      Real-time crowd simulation for virtual environment applications requires not only navigation and locomotion in large environments while avoiding obstacles and agents, but also rendering high quality 3D fully articulated ...
    • A survey of real-time crowd rendering 

      Beacco Porres, Alejandro; Pelechano Gómez, Núria; Andújar Gran, Carlos Antonio (2016-12)
      Article
      Open Access
      In this survey we review, classify and compare existing approaches for real-time crowd rendering. We first overview character animation techniques, as they are highly tied to crowd rendering performance, and then we analyze ...

      Spanlang, Bernhard; Pelechano Gómez, Núria; Beacco Porres, Alejandro (2010)
      Conference lecture
      Restricted access - publisher's policy
      This poster presents an efficient Animation Planning Mediator (APM) designed to animate virtual characters in real time for crowd simulation. The APM selects the most appropriate animation clip available for each character ...
    • Efficient rendering of animated characters through optimized per-joint impostors 

      Beacco Porres, Alejandro; Andújar Gran, Carlos Antonio; Pelechano Gómez, Núria; Spanlang, Bernhard (2012-02)
      Article
      Restricted access - publisher's policy
      In this paper, we present a new impostor-based representation for 3D animated characters supporting real-time rendering of thousands of agents. We maximize rendering performance by using a collection of pre-computed ...
    • Exploiting the potential of image based crowd rendering 

      Izquierdo, Maria; Beacco Porres, Alejandro; Pelechano Gómez, Núria; Andújar Gran, Carlos Antonio (European Association for Computer Graphics (Eurographics), 2015)
      Conference lecture
      Restricted access - publisher's policy
      Per-joint impostors have been used to achieve high performance when rendering thousands of agents, while still allowing us to blend animation. This provides interactively animated crowds and reduces the memory footprint ...
    • Footstep parameterized motion blending using barycentric coordinates 

      Beacco Porres, Alejandro; Pelechano Gómez, Núria; Kapadia, Mubbasir; Badler, Norman (2015-04-01)
      Article
      Open Access
      This paper presents a real-time animation system for fully embodied virtual humans that satisfies accurate foot placement constraints for different human walking and running styles. Our method offers a fine balance between ...
    • Impostor-based crowd rendering 

      Beacco Porres, Alejandro; Pelechano Gómez, Núria; Andújar Gran, Carlos Antonio (CRC Press, 2016-09-27)
      Part of book or chapter of book
      Restricted access - publisher's policy
      Real-time rendering of detailed animated characters in crowd simulations is still a challenging problem in computer graphics. State-of-the-art approaches can render up to several thousand agents by consuming most of the ...
