GPU Improvements on the Sorting and Projection of Tetrahedral Meshes for Direct Volume Rendering
Direct Volume Rendering is one of the most popular visualization techniques. Although approaches such as ray-casting or slicing are fast and well-implemented on graphics hardware for regular and irregular grids, cell projection techniques are still time-consuming for large tetrahedral meshes. We propose improvements to the pipeline of cell projection techniques based on the SXMPVO [4] and the P...
متن کاملFast Ray Traversal of Tetrahedral and Hexahedral Meshes for Direct Volume Rendering
The importance of high-performance rendering of unstructured or curvilinear data sets has increased significantly, mainly due to its use in scientific simulations such as computational fluid dynamics and finite element computations. However, the unstructured nature of these data sets lead to rather slow implementations for ray tracing. The approaches discussed in this paper are fast and scalabl...
متن کاملDirect volume rendering of unstructured grids
This paper investigates three categories of algorithms for direct volume rendering of unstructured grids, which are image-space, object-space, and hybrid methods. We propose three new algorithms. Cell Projection algorithm, which falls into object-space category, is capable of rendering non-convex meshes through a simple yet efficient sorting schema that exploits both image and object space cohe...
متن کاملIncremental Slicing Revisited: Accelerated Volume Rendering Of Unstructured Meshes
We accelerate the incremental slicing method for near interactive volume rendering of unstructured grids with conventional polygon rendering hardware support. Our method uses less memory compared to the method of Yagel et al. [25], with significant improvements in rendering time. Using our method, a rendering performance gain of at least 400% was achieved for some datasets, e.g., the Blunt fin ...
متن کاملVolume Rendering of Time-Varying Scalar Fields on Unstructured Meshes
Volume Rendering of time-varying datasets is essential in several scientific applications. Due to the enormous amount of data involved, in datasets with static sampling regions it is common to consider only time-varying scalar fields (TVSFs). The use of Vector Quantization (VQ) to compress scalar fields has been shown to be quite effective when combined with texture-based volume rendering algor...
