Time-varying volume visualization

Volume rendering is a very active research field in Computer Graphics because of its wide range of applications in various sciences, from medicine to flow mechanics. In this report, we survey a state-of-the-art on time-varying volume rendering. We state several basic concepts and then we establish several criteria to classify the studied works: IVR versus DVR, 4D versus 3D+time, compression techniques, involved architectures, use of parallelism and image-space versus object-space coherence. We also address other related problems as transfer functions and 2D cross-sections computation of time-varying volume data. All the papers reviewed are classified into several tables based on the mentioned classification and, finally, several conclusions are presented.Preprin

Coherencia de objetos, coherencia de rayos y paralelismo, en la aceleración del trazado de rayos

El problema central que se ha abordado en esta tesis consiste en el análisis, desarrollo e implementación de algoritmos que permitan acelerar el método clásico de generación de imágenes foto-realistas a través de las técnicas de trazado de rayos. Para ello, se ha pretendido estudiar los principales métodos de aceleración presentados hasta este momento y proponer una nueva alternativa que, teniendo presentes los beneficios esperados de la aplicación individual de cada propuesta, ofrezca además nuevas ventajas fruto de la unión, en una alternativa conjunta, de las diferentes propuestas individuales
