Fast Rendering of Subdivision Surfaces

Here are the slides that I presented for a Technical Sketch at SIGGRAPH '96. I have also added to each page a narrative I prepared for the talk.

You can also get the paper (96kB compressed, 2.4MB full) and the color plates (0.9MB compressed, 9.5MB full). The paper was published in 7th Eurographics Rendering Workshop, Porto, Portugal, pages 61-70 and 282, June 1996.

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.
