Hardware and software improvements of volume splatting
Vergés Garcia, Eduard; Grau Carrión, Sergi; Tost Pardell, Daniela (2006-05)
Report de recerca
Accés obertThis paper proposes different hardware-based acceleration of the three classical splatting strategies: emph{composite-every-sample}, emph{object-space sheet-buffer} and emph{image-space sheet-buffer}. -
Image-space sheet-buffered splatting on the GPU
Grau Carrión, Sergi; Tost Pardell, Daniela (2007-03)
Report de recerca
Accés obertImage-Space Sheet-Buffered Splatting is a popular high quality volume-rendering technique specially suitable for zoomed views of the data. On the contrary to other splatting approaches, it processes the voxels in slabs ... -
Intelligent interactive volume classification
Grau Carrión, Sergi; Puig Puig, Anna; Escalera, Sergio; Salamó, Maria (2013)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper defines an intelligent and interactive framework to classify multiple regions of interest from the original data on demand, without requiring any preprocessing or previous segmentation. The proposed intelligent ... -
Interaction techniques in virtual environments
Moya Santos, Sergio; Grau Carrión, Sergi; Tost Pardell, Daniela (2013)
Report de recerca
Accés obertVirtual environments are used in very diverse applications: from leisure games to professional training and rehabilitation systems. In these applications, users interact with the elements of the environments through avatars ... -
Region-based illustrative visualization of multimodal datasets
Abellán Moreno, Pascual; Tost Pardell, Daniela; Grau Carrión, Sergi; Puig Puig, Anna (2013-06-01)
Article
Accés restringit per política de l'editorialWe present as novel method for the exploration of multiple overlapping volumes that provides flexibility to merge data in different ways in different regions. In each region, either one of the modalities is rendered alone ... -
