Two VCL papers to be presented at SIGGRAPH 2019

Two VCL papers to be presented at SIGGRAPH 2019

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.

Annie Dai successfully defends master's thesis

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.

Would a sample by any other name smell as sweet?

Would a sample by any other name smell as sweet?

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.

Let’s Do the Time Warp Again

Let’s Do the Time Warp Again

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.

Xi Deng successfully defends master's thesis

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.

Augmented reality research tackles blurry vision

Augmented reality research tackles blurry vision

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.

New research lets artists create more realistic and controllable CGI

New research lets artists create more realistic and controllable CGI

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.

"Smart" Spray Paint Cans Developed by VCL Professor and Team

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.
