Dynamic view-dependent visualization of unstructured tetrahedral volumetric meshes

Dynamic view-dependent visualization of unstructured tetrahedral volumetric meshes

Visualization of large volumetric datasets has always been an important problem. Due to the high computational requirements of volume-rendering techniques, achieving interactive rates is a real challenge. We present a selective refinement scheme that dynamically refines the mesh according to the camera parameters. This scheme automatically determines the impact of different parts of the mesh on...

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...

Volumetric Real-Time Particle-Based Representation of Large Unstructured Tetrahedral Polygon Meshes

In this paper we propose a particle-based volume rendering approach for unstructured, three-dimensional, tetrahedral polygon meshes. We stochastically generate millions of particles per second and project them on the screen in real-time. In contrast to previous rendering techniques of tetrahedral volume meshes, our method does not need a prior depth sorting of geometry. Instead, the rendered im...

Recursive Tetrahedral Meshes for Scientific Visualization

The advent of high-performance computing has completely transformed the nature of most scientific and engineering disciplines, making the study of complex problems from experimental and theoretical disciplines computationally feasible. All science and engineering disciplines are facing the same problem: how to archive, transmit, visualize, and explore the massive data sets resulting from modern...
