mathematicians, and mechanical engineers to name a few. ARC faculty Nicholas Polys and Srijith Rajamohan are Co-PIs on two of these CNF pilot projects: “Visualizing Femtoscale Dynamics” and “Next-generation Visual Analysis Workspace for Multidimensional Nuclear Femtography Data”. Phase One is completing with several exchange visits, meetings and seminars, and a first set of deliverables (public soon).
The VT Center for Human Computer Interaction (CHCI) published this nice summary of our high impact work at the biggest graphics conference in the world! Dr. Polys represented ARC’s innovations in visual computing:
3D Models are increasingly valuable for safety and for scenery. ARC and CGIT collaborated to host researchers considering scenic resources inventory, including protocols and results for the Appalachian Trail:
Virginia Tech’s Advanced Research Computing (ARC) group in the Division of Information Technology offers shared high-performance computing resources to support the Virginia Tech research community, as well as non-research users who need more high-end computing power than departmental systems can provide. Offering high-performance computing services on ARC’s clusters means the computational processing, management, and data storage needs are all serviced remotely.
We are looking forward to seeing you at our Annual HPC Day event March 24 from 10am-5pm!
The event includes: a keynote by James Ahrens from LANL, a machine learning workshop, and faculty and student presentations.
Keynote: “Supercharging the Scientific Process Via Data Science at Scale”
Dr. James Ahrens is a senior research scientist at the Los Alamos National Laboratory (LANL). He is the founder and design lead of ParaView, a widely adopted visualization and data analysis package for large-scale scientific simulation data ( http://paraview.org). ParaView has had an extremely positive impact on the large-scale data analytic capabilities available to simulation scientists around the world. Dr. Ahrens graduated in 1989 with a B.S. in computer science from the University of Massachusetts and in 1996 with a Ph.D. in computer science from the University of Washington. At LANL, he is part of a data science team of twenty staff, postdocs and students. He is also a national leader of programmatic initiatives important to the United States Department of Energy’s National Nuclear Security Administration and Office of Science. Dr. Ahrens is the Data Analysis and Visualization lead for the U.S. Exascale Computing Project and the general chair for this year’s IEEE Scientific Visualization conference to be held in Phoenix, AZ in early October.
ARC member Nicholas Polys helped organize a session at the CHCI Workshop Technology on the Trail on March 2-3. The session “From Experience to Abstraction and Back Again” discussed the challenges and opportunities for citizen science, especially the use of uncertain data to build new scientific models. The event was covered with an article in the Roanoke Times!
