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, ...
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. ...
ERAS - An Ontology-Based Tool for Expeditious Reconstruction of Virtual Cultural Heritage Sites
(The Eurographics Association, 2021)
Nos últimos anos, vários investigadores têm proposto métodos semiautomáticos para a geração expedita de modelos virtuais de edifícios e até cidades, em alguns casos direcionados à reconstrução do património cultural. No ...
GPU Collision Detection in Conformal Geometric Space
(The Eurographics Association, 2021)
We derive a conformal algebra treatment unifying all types of collisions among points, vectors, areas (defined by bivectors and trivectors) and 3D solid objects (defined by trivectors and quadvectors), based in a reformulation ...
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. ...
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 ...
Pair Correlation Functions with Free-Form Boundaries for Distribution Inpainting and Decomposition
(The Eurographics Association, 2020)
Pair Correlation Functions (PCF) have been recently spreading as a reliable representation for distributions, enabling the efficient synthesis of point-sets, vector textures and object placement from examples. In this work ...
Poisson Surface Reconstruction with Envelope Constraints
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Reconstructing surfaces from scanned 3D points has been an important research area for several decades. One common approach that has proven efficient and robust to noise is implicit surface reconstruction, i.e. fitting to ...
