Abstract
In this paper we present a two-level approach for
fusing direct
volume rendering (DVR) and maximum-intensity projection (MIP)
within a joint rendering method.
Different structures within the data-set are rendered locally by
either MIP or DVR on an object-by-object basis. Globally all the
results of subsequent object renderings are combined in a merging step
(usually compositing in our case). This allows to selectively
choose the most
suitable technique for depicting each object
within the data, while keeping the amount of information contained in
the image at a reasonable level.
This is especially useful when inner
structures should be visualized together with semi-transparent outer
parts, similar to the focus-and-context approach known
from information visualization. We also present an implementation of our
approach, which allows to explore volumetric data using
two-level rendering at interactive frame rates.
