We are particularly interested in means of arbitrarily changing the appearance of real-world scenes without the use of physical interfaces such as glasses or other devices worn by the user. In this paper, we refer to such means as spatial displays. Typical examples of spatial displays include a system that can change the transparency or physical properties of buildings [Rekimoto, 2012] and a system that projects video images [Raskar, 2001]. However, those systems have restrictions such as requiring some kind of physical interface between the user and the scene or not being usable in a well-lit environment. Taking a different approach, we turned our attention to a natural phenomenon referred to as heat haze, in which the appearance of objects is altered by changes in the refractive index of air caused by differences in temperature distribution. We propose the atmoRefractor, a system that can generate and control heat haze on a small scale without an additional physical interface such as lenses. That locally controllable heat haze effect can be used to direct attention by changing the appearance of certain parts of scenes.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125746820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lachaud","doi":"10.1145/2787626.2792637","DOIUrl":"https://doi.org/10.1145/2787626.2792637","url":null,"abstract":"During a snowfall, the snow crystals accumulate on the ground and gradually form a complex porous medium constituted of air, water vapour, ice and sometimes liquid water. This ground-lying snow transforms with time, depending on the physical parameters of the environment. The main purpose of the digitalSnow project is to provide efficient computational tools to study the metamorphism of real snow microstructures from 3D images acquired using X tomography techniques. We design 3D image-based numerical models than can simulate the shape evolution of the snow microstructure during its metamorphism. As a key measurement, (mean) curvature of snow microstructure boundary plays a crucial role in metamorphosis equations (mostly driven by mean curvature flow). In our previous work, we have proposed robust 2D curvature and 3D mean and principal curvatures estimators using integral invariants. In short, curvature quantities are estimated using a spherical convolution kernel with given radius R applied on point surfaces [Coeurjolly et al. 2014]. The specific aspect of these estimators is that they are defined on (isothetic) digital surfaces (boundary of shape in Z3). Tailored for this digital model, these estimators allow us to mathematically prove their multigrid convergence, i.e. for a class of mathematical shapes (e.g. C3-boundary and bounded positive curvature), the estimated quantity converges to the underlying Euclidean one when shapes are digitized on grids with gridstep tending to zero. In this work, we propose to use the radius R of our curvature estimators as a scale-space parameter to extract features on digital shapes. Many feature estimators exist in the literature, either on point clouds or meshes (\"ridge-valley\", threshold on principal curvatures, spectral analysis from Laplacian matrix eigenvalues, . . . ). In the context of objects in Z3 and using our robust curvature estimator, we define a new feature extraction approach on which theoretical results can be proven in the multigrid framework.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122861294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
