Abstract:
Simulating hand-drawn illustration techniques can succinctly express
information in a manner that is communicative and informative.
We present a framework for an interactive direct volume
illustration system that simulates traditional stipple drawing. By
combining the principles of artistic and scientific illustration, we
explore several feature enhancement techniques to create effective,
interactive visualizations of scientific and medical datasets. We also
introduce a rendering mechanism that generates appropriate point
lists at all resolutions during an automatic preprocess, and modifies
rendering styles through different combinations of these feature enhancements.
The new system is an effective way to interactively
preview large, complex volume datasets in a concise, meaningful,
and illustrative manner. Volume stippling is effective for many applications
and provides a quick and efficient method to investigate
volume models.
