Real-time high quality volume isosurface rendering

Abstract:

We present a volume format which is capable of representing complex reconstructions as well as a fast isosurface rendering algorithm. Our volume format consists of a set of densely packing tetrahedral polynomials in Bernstein form, each constrained to provide continuity across face boundaries. We define a specific class of tetrahedral partition suitable for our method, along with a least-squares approximation method to generate data in this format as approximations to arbitrary continuous volumes. Our volume format is closed under convolution with scalar volumes, so by representing reconstruction filters in our format we can create convolved volumes easily. We also present a fast rendering algorithm which maintains interactive rates for most volumes up to 1283 resolution. Our results include analytic and observational error for how our format approximate several common volume reconstructions, as well as space requirements and rendering speed.

About ProQuest Dissertations & Theses
With over 2.3 million records, the ProQuest Dissertations & Theses (PQDT) database is the most comprehensive collection of dissertations and theses in the world. It is the database of record for graduate research.

The database includes citations of graduate works ranging from the first U.S. dissertation, accepted in 1861, to those accepted as recently as last semester. Of the 2.3 million graduate works included in the database, ProQuest offers more than 1.9 million in full text formats. Of those, over 860,000 are available in PDF format. More than 60,000 dissertations and theses are added to the database each year.
