Left-Ventricle Global and Regional Functional Analysis from MDCT Images
(The Eurographics Association, 2021)Left-ventricle functional analysis is of paramount importance for the assessment of coronary artery disease. Non-invasive coronary artery imaging using multiple-detector computed tomography (MDCT) provides a wealth of data ... -
Linear-Time Dynamics of Characters with Stiff Joints
(The Eurographics Association, 2021)Characters, like other articulated objects and structures, are typically simulated using articulated dynamics algorithms. There are efficient linear-time algorithms for the simulation of open-chain articulated bodies, but ... -
Mobile Computational Photography: Exposure Fusion on the Nokia N900
(The Eurographics Association, 2021)This paper explores the Nokia N900 platform as a versatile playground for mobile computational photography. We present the implementation of a simple yet practical application to acquire high quality tone mapped HDR images, ... -
A Moving Least Squares Method for Implant Model Deformation in Computer Aided Orthopedic Surgery for Fractures of Lower Extremities
(The Eurographics Association, 2021)Preoperative planning is an essential step before performing any surgical procedure. Computer Aided Orthopedic Surgery (CAOS) systems are extensively used for the planning of surgeries for fractures of lower extremities. ... -
Neural Data Exploration with Force Feedback
(The Eurographics Association, 2021)The behavior of the brain depends to a large extend on its neural structure. Therefore, understanding this neural topology is a high-priority research line for neurobiologists. Due to complexity of the brain's neural ... -
Non-Uniform Spherical Light Fields
(The Eurographics Association, 2021)The study of the light field, as a function defining the radiance along the different viewing directions of a scene, started more than a decade ago and is still ongoing due to its interesting applications. Among the different ... -
Parallel Collision Detection Oriented to Distributed Memory Architectures for High-Resolution Meshes
(The Eurographics Association, 2021)Higher resolution meshes should be used in graphics applications to make them as realistic as they can. However, they imply a high computational. Several approaches have been built to solve collision detection, although ... -
Procedural Modeling of Suspension Bridges
(The Eurographics Association, 2021)In this paper we introduce a method for designing a class of engineering structures, namely suspension bridges. These bridges are ubiquitous in the industrialized countries, often appearing in known city landscapes, yet ... -
Procedural Modelling of Destructible Materials
(The Eurographics Association, 2021)Traditional content creation for computer games is a costly process. In particular, current techniques for authoring destructible behaviour are often limited to a single object basis. In this paper, we build on previous ... -

Real-Time Modelling and Rendering of Sprayed Concrete
(The Eurographics Association, 2021)This paper presents a new real-time method to model and render how sprayed concrete is spread on a surface. The method not only models and renders deposits sprayed from any angle, any distance and with any concrete flow, ... -
Robust Method for Estimating Normals on Point Clouds Using Adaptive Neighborhood Size
(The Eurographics Association, 2021)Normal estimation on sampled curves or surfaces is a basic step of many algorithms in computer graphics, computer vision, and especially in recognition and reconstruction of three dimensional objects. This paper presents ... -
A Simple Surface Tracking Method for Physically-Based 3D Water Simulations
(The Eurographics Association, 2021)Water simulation, and more generically fluid simulation, is an important research topic in computer graphics. In 3D Eulerian Navier-Stokes-based water simulations, surface tracking and rendering are two delicate problems. ... -
Volume-Surface Collision Detection
(The Eurographics Association, 2021)The presence or not of collisions between objects is usually required to study the interaction between them, increasing the realism in virtual environments. Collision detection between polygonal objects has been widely ...
