Progressive CPU Volume Rendering with Sample Accumulation
(The Eurographics Association, 2017)
We present a new method for progressive volume rendering by accumulating object-space samples over successively rendered frames. Existing methods for progressive refinement either use image space methods or average pixels ...
Interactive Exploration of Dissipation Element Geometry
(The Eurographics Association, 2017)
Dissipation elements (DE) define a geometrical structure for the analysis of small-scale turbulence. Existing analyses based on DEs focus on a statistical treatment of large populations of DEs. In this paper, we propose a ...
Direct Raytracing of Particle-based Fluid Surfaces Using Anisotropic Kernels
(The Eurographics Association, 2018)
Particle-based simulation models have assumed a significant role in the numerical computation of high-fidelity transient flow and continuum mechanical problems. However, direct visualization of surfaces from particle data ...
VisIt-OSPRay: Toward an Exascale Volume Visualization System
(The Eurographics Association, 2018)
Large-scale simulations can easily produce data in excess of what can be efficiently visualized using production visualization software, making it challenging for scientists to gain insights from the results of these ...
Robust Iterative Find-Next-Hit Ray Traversal
(The Eurographics Association, 2018)
We present two different methods for improving the performance and robustness of ray tracing algorithms that require iterating through multiple successive intersections along the same ray. Our methods do so without ever ...
SIMD Parallel Ray Tracing of Homogeneous Polyhedral Grids
(The Eurographics Association, 2015)
Efficient visualization of unstructured data is vital for domain scientists, yet is often impeded by techniques which rely on intermediate representations that consume time and memory, require resampling data, or inefficient ...
