PrimeSense Sensors as a Low-cost Method for Motion Capture on Clinical Tests
(The Eurographics Association, 2012)Virtual Reality (VR) is the computer recreation of simulated environments that create on the user a sense of physical presence. VR provides the advantages of being highly flexible and controllable, allowing experts to ... -
Design of a Scalable System for the Sensorization of Virtual TV Sets with Live Broadcast
(The Eurographics Association, 2012)The sensorization of virtual tv sets using motion capture systems allows the automation of many of the processes implied in the live broadcast of a tv show. It facilitates the tasks of both the actor (allowing him to ... -
A Procedural Modeling System for the Creation of Huge Models
(The Eurographics Association, 2012)This paper presents a new general purpose procedural geometrical modeling system. It is focused on providing flexibility, modularity and scalability. Furthermore, it is taylored to manage huge geometric models, with millions ... -
Design of an Information System for Cultural Heritage
(The Eurographics Association, 2012)Usually the information that must be managed by archaeologist for any cultural heritage artefact is very heterogeneous. Due to its spatial nature this information cannot be easily represented with conventional data management ... -
Analysis of Coded Apertures for Defocus Deblurring of HDR Images
(The Eurographics Association, 2012)In recent years, research on computational photography has reached important advances in the field of coded apertures for defocus deblurring. These advances are known to perform well for low dynamic range images (LDR), but ... -
Interactive Generation of (Paleontological) Scientific Illustrations from 3D-models
(The Eurographics Association, 2012)Scientific illustrations play an important role in the paleontological domain and are complex illustrations that are manually drawn. The artist creates illustrations that feature common expressive painting techniques: ... -
Generating Coherent Ray Directions in Path Tracing
(The Eurographics Association, 2012)The quality of the images produced by a global illumination rendering engine is highly connected to the number of paths that are randomly generated from the camera to the light sources. Graphics Processing Units (GPUs) ... -
Differential Ray Marching
(The Eurographics Association, 2012)Several participating media rendering algorithms are based on ray marching: they integrate the variations of radiance along the volume covered by the participating media by splitting the path of light into segments and ... -
Visual Language Generalization for Procedural Modeling of Buildings
(The Eurographics Association, 2012)Procedural modeling has become the accepted standard for the creation of detailed large scenes, in particular urban landscapes. With the introduction of visual languages there has been a huge leap forward in terms of ... -
Bringing Direct Local Control to Interactive Visual Editing of Procedural Buildings
(The Eurographics Association, 2012)This paper presents a new system to add direct and persistent local control to the visual editing of rules for procedural buildings, avoiding a combinatorial explosion of grammar rules. In this paper we follow the ideas ... -
Locating Companies in 3D Urban Environments on the Internet
(The Eurographics Association, 2012)3D visualization is being incorporated in a lot of fields, including Geographic Information Systems (GIS). In addition, the Internet is the most popular method to find information, due to its accessibility. For this reason, ... -
Ventricular Puncture Trainer
(The Eurographics Association, 2012)The learning process in neurosurgery is a large and difficult task based on experimentation, being ventriculostomy not an exception. We have developed a virtual reality system to help training novel surgeons on this kind ... -
An Application to Interact with 3D Models Reconstructed from Medical Images
(The Eurographics Association, 2012)Although the reconstruction of 3D models from medical images is not an easy task, there are many algorithms to perform it. However, the reconstructed models are usually large, have a lot of outliers and have not a correct ... -
A GPU Based Method for the Automatic Generation of Near-Optimal Navigation Meshes
(The Eurographics Association, 2012)In this paper we present a novel, robust and efficient GPU based technique to automatically generate a Navigation Mesh for complex 3D scenes. Our method consists of two steps: firstly, starting with a 3D scene representing ... -
High Resolution Medical 3D Data Sets on Mobile Devices and WebGL
(The Eurographics Association, 2012)Nowadays, mobile devices and the web are being used to deliver 3D graphics to mass users. However, applications such as visualization of high resolution medical models are still impossible to handle in such platforms due ... -
Uncertainty Visualization of Brain Fibers
(The Eurographics Association, 2012)Diffuse Tensor Imaging (DTI) is an acquisition method based on Magnetic Resonance (MR) that provides information on the white matter fiber pathways in the living human brain. Such knowledge is crucial for understanding the ... -
More Stable SPH-based Fluid Simulation
(The Eurographics Association, 2012)The simulation of fluid is a field largely discussed, from the viewpoint of engineering, in the so-called computational fluid dynamics (CFD). A problem that occurs repeatedly in the literature of CFD is the stability of ... -
A New Approach to Explore Integral Field Spectroscopy Data
(The Eurographics Association, 2012)Integral field spectroscopy (IFS) is a technique that is widely used in astronomy. It gives simultaneously the spectra of each spatial sampling element of a given field, generating a large amount of information that is ...
