• Data Parallel Path Tracing with Object Hierarchies 

  Wald, Ingo; Parker, Steven G (ACM Association for Computing Machinery, 2022)

  We propose a new approach to rendering production-style content with full path tracing in a data-distributed fashion-that is, with multiple collaborating nodes and/or GPUs that each store only part of the model. In particular, ...

• PLOC++ : Parallel Locally-Ordered Clustering for Bounding Volume Hierarchy Construction Revisited 

  Benthin, Carsten; Drabinski, Radoslaw; Tessari, Lorenzo; Dittebrandt, Addis (ACM Association for Computing Machinery, 2022)

  We propose a novel version of the GPU-oriented massively parallel locally-ordered clustering (PLOC) algorithm for constructing bounding volume hierarchies (BVHs). Our method focuses on removing the weaknesses of the original ...

• Better Fixed-Point Filtering with Averaging Trees 

  Adams, Andrew; Sharlet, Dillon (ACM Association for Computing Machinery, 2022)

  Production imaging pipelines commonly operate using fixed-point arithmetic, and within these pipelines a core primitive is convolution by small filters - taking convex combinations of fixed-point values in order to ...

• Htex: Per-Halfedge Texturing for Arbitrary Mesh Topologies 

  Barbier, Wilhem; Dupuy, Jonathan (ACM Association for Computing Machinery, 2022)

  We introduce per-halfedge texturing (Htex) a GPU-friendly method for texturing arbitrary polygon-meshes without an explicit parameterization. Htex builds upon the insight that halfedges encode an intrinsic triangulation ...

• A Data-Driven Paradigm for Precomputed Radiance Transfer 

  Belcour, Laurent; Deliot, Thomas; Barbier, Wilhem; Soler, Cyril (ACM Association for Computing Machinery, 2022)

  In this work, we explore a change of paradigm to build Precomputed Radiance Transfer (PRT) methods in a data-driven way. This paradigm shift allows us to alleviate the difficulties of building traditional PRT methods such ...

• High-Performance Polynomial Root Finding for Graphics 

  Yuksel, Cem (ACM Association for Computing Machinery, 2022)

  We present a computationally-efficient and numerically-robust algorithm for finding real roots of polynomials. It begins with determining the intervals where the given polynomial is monotonic. Then, it performs a robust ...

• Ray/Ribbon Intersections 

  Reshetov, Alexander (ACM Association for Computing Machinery, 2022)

  We present a new ray tracing primitive-a curved ribbon, which is embedded inside a ruled surface. We describe two such surfaces. Ribbons inside doubly ruled bilinear patches can be intersected by solving a quadratic equation. ...

• Supporting Unified Shader Specialization by Co-opting C++ Features 

  Seitz, Kerry A.; Foley, Theresa; Porumbescu, Serban D.; Owens, John D. (ACM Association for Computing Machinery, 2022)

  Modern unified programming models (such as CUDA and SYCL) that combine host (CPU) code and GPU code into the same programming language, same file, and same lexical scope lack adequate support for GPU code specialization, ...

• Software Rasterization of 2 Billion Points in Real Time 

  Schütz, Markus; Kerbl, Bernhard; Wimmer, Michael (ACM Association for Computing Machinery, 2022)

  The accelerated collection of detailed real-world 3D data in the form of ever-larger point clouds is sparking a demand for novel visualization techniques that are capable of rendering billions of point primitives in ...

• Virtual Blue Noise Lighting 

  Li, Tianyu; Wang, Wenyou; Lin, Daqi; Yuksel, Cem (ACM Association for Computing Machinery, 2022)

  We introduce virtual blue noise lighting, a rendering pipeline for estimating indirect illumination with a blue noise distribution of virtual lights. Our pipeline is designed for virtual lights with non-uniform emission ...

• Spatiotemporal Variance-Guided Filtering for Motion Blur 

  Oberberger, Max; Chajdas, Matthäus G.; Westermann, Rüdiger (ACM Association for Computing Machinery, 2022)

  Adding motion blur to a scene can help to convey the feeling of speed even at low frame rates. Monte Carlo ray tracing can compute accurate motion blur, but requires a large number of samples per pixel to converge. In ...

• Temporally Stable Real-Time Joint Neural Denoising and Supersampling 

  Thomas, Manu Mathew; Liktor, Gabor; Peters, Christoph; Kim, Sungye; Vaidyanathan, Karthik; Forbes, Angus G. (ACM Association for Computing Machinery, 2022)

  Recent advances in ray tracing hardware bring real-time path tracing into reach, and ray traced soft shadows, glossy reflections, and diffuse global illumination are now common features in games. Nonetheless, ray budgets ...

• OmniTiles - A User-Customizable Display Using An Omni-Directional Camera Projector System 

  Hoffard, Jana; Miyafuji, Shio; Pardomuan, Jefferson; Sato, Toshiki; Koike, Hideki (The Eurographics Association, 2022)

  We present OmniTiles, a manually changeable interface that enables the user to customize their own display. This is achieved by using tiles in basic shapes that are clipped together via magnets. The created structures are ...

• Characteristics of Background Color Shifts Caused by Optical See-Through Head-Mounted Displays 

  Hirobe, Daichi; Uranishi, Yuki; Orlosky, Jason; Shirai, Shizuka; Ratsamee, Photchara; Takemura, Haruo (The Eurographics Association, 2022)

  Optical see-through head-mounted displays (OST-HMDs) have been increasingly used in many applications as Augmented Reality (AR) support devices. However, problems still exist that prevent their use as general-purpose ...

• A Rendering Method of Microdisplay Image to Expand Pupil Movable Region without Artifacts for Lenslet Array Near-Eye Displays 

  Ye, Bi; Fujimoto, Yuichiro; Sawabe, Taishi; Kanbara, Masayuki; Lugtenberg, Geert; Kato, Hirokazu (The Eurographics Association, 2022)

  Near-eye displays (NEDs) with lenslet array (LA) are a technological advancement that generates a virtual image in the observer's field of view (FOV). Although this technology is useful for designing lightweight NEDs, ...

• Manipulating the Sense of Embodiment in Virtual Reality: a Study of the Interactions Between the Senses of Agency, Self-location and Ownership 

  Guy, Martin; Jeunet-Kelway, Camille; Moreau, Guillaume; Normand, Jean-Marie (The Eurographics Association, 2022)

  In Virtual Reality (VR), the Sense of Embodiment (SoE) corresponds to the feeling of controlling and owning a virtual body, usually referred to as an avatar. The SoE is generally divided into three components: the Sense ...

• Could you Relax in an Artistic Co-creative Virtual Reality Experience?
