High-Quality Rendering of Glyphs Using Hardware-Accelerated Ray Tracing
(The Eurographics Association, 2020)
Glyph rendering is an important scientific visualization technique for 3D, time-varying simulation data and for higherdimensional data in general. Though conceptually simple, there are several different challenges when ...
Using Hardware Ray Transforms to Accelerate Ray/Primitive Intersections for Long, Thin Primitive Types
(ACM, 2020)
With the recent addition of hardware ray tracing capabilities, GPUs have become incredibly efficient at ray tracing both triangular geometry, and instances thereof. However, the bounding volume hierarchies that current ray ...
Compressed-Leaf Bounding Volume Hierarchies
(ACM, 2018)
We propose and evaluate what we call Compressed-Leaf Bounding Volume Hierarchies (CLBVH), which strike a balance between compressed and non-compressed BVH layouts. Our CLBVH layout introduces dedicated compressed multi-leaf ...
RTX Beyond Ray Tracing: Exploring the Use of Hardware Ray Tracing Cores for Tet-Mesh Point Location
(The Eurographics Association, 2019)
We explore a first proof-of-concept example of creatively using the Turing generation's hardware ray tracing cores to solve a problem other than classical ray tracing, specifically, point location in unstructured tetrahedral ...
Finding Efficient Spatial Distributions for Massively Instanced 3-d Models
(The Eurographics Association, 2020)
Instancing is commonly used to reduce the memory footprint of massive 3-d models. Nevertheless, large production assets often do not fit into the memory allocated to a single rendering node or into the video memory of a ...
Faster RTX-Accelerated Empty Space Skipping using Triangulated Active Region Boundary Geometry
(The Eurographics Association, 2021)
We describe a technique for GPU and RTX accelerated space skipping of structured volumes that improves on prior work by replacing clustered proxy boxes with a GPU-extracted triangle mesh that bounds the active regions. ...
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, ...
Design and Evaluation of a GPU Streaming Framework for Visualizing Time-Varying AMR Data
(The Eurographics Association, 2022)
We describe a systematic approach for rendering time-varying simulation data produced by exa-scale simulations, using GPU workstations. The data sets we focus on use adaptive mesh refinement (AMR) to overcome memory bandwidth ...
