A Coherent Projection Approach For Direct Volume Rendering

A Coherent Projection Approach For Direct Volume Rendering written by Jane Wilhelms and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1990 with Computer graphics categories.

It projects each volume cell as one to seven polygons, calculates color and opacity for each vertex, and interpolates across the polygons to render the cell. In its fastest form, the interpolation is linear in color and opacity and amounts to Gouraud shaded polygon scan conversion. It is limited to rectilinear sample volumes rendered without perspective."

One approach is to ray-cast such volumes directly. An alternative approach is to interpolate the sample volumes to a rectilinear grid, and use this regular volume for rendering. Advantages and disadvantages of the two approaches in terms of speed and image quality are explored."

Interactive Direct Volume Rendering Of Curvilinear And Unstructured Data

Interactive Direct Volume Rendering Of Curvilinear And Unstructured Data written by Peter Lawrence Williams and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1993 with Boundary value problems categories.

The effects of cyclically obstructing polyhedra are discussed, and methods for their elimination are described, including the use of the Delaunay triangulation. Methods for converting nonconvex meshes into convex meshes are described. A suite of splatting approximations are presented, which along with other more accurate methods discussed, form a hierarchy of rendering methods that tradeoff image accuracy/quality and generation time. Parallel volume rendering algorithms that include visibility ordering for both convex and nonconvex irregular meshes are investigated and results are given for several versions of parallel algorithms. A performance analysis of one of these algorithms on a high performance MIMD 3D graphics workstation is presented."

The work in this thesis was motivated by the demands of an ongoing visualization project in four-dimensional cardiac visualization. We present solutions to some key problems in ensuring accuracy and in producing algorithms that can scale to handle large datasets. Although the theoretical work in this thesis applies to arbitrary data topologies, our implementations have assumed that the data is defined by sample points on a regular rectilinear grid.
