Direct Volume Rendering from Photographic Data

We present a technique to extract regions from a volumetric dataset without introducing any aliasing so that the extracted volume can be explored using direct volume

– 2D textures for accumulating color and opacity – Access volume data from 3D texture map. • Additional pass for

The sequence of difference images is in itself a volume data set, and can be used to assist in the visualisation of the original video data set.. In the next section, the

Figure 4 shows the tooth data set rendered with gradient- magnitude opacity-modulation, direct volume rendering us- ing a clipping plane, and context-preserving volume render- ing

Starting out with a segmented volume, for each and every object within the data, an individual ren- dering mode – ranging from direct volume rendering through

Nevertheless, to our knowledge, no isosurface extraction method exists that directly extracts surfaces from scattered volume data without 3D mesh generation or reconstruction over

Traditional direct volume rendering techniques consist in in- tegrating opacity and color values along a viewing ray by using a simple light transport model, called the volume

Their potential to cleverly generate a color and opacity value for direct volume rendering is primarily determined by the used metrics besides the input data value.. Despite
