Analysis of Cache Behavior and Performance of Different BVH Memory Layouts for Tracing Incoherent Rays
(The Eurographics Association, 2013)
With CPUs moving towards many-core architectures and GPUs becoming more general purpose architectures, path tracing can now be well parallelized on commodity hardware. While parallelization is trivial in theory, properties ...
Iso Photographic Rendering
(The Eurographics Association, 2018)
In the field of computer graphics, the simulation of the visual appearance of materials requires an accurate computation of the light transport equation. Consequently, material models need to take into account various ...
Reduced Precision for Hardware Ray Tracing in GPUs
(The Eurographics Association, 2014)
We propose a high performance, GPU integrated, hardware ray tracing system. We present and make use of a new analysis of ray traversal in axis aligned bounding volume hierarchies. This analysis enables compact traversal ...
Bandwidth-Efficient BVH Layout for Incremental Hardware Traversal
(The Eurographics Association, 2016)
The memory footprint of bounding volume hierarchies (BVHs) can be significantly reduced using incremental encoding, which enables the coarse quantization of bounding volumes. However, this compression alone does not ...
An Energy and Bandwidth Efficient Ray Tracing Architecture
(ACM, 2013)
We propose two hardware mechanisms to decrease energy consumption on massively parallel graphics processors for ray tracing while keeping performance high. First, we use a streaming data model and configure part of the L2 ...
SGRT: A Mobile GPU Architecture for Real-Time Ray Tracing
(ACM, 2013)
Recently, with the increasing demand for photorealistic graphics and the rapid advances in desktop CPUs/GPUs, real-time ray tracing has attracted considerable attention. Unfortunately, ray tracing in the current mobile ...
Megakernels Considered Harmful: Wavefront Path Tracing on GPUs
(ACM, 2013)
When programming for GPUs, simply porting a large CPU program into an equally large GPU kernel is generally not a good approach. Due to SIMT execution model on GPUs, divergence in control flow carries substantial performance ...
