Direct 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 کاملVolume Rendering for Curvilinear and Unstructured Grids
We discuss two volume rendering methods developed at Lawrence Livermore National Laboratory. The first, cell projection, renders the polygons in the projection of each cell. It requires a global visibility sort in order to composite the cells in back to front order, and we discuss several different algorithms for this sort. The second method uses regularly spaced slice planes perpendicular to t...
متن کاملA Survey of GPU-Based Volume Rendering of Unstructured Grids
Real-time rendering of large unstructured meshes is a major research goal in the scientific visualization community. While, for regular grids, texture-based techniques are well-suited for current Graphics Processing Units (GPUs), the steps necessary for rendering unstructured meshes are not so easily mapped to current hardware. This paper reviews volume rendering algorithms and techniques for u...
متن کاملHardware Architecture for Voxelization-based Volume Rendering of Unstructured Grids
Interactive volume visualization of unstruc.tured grid data is a much sought after, but as yet elusive, goal in many scientifie visualization applieations. We present an architecture that ean possibly bring this goal within reaeh. In this architecture we eombine the recently identified method of using texture mapping for volume rendering[5, 2] with anti-aliased voxelization. We show how the pro...
متن کاملImage-Space Acceleration for Direct Volume Rendering of Unstructured Grids using Joint Bilateral Upsampling
We describe a new image-space acceleration technique that allows real-time direct volume rendering of large unstructured volumes. Our algorithm operates as a simple post-process and can be used to improve the performance of any existing volume renderer that is sensitive to image size. A joint bilateral upsampling filter allows images to be rendered efficiently at a fraction of their original si...
