IEEE Transactions on Visualization and Computer Graphics, 2000 Volume renderers for interactive analysis must be sufficiently versatile to render a broad range of volume images: unsegmented "raw" images as recorded by a 3D scanner, labeled segmented images, multimodality images, or any combination of these. The usual strategy is to assign to each voxel a three component RGB color and an opacity value /spl alpha ...

Topology-Controlled Volume Rendering [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2007 Topology provides a foundation for the development of mathematically sound tools for processing and exploration of scalar fields. Existing topology-based methods can be used to identify interesting features in volumetric data sets, to find seed sets for accelerated isosurface extraction, or to treat individual connected components as distinct entities ...

Homomorphic-Encrypted Volume Rendering [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2021 Computationally demanding tasks are typically calculated in dedicated data centers, and real-time visualizations also follow this trend. Some rendering tasks, however, require the highest level of confidentiality so that no other party, besides the owner, can read or see the sensitive data.
