Data Parallel Path Tracing with Object Hierarchies
(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
(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
(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
(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
(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
(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
(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
(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
(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
(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
(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
(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 ...
