High-quality particle-based volume rendering for large-scale unstructured volume datasets
Journal of Visualization - Tập 16 - Trang 153-162 - 2013
Naohisa Sakamoto, Naoya Maeda, Takuma Kawamura, Koji Koyamada
In this article, we propose a technique for improving the image quality of particle-based volume rendering (PBVR). A large-scale unstructured volume dataset often contains multiple sub-volumes, which cannot be ordered by visibility. PBVR can handle this type of volume dataset. Sampling misses often occur when the transfer function undergoes drastic changes, which can result in poor image quality. ...... hiện toàn bộ
CUDA-accelerated simulation of multiple scattering using decoupling approximation
Journal of Visualization - - 2011
Zheng Gong, Luis Diago, Ichiro Hagiwara
In this research a CUDA-accelerated simulation method of multiple scattering in dense participating media based on decoupling approximation is proposed. Simulation of multiple scattering is important, in that it visually illustrates how radiance transfers between gaseous particles. The existing radiance transfer equation has poor computational performance because of its complicated integral calcul...... hiện toàn bộ

Visualizing dynamic data with heat triangles
Journal of Visualization - Tập 25 - Trang 15-29 - 2021
Ya Ting Hu, Michael Burch, Huub van de Wetering
In this paper, an overview-based interactive visualization for temporally long dynamic data sequences is described. To reach this goal, each data object at a certain time point can be mapped to a number value based on a given property. Among others, a property is application-dependent and can be number of vertices, number of edges, average degree, density, number of self-loops, degree (maximum and...... hiện toàn bộ

Advanced surface oil flow visualization technique applied to complex transonic flows for the verification of viscous effects in CFD
Journal of Visualization - Tập 26 - Trang 131-141 - 2022
Alina Mielke, Daniel Klatt, Friedrich Leopold, Christian Mundt
An advanced multi-color surface oil flow technique is used to visualize the wall shear stress distributions on two different wind tunnel models in transonic as well as supersonic flow conditions reaching from Mach 0.9 to Mach 2.0. The results of the visualizations are superpositioned by numerically calculated wall shear stress distributions. Not only the shear stress directions are analyzed but in...... hiện toàn bộ
Theoretical formulation of streak failure conditions and numerical investigation to optimize the illumination code of particle streak velocimetry
Journal of Visualization - Tập 26 - Trang 1359-1374 - 2023
Yusaku Tsukamoto, Shumpei Funatani
In a typical coding method for particle streak velocimetry, the streak shape is divided into two dots and one line by controlling the illumination timing. In this study, several parameters were formulated to optimize the streak shape in a uniform flow using a theoretical approach. In contrast, for non-uniform flows, the formulation of optimal conditions does not provide a common criterion for all ...... hiện toàn bộ
Evaluation of the cross correlation method by using PIV standard images
Journal of Visualization - Tập 1 - Trang 87-94 - 1998
H. Hu, T. Saga, T. Kobayashi, K. Okamoto, N. Taniguchi
Effects of various parameters for PIV image acquiring and processing on the final velocity field is studied by using PIV standard images (Okamoto et al., 1997) to evaluate the cross correlation method. The studied parameters include the size of interrogation window, the size of search window, the number of tracer particles, the diameter of tracer particles, out-of-plane velocity and average image ...... hiện toàn bộ
