Volume visualization and exploration through flexible transfer function design

Direct volume rendering (DVR) is a well-known method for exploring volumetric data sets. Optical properties are assigned to the volume data and then a DVR algorithm produces visualizations by sampling volume elements and projecting them into the image plane. The mapping from voxel values to optical attribute values is known as transfer function (TF). Therefore, the quality of a visualization is...

Automatic Adjustment of Transfer Functions for 3D Volume Visualization

In most volume rendering scenarios implicit classification is performed manually by specification of a transfer function, that maps abstract data values to visual attributes. An appropriate classification requires both specialized knowledge of the interesting structures within the data set as well as the technical knowhow of the computer scientist. Recent automatic data-driven techniques are ve...

Clustering for Parallel Volume Visualization

Volume visualization is a powerful engineering tool. However, the visualization of a three dimensional volume is computationally expensive taking significant amounts of time to produce the images on conventional computers. Parallel processing offers the possibility of rendering the volume in acceptable times. This paper discusses hierarchical and distributed clusteral models with dynamic cluste...

The SSE Histogram: Transfer Function Specification for 3D Volume Visualization

Direct volume visualization requires the definition of transfer functions (TFs) for the assignment of opacity and color. Multi-dimensional TFs are based on at least two image properties, and are specified by means of 2D histograms. In this work we propose a new type of a 2D histogram which combines gray value with information about the size of the structures. This Structure Size Enhanced (SSE) ...

Automatic transfer function design for medical visualization using visibility distributions and projective color mapping

Transfer functions play a key role in volume rendering of medical data, but transfer function manipulation is unintuitive and can be time-consuming; achieving an optimal visualization of patient anatomy or pathology is difficult. To overcome this problem, we present a system for automatic transfer function design based on visibility distribution and projective color mapping. Instead of assignin...
