New Method for Opacity Correction in Oversampled Volume Ray Casting
نویسندگان
چکیده
A new opacity correction approach for oversampled volume ray casting is introduced. While the only existing opacity correction method in the literature is based on the assumption of dataset homogeneity, the new opacity correction method introduced in this paper is a faster, generalized voxel-by-voxel approach which does not assume dataset homogeneity. The new opacity correction avoids the dataset homogeneity assumption by introducing a new opacity correction factor for the samples in each voxel. Its performance improvement over the existing opacity correction approach is also exhibited for real volumetric datasets.

متن کاملParallel Ray Casting of Visible Human on Distributed Memory Architectures
This paper proposes a new parallel ray-casting scheme for very large volume data on distributed-memory architectures. Our method, based on data compression, attempts to enhance the speedup of parallel rendering by quickly reconstructing data from local memory rather than expensively fetching them from remote memory spaces. Furthermore, it takes the advantages of both object-order and image-orde...
متن کاملAdaptive Screen-Space Sampling for Volume Ray-Casting
This work is concerned with adaptive screen-space sampling for volume ray-casting. The goal is to reduce the number of rays being cast into the scene and, thus, the overall number of sampling points. We guarantee reliable images through explicit error control using an error estimator that is founded in the field of finite element methods (FEM). FEM theory further provides a well-founded theory ...
متن کاملVolume Rendering for Computational Fluid Dynamics: Initial Results
1.0 Abstract This work describes a direct volume rendering technique adapted for visualization of results from Computational Fluid Dynamics (CFD) flow solvers. The problem is difficult for at least three reasons: (1) the shapes of the grids, (2) vector as well as scalar data fields, and (3) the types of features of interest. In addition, the data set sizes are often between ten and one hundred ...
متن کاملHierarchically Accelerated Ray Casting for Volume Rendering with Controlled Error
Ray casting for volume rendering can be accelerated by taking large steps over regions where data need not be processed at a ne resolution. A new implementation is described that utilizes both a user-speciied data importance and a high-level data model in appropriate regions to achieve acceleration. Previously reported work exploited high accumulated opacity, transparency, and nearly constant v...
