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 ...
On Quality Metrics of Bounding Volume Hierarchies
(ACM, 2013)
The surface area heuristic (SAH) is widely used as a predictor for ray tracing performance, and as a heuristic to guide the construction of spatial acceleration structures. We investigate how well SAH actually predicts ray ...
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 ...
Geometry Presorting for Implicit Object Space Partitioning
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present a new data structure for object space partitioning that can be represented completely implicitly. The bounds of each node in the tree structure are recreated at run-time from the scene objects contained therein. ...
Visualization of Particle-based Data with Transparency and Ambient Occlusion
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Particle-based simulation techniques, like the discrete element method or molecular dynamics, are widely used in many research fields. In real-time explorative visualization it is common to render the resulting data using ...
Polynomial Optics: A Construction Kit for Efficient Ray-Tracing of Lens Systems
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Simulation of light transport through lens systems plays an important role in graphics. While basic imaging properties can be conveniently derived from linear models (like ABCD matrices), these approximations fail to ...
Vessel Visualization using Curvicircular Feature Aggregation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Radiological investigations are common medical practice for the diagnosis of peripheral vascular diseases. Existing visualization methods such as Curved Planar Reformation (CPR) depict calcifications on vessel walls to ...
Hybrid Remote Visualization in Immersive Virtual Environments with Vistle
(The Eurographics Association, 2019)
Because of the spatial separation of high performance compute resources and immersive visualization systems, their combined use requires remote visualization. Remote rendering incurs increased latency from user interaction ...
