| Abstract: | 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. |
