We leverage data from two different sources: real-world data acquired with an effective exposure time of less than 2 picoseconds, using an ultra-fast imaging technique termed femto-photography, and a transient renderer based on ray-tracing. We explore the effects of time dilation, light aberration, frequency shift and radiance accumulation by modifying existing models of these relativistic effects to take into account the time-resolved nature of light propagation. Unlike previous works, we do not impose limiting constraints in the visualization, allowing the virtual camera to explore freely a reconstructed 3D scene depicting dynamic illumination. Moreover, we consider not only linear motion, but also acceleration and rotation of the camera. We further introduce, for the first time, a pinhole camera model into our relativistic rendering framework, and account for subsequent changes in focal length and field of view as the camera moves through the scene. info:eu-repo/grantAgreement/ES/MINECO/Lightslice info:eu-repo/grantAgreement/EC/FP7/288914/EU/Vanquishing fear and apathy through E-inclusion: \nPersonalised and populated Realistic Virtual Environments for clinical, home and mobile platforms/VERVE info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.542 2015 COMPUTER SCIENCE, SOFTWARE ENGINEERING 17 / 106 = 0.16 2015 Q1 T1 0.806 2015 Computer Networks and Communications 2015 Q1 Computer Graphics and Computer-Aided Design 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0003-0060-7278 Masia, Belen Universidad de Zaragoza Velten, Andreas Barsi, Christopher Raskar, Ramesh (orcid)0000-0002-7503-7022 Gutierrez, Diego Universidad de Zaragoza 5007 570 Universidad de Zaragoza Dpto.
