Workshop Description
There has been recently considerable interest in methods for progressively delivering 3D surface geometry across a network or to a display terminal. A few techniques have been proposed in the past few years, which can be broadly classified as methods based on polygonal surfaces or wavelets. It is a particularly good time to discuss these issues now, because of the current interest in visualization of large surface datasets, e.g. geographic data sets. Also, there is considerable activity in the standardization of such techniques, for instance in VRML and MPEG.
The purpose of this workshop is to bring together experts involved in approaches using polygonal surfaces as well as approaches using wavelets for visualization problems involving geometric data where the issue of progressive transmission or display is important. We will attempt to answer the questions listed below, as well as other questions that the participants feel important to address:
- What is the relation between wavelet-based approaches and polygonal surface based approaches for progressive transmission of 3D geometry? Are they fundamentally the same? Is one approach superior to the other?
- How can progressive transmission and view-dependent refinement of 3D geometry work together best?
- How do current methods handle singular (non-manifold) input geometry?
- Is it important to change the topology during progressive transmission?
- How to cope with lost packets during transmission (assuming a protocol allowing that is used)? How to adapt the resolution to the transmission bandwidth?
- Are progressive transmission methods ready for standardization?
We are planning to write a report on this workshop and publish it
in a prominent journal or magazine. We may also decide to publish the proceedings.
If you wish to participate..
"Vis" requires that we limit participation to 20 people. As the workshop is scheduled to last 4 hours, we will do half talks and half discussion. We would like interested people to submit a 2 page abstract if they want to give a talk, or 2 page statement if they want to participate to the discussions without giving a talk.
If you wish to participate, please send your submission by August 15th 1998 to gueziec@watson.ibm.com, either in postscript or pdf form. Feel free to send us e-mail for any further inquiry.
