Implementation and evaluation of an interactive volume visualization system on a lightfield display.

Multiscopic visualization is an emerging display technology that aims to reproduce three dimensional scenes by generating observer independent light fields. Here, we will report on a volume visualization system that can drive a display of this class to fully support direct, interactive, 3D volume rendering of high resolution, 16 bits, very large medical datasets (10243 voxel and more). As a matter of example, figure 1 shows the inspection of a large volumetric model containing a CT dataset (1024 × 1024 × 1080 with 16 bits/sample) of a biological specimen 3 . Moreover, we report on the preliminary results of a series of evaluation tests aimed to investigate the depth discrimination capability of the system. The perceptual evaluation indicates that this class of volume visualization system provides correct stereo cues, layout discrimination and it is clearly superior to two dimensional displays for path tracing tasks such as the understanding ofvascular structures.
