Simulations of models, in all different areas, is an expanding, attractive line of work. More and more applications are taking advantage of the improvements in technology and knowledge in this field, thus achieving results that would have been impossible to achieve with a real model, or foreseeing facts that otherwise would have been encountered too late in(More)
We present a sequential mosaicing algorithm for a calibrated rotating camera which can for the first time build drift-free, consistent spherical mosaics in real-time, automatically and seamlessly even when previously viewed parts of the scene are re-visited. Our mosaic is composed of elastic triangular tiles attached to a backbone map of feature directions(More)
The rate of the spread and shape of a forest fire front is a problem that has not been thoughtfully studied from a computer graphics perspective. Here, using physically based computer graphics modeling, we propose a model for the simulation of wildland fires over 3D complex terrain. The model is based on conservation laws of energy and species, which(More)
This paper presents the parallelization of techniques for the design of reflector shapes from prescribed optical properties (far-field radiance distribution), geometrical constraints and, if available, a user-given initial guess. This is a problem of high importance in the field of Lighting Engineering, more specifically for Luminaire Design. Light(More)
This paper stems from the educational experience of the Research and Development (R+D) The lecturing of Computer Graphics group subjects is based on the learning methodology of problem-solving. Human-Computer Interaction, however, is taught following the behaviorist paradigm which, due to its informative nature, is based on master classes. The paper sets(More)
GIGA (the Advanced Computer Graphics Group from the University of Zaragoza) has developed two packages, code-named ALEPH and SICARA3D. Those systems are capable of both calculating light distribution in complex environments, based on a rigorous simulation of the physical phenomena involved, and visualizing the results in a photorealistic way, including(More)
