    • GPU Collision Detection in Conformal Geometric Space 

      Roa, Eduardo; Theoktisto, Víctor; Fairén, Marta; Navazo, Isabel (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 

      Ramírez, Esmitt; Coto, Ernesto (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 

      Patow, Gustavo (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 ...

    • Real-Time Modelling and Rendering of Sprayed Concrete 

      Vélez, G.; Matey, L.; Amundarain, A.; Ordás, F.; Marín, J.A. (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 

      Amador, G.; Gomes, A. (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. ...
