Ítem Volume Ray Casting in WebGL(InTech, 2012-03-01) Congote, John; Kabongo, Luis; Moreno, Aitor; Segura, Alvaro; Ruiz OE; Posada, Jorge; Beristain, Andoni; Universidad EAFIT. Departamento de Ingeniería Mecánica; Laboratorio CAD/CAM/CAEReal-time 3D computer graphics systems usually handle surface description models (i.e. BRep representations) and use surface rendering techniques for visualization. Common 3D model formats such as VRML, X3D, COLLADA, U3D (some intended for the Web)Ítem Volume Ray Casting in WebGL(Intech Open, 2012) Congote, John; Kabongo, Luis; Moreno, Aitor; Segura, Alvaro; Beristain, Andoni; Posada, Jorge; Ruíz, Oscar; Universidad EAFIT. Departamento de Ingeniería Mecánica; Laboratorio CAD/CAM/CAEÍtem Volume Visual Attention Maps (VVAM) in Ray-Casting Rendering(IOS Press, 2012) Beristain, Andoni; Congote, John; Ruíz, Óscar; Universidad EAFIT. Departamento de Ingeniería Mecánica; Laboratorio CAD/CAM/CAEThis paper presents an extension visual attention maps for volume data visualization, where eye fixation points become rays in the 3D space, and the visual attention map becomes a volume -- This Volume Visual Attention Map (VVAM) is used to interactively enhance a ray-casting based direct volume rendering DVR visualization -- The practical application of this idea into the biomedical image visualization field is explored for interactive visualization
