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.
Two new studies continue a long thread of research from the VCL on estimating how light bounces around light-scattering environments such as smoke or fog. The results will be presented at SIGGRAPH in Los Angeles this summer.
A new State of the Art report co-authored (among others) by past VCL member Gurprit Singh and VCL Director Wojciech Jarosz reviews a long thread of research on point sampling distributions for computer graphics.
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.
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.
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.
