    • A Halfedge Refinement Rule for Parallel Catmull-Clark Subdivision 

      Dupuy, Jonathan; Vanhoey, Kenneth (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      We show that Catmull-Clark subdivision induces an invariant one-to-four refinement rule for halfedges that reduces to simple algebraic expressions. This has two important consequences. First, it allows to refine the halfedges ...

    • Hardware Adaptive High-Order Interpolation for Real-Time Graphics 

      Lin, Daqi; Seiler, Larry; Yuksel, Cem (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      Interpolation is a core operation that has widespread use in computer graphics. Though higher-order interpolation provides better quality, linear interpolation is often preferred due to its simplicity, performance, and ...

    • ReSTIR GI: Path Resampling for Real-Time Path Tracing 

      Ouyang, Yaobin; Liu, Shiqiu; Kettunen, Markus; Pharr, Matt; Pantaleoni, Jacopo (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      Even with the advent of hardware-accelerated ray tracing in modern GPUs, only a small number of rays can be traced at each pixel in real-time applications. This presents a significant challenge for path tracing, even when ...

    • Sampling from Quadric-Based CSG Surfaces 

      Trettner, Philip; Kobbelt, Leif (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      We present an efficient method to create samples directly on surfaces defined by constructive solid geometry (CSG) trees or graphs. The generated samples can be used for visualization or as an approximation to the actual ...
