      Simultaneous multi-impact simulation is a challenging problem that frequently arises in physically-based modeling of rigid bodies. There are several physical criteria that should be satisfied for rigid body collision ...
    • Virtual Spherical Gaussian Lights for Real-time Glossy Indirect Illumination 

      Tokuyoshi, Yusuke (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Virtual point lights (VPLs) are well established for real-time global illumination. However, this method suffers from spiky artifacts and flickering caused by singularities of VPLs, highly glossy materials, high-frequency ...

      LEGO, a popular brick-based toy construction system, provides an affordable and convenient way of fabricating geometric shapes. However, building arbitrary shapes using LEGO bricks with restrictive colors and sizes is not ...
    • Towards Automatic Band-Limited Procedural Shaders 

      Dorn, Jonathan; Barnes, Connelly; Lawrence, Jason; Weimer, Westley (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Procedural shaders are a vital part of modern rendering systems. Despite their prevalence, however, procedural shaders remain sensitive to aliasing any time they are sampled at a rate below the Nyquist limit. Antialiasing ...
