Visualization of dynamic active devices via adaptive undersampled projection imaging

Adaptive Projection Operators in Multiresolution Scientific Visualization

Recently, multiresolution visualization methods have become an indispensable ingredient of real-time interactive postprocessing. The enormous databases, typically coming along with some hierarchical structure, are locally resolved on different levels of detail to achieve a significant savings of CPU and rendering time. Here, the method of adaptive projection and the corresponding operators on d...

Undersampled projection reconstruction applied to MR angiography.

Undersampled projection reconstruction (PR) is investigated as an alternative method for MRA (MR angiography). In conventional 3D Fourier transform (FT) MRA, resolution in the phase-encoding direction is proportional to acquisition time. Since the PR resolution in all directions is determined by the readout resolution, independent of the number of projections (Np), high resolution can be genera...

Adaptive Visualization of Dynamic Unstructured Meshes

Visualization of time-varying volume data is essential for understanding the results of scientific simulations. Interactive exploration of these datasets is a challenging problem since the data is often unstructured and may contain many time and domain field instances. We propose an adaptive framework for interactively volume rendering large dynamic unstructured meshes on a commodity PC by effi...

Visualization of dynamic adaptive resolution scientific data

Interactive visualization of very large data sets remains a challenging problem to the visualization community. One promising solution involves using adaptive resolution representations of the data. In this model, important regions of data are identified using reconstructive error analysis and are shown in higher detail. During the visualization, regions with higher error are rendered with high...
