Efficient visualization of large volumetric data is a challenge for image processing community. In this paper, we present a novel volume rendering algorithm based on the concept of fractal. It consists of dividing the volumetric data set into sub-blocks, calculating the 3D fractal coefficients of each sub-block, projecting them to 2D image plane, and ...

A technique for rendering images of volumes containing mixtures of materials is presented. The shading model allows both the interior of a material and the boundary between materials to be colored. Image projection is performed by simulating the absorption of light along the ray path to the eye.

Presents a two-level approach for volume rendering, which allows for selectively using different rendering techniques for different subsets of a 3D data set. Different structures within the data set are rendered locally on an object-by-object basis by either direct volume rendering (DVR), maximum-intensity projection (MIP), surface rendering, value ...

Analyzing and processing various data types in a privacy-preserving perspective has been researched in many disciplines; however, such an issue draws very limited attention in the research field of scientific visualization. We wondered if it is possible to delegate the rendering of a volume data set to a remote server(s) while still being able to ...

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 ...

Volumetric rendering speaks volumes for data 20 orders of magnitude apart—from human anatomy to neuroanatomy, and from electrostatic charges of macromolecules to failure analysis of manufactured parts.

To what extent can the exact size and form of an object be reconstructed from volume data? Why can the rendering of a 3D dataset performed with a super-resolution volume rendering algorithm be magnified beyond the dimensions of the individual voxels without introduction of artefacts and/or unsharpness?

This document might be out of date, please check online for an updated version. With significant advances in techniques, along with increasing computational power, path tracing has now become the predominant rendering method used in movie production. Thanks to these advances, volume rendering can now take full advantage of the path tracing revolution ...

Sort-First Parallel Volume Rendering
IEEE Transactions on Visualization and Computer Graphics, 2011Sort-first distributions have been studied and used far less than sort-last distributions for parallel volume rendering, especially when the data are too large to be replicated fully. We demonstrate that sort-first distributions are not only a viable method of performing data-scalable parallel volume rendering, but more importantly they allow for a ...

In this paper we describe the extension of a parallel, distributed, direct volume renderer for use with a novel auto-stereoscopic display. We begin by briefly describing the target application of our research, radiation therapy planning, why we believe that stereoscopic viewing may be helpful for this, and the design of our DVR system.
