Here are the slides that I presented at International Conference on Recent Advances in 3-D Digital Imaging and Modeling in Ottawa in May 1997. I have also added to each page a narrative I prepared for the talk.
You can also download PostScript files for the paper (1.7MB) and the slides (compressed, 0.8MB).
These pages were created with Webify. Webify is a program which makes web-browsable trees of hypertext files and JPEG images from Postscript source files. It was motivated by the need to convert Powerpoint presentations to humane web form, such as the following simple example:
Resolution and other parameters are adjustable, allowing most any postscript file (papers, manuals, books) to be automatically converted to page-browsable form.
Webify is freely distributed in C source form, and runs on UNIX systems having Ghostscript installed with PPM conversion along with the cjpeg utility (both available free). It can be used (on UNIX systems) to convert postscript files generated on Macs, PCs, and elsewhere.
CLICK HERE to DOWNLOAD a large compressed tar file containing webify source. The size of the file stems from the postscript containing the above presentation; webify is a simple, single C program which invokes GhostScript to do most of the real work. Documentation is sparse.
