Jan van Eyck's Perspectival System Elucidated Through Computer Vision

Gilles Simon
2021 Proceedings of the ACM on Computer Graphics and Interactive Techniques  
However, an a-contrario analysis of the vanishing points in five of his paintings, realized between 1432 and 1439, unveils a recurring fishbone-like pattern that could only emerge from the use of a polyscopic  ...  This discovery makes van Eyck the father of today's immersive and nomadic creative media such as augmented reality and synthetic holography.  ...  In order to distinguish between the references of the Supplementary Material and those of the main text (some of which are also cited in the Supplementary Material) the first are preceded by the letter  ...

Energized Rigid Body Fracture

Xiaokai Li, Sheldon Andrews, Ben Jones, Adam Bargteil
2018 Proceedings of the ACM on Computer Graphics and Interactive Techniques  
Frames from an animation of an unfortunate and hollow, yet energetic, bunny fracturing on the ground. Compelling animation of fracture is a vital challenge for computer graphics.  ...  Our approach computes the energy stored in these constraints when they are broken, and reintroduces it to the system as kinetic energy.  ...  Also, rather than computing a change in the velocities of all bodies in the system, v, we instead take a more pragmatic approach and compute an impulse based on the mass of the participating bodies and  ...

Rethinking Model-Based Gaze Estimation

Harsimran Kaur, Swati Jindal, Roberto Manduchi
2022 Proceedings of the ACM on Computer Graphics and Interactive Techniques  
One shortcoming of black-box, end-to-end methods, though, is that any unexpected behaviors are difficult to explain.  ...  In addition, there is always the risk that a system trained with a certain dataset may not perform well when tested on data from a different source (the "domain gap" problem.)  ...  The content is solely the responsibility of the authors and does not necessarily represent the official views of the National Institutes of Health.  ...

Lossy Geometry Compression for High Resolution Voxel Scenes

Remi van der Laan, Leonardo Scandolo, Elmar Eisemann
2020 Proceedings of the ACM on Computer Graphics and Interactive Techniques  
Furthermore, we show that our method is complementary to other state of the art SVDAG optimizations, and has a negligible effect on real-time rendering performance.  ...  We test our compression strategy on several standard voxel datasets, where we obtain memory reductions of 10% up to 50% compared to a standard SVDAG, while introducing an error (ratio of modified voxels  ...  The Crytek Sponza, San Miguel and Hairball scenes were obtained from Morgan McGuire's Computer Graphics archive.  ...
