A staggering six papers affiliated with the VCL were presented at the Eurographics Symposium on Rendering in Strasbourg, France last week. All bore the name of VCL Director Wojciech Jarosz, who co-presented his work “Orthogonal array sampling for Monte Carlo rendering” with advisee and recent Bachelor’s graduate Afnan Enayet. In addition, VCL PhD student Kate Salesin presented her work “Combining point and line samples for direct illumination” and past VCL postdoc Gurprit Singh presented his work “Fourier analysis of correlated Monte Carlo importance sampling” at the conference.
Members of the VCL spent this past Saturday illuminating the magical world of computer graphics to some of the community’s younger folk. The event was a Dartmouth community outreach program called Science Day, where graduate students across campus teach kids about their area of research and lead simple hands-on activities.
VCL student Neerja Thakkar ‘19 was one of six Dartmouth students awarded a government-funded Fulbright scholarship for the coming year. Her senior thesis focused on “rendering synthetic data for deep learning and computer vision tasks.” After graduation, she plans to travel abroad to Spain and continue her research in the computational imaging lab at the Universidad de Zaragoza.
Past and present VCL members made the short trip to MIT in order to attend the New England Symposium on Graphics this April. VCL Director Wojciech Jarosz presented a talk titled “Towards Point-and-Shoot Rendering: Robust and Automatic Light Transport Algorithms for Humans and Machines.”
As the snow thaws, the VCL welcomes the following new students to the lab. Several join us from around the globe!
VCL member Annie Dai successfully defended her master’s thesis, titled “Computational Fabrication – String Art.” Her thesis proposed a technique for creating realistic string art, a form of artwork where artists wind strings around pins, from a reference image.
CS Professor Wojciech Jarosz has received an NSF CAREER Award! The NSF Program “offers the National Science Foundation’s most prestigious awards in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research.”
A new study led by Gurprit Singh of Dartmouth’s Visual Computing Lab presents an in-depth exploration of sampling strategies commonly used to create computer-generated images. This research highlights some previously unknown strengths and weaknesses of those strategies, and proposes a few simple tricks to tame their weaknesses.
A new study co-authored by Visual Computing Lab Director Wojciech Jarosz builds on his previous work simulating how light is scattered, refracted, and reflected. Rather than assume the speed of light is infinite, as one usually would in computer graphics, this work incorporates the true speed of light in order to visualize how the light bounces around a scene filled with particles and surfaces.
VCL student Xi Deng successfully defended her master’s thesis, titled “Photon Surfaces: Render Volume Robustly with Unbiased Density Estimators,” bright and early on a Friday morning. Her work continued a thread of research from Dartmouth’s Visual Computing Lab on techniques for simulating complex particle-based materials such as fog, clouds, fire, smoke, and stained glass.
Fresh research from Dartmouth’s Visual Computing Lab demonstrates how augmented reality could be used to help people with reduced vision read signs in their environment. The team not only designed an application able to detect and display enhanced text via Microsoft’s HoloLens, they conducted a behavioral experiment to validate their system’s effectiveness.
A new theory based on the physics of cloud formation and neutron scattering could help animators create more lifelike movies, according to a Dartmouth-led study. Software developed using the technique focuses on how light interacts with microscopic particles to develop computer-generated images.
Xiaoting Zhang joins VCL as a postdoc with Professor Whiting.
Prof. Wojciech Jarosz, together with Romain Prévost (ETH Zurich/Disney Research Zurich), Alec Jacobson (ETH Zurich/Columbia University), and Olga Sorkin-Hornung (ETH Zurich) have developed a computationally-assisted spray painting system that allows novices to spray paint accurate reproductions of photographs as large murals. The research appears in April's issue of the journal Computers & Graphics.
Congratulations to Liane Makatura! She is among eight undergraduate students selected internationally to win the Adobe Research Women-in-Technology Scholarship.
Members of VCL attended the Symposium on Computational Fabrication, held at MIT this week. PhD student Athina Panotopoulou presented in the poster session, highlighting recent work on Perceptual Models of Preference in 3D Printing Direction.
The Daily Mail reports on a new analysis by Srivamshi Pittala, Emily Whiting and Hany Farid that confirms the authenticity of the famous backyard photo of Lee Harvey Oswald. See the whole article at the Daily Mail.
Research lead by VCL's Prof. Jarosz in collaboration with Disney Research was presented at Pacific Graphics 2015 last week, where it won the Best Paper Award. The paper describes a novel method for projecting color images using a white light source and an optical device with no colored components—consisting solely of one or two prisms and two masks printed on transparencies.
