"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.

The group wanted to create a way to allow untrained users to spray paint large graffiti murals. To accomplish this, they instrumented a physical spray paint can with an actuator to turn it on/off and QR codes to track its location. A nearby computer analyses the position of the spray can as well as the current painting on the wall/canvas, and automatically turns the spray on or off. In essence, the spray can "knows" what it wants to paint, and the user just has to wave it around, seeing the image appear in front of them.

For more technical details, including a preprint of the publication and a demonstration video, check out the project page on Prof. Jarosz's website.

Several news agencies are also reporting on the research:

Perceptual Models of Preference in 3D Printing Direction

Authors: Xiaoting Zhang, Xinyi Le, Athina Panotopoulou, Emily Whiting & Charlie C.L. Wang

Research from VCL's Prof. Whiting and PhD student Athina Panotopoulou was presented at SIGGRAPH Asia 2015 in Kobe, Japan. The work was in collaboration with researchers from the Chinese University of Hong Kong . The paper introduces a perceptual model for determining 3D printing orientations. Additive manufacturing methods involving low-cost 3D printers often require robust branching support structures to prevent material collapse at overhangs. Although the designed shape can successfully be made by adding supports, residual material remains at the contact points after the supports have been removed, resulting in unsightly surface artifacts. To prevent the visual impact of these artifacts, the paper presents a training-and-learning method to find printing directions that avoid placing supports in perceptually significant regions.

VCL research wins Best Paper award at Pacific Graphics 2015

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. In the future, the prototype technology could be refined to provide improved spectral color reproduction or increased light efficiency compared to current techniques.

MS Digital Arts Students at SIGGRAPH

MS Digital Arts students, Runi Goswami and Tim Tregubov, presented their thesis work at SIGGRAPH 2015 in LA. Titled "FrameShift: Shift Your Attention, Shift the Story", the project introduces a novel framework for graphic storytelling. It uses reader attention, as measured by eye-gaze fixation, to introduce subtle narrative and graphic changes and in turn change readers’ belief states over time. The thesis was advised by Professor Lorie Loeb, and was presented as both a Studio Talk and demoed in the poster session at SIGGRAPH.

New MS Degree in CS with a concentration in Digital Arts

Are you interested in working at the intersection of computer science, arts and design?  

Introducing a new MS Degree in CS with a concentration in Digital Arts Program at Dartmouth College!

Open to students from a wide variety of undergraduate majors in areas related to arts, design and technology, students in the new CS/DA program complete a mix of computer science courses, digital arts courses, and research/thesis. They experience a rigorous and focused computer science education, foundational courses in digital arts, and a deep dive into a research topic within the areas of visual computing and digital arts (e.g. computer graphics, HCI, digital fabrication, digital art and media, computer vision, VR and AR).

Courses required for the degree will depend on the background of each student. All students will take 18 credits to graduate–9 courses plus 9 credits in research and thesis writing. For more information: www.cs.dartmouth.edu

Students accepted into the program are eligible for half and full scholarships and can gain additional experience through work in the DALI Lab.

Application Deadline: April 15, 2015

Notifications of Acceptance: May 1, 2015
