There is a strong need for acquisition of high quality volume data sets, with the vision of visualizing organs, engines or other materials for variant fields. Visualized computer model provides interactive investigation and improves understanding of details of substances. Since the quality of volume data which is acquired by CT and MRI devices is impacted by noisy, partial effect and bias seriously,...
Visualizing segmented heart and integral chest clearly and precisely would be beneficial for pathology research, presurgical planning and clinical approach. In this paper we investigated the visualization of the segmented heart obtained by cryosection images from Visible Human Project. In addition, the result also visualizes the integral chest to represent the spatial characteristics of the heart...
Instead of simple point or area lights for illuminating human face in most rendering methods, we aim to render the appearance of human face influenced by surrounding environment lighting in some real scenes. In this paper, we accurately approximate the specular reflection by using the Kelemen/Szirmay-Kalos reflectance model and ten varying specular parameters over the whole face. Also, subsurface...
In this study, we present a framework to simulate multi-scale wave propagation of ischemia which leverages the high-performance computing capacity of Graphic Processing Units (GPU). To cope with the no-flux boundary condition and address the branch deficiency, a phase-field method is employed. An on-the-fly visualization method of two dimensional simulation results is proposed. A fusion volume visualization...
The layered structure of human heart is a challenging task for visualization. Conventional visualization method can hardly be used to provide satisfied rendering results due to the complex anatomical structure of human heart. In addition, it is very hard to find a balance between rendering the inner structure and the silhouettes of the heart. In this work we adopt the context-preserving volume rendering...
Real-time interactive visualization plays an important role in the analysis of 3D cardiac imaging data and the assessment of electrophysiological simulation result. Recently, the graphics programmable processor unit (GPU), an increasingly convincing acceleration approach, has been widely adopted in various graphics, visualization, and scientific computing applications. In this paper, we present a...
