    • 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, ...

    • Robust Method for Estimating Normals on Point Clouds Using Adaptive Neighborhood Size 

      Leal, E.A.; Leal, N.E. (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 

      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. ...

    • Volume-Surface Collision Detection 

      Ortegano, J.; Navarro, H.; Carmona, R. (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 ...
