I know this is isn't a Performer question but I do not know who else to ask. I tried the comp.sys.sgi.graphics newsgroup but got no response.

Can anyone explain how the demo "distort" in buttonfly is implemented? It's under the Performance Features, Reality Engine buttons. It is a texture of a dog that you can pick with the mouse and cause a ripple effect or a rubber effect.

I am interested in creating that same effect in a Performer application. I am assuming I will use a pfGeoSet and change the texture coordinate array. Maybe thistype effect can only be done through a GL object? Any suggestions are welcome.

Thanks in advance,

Pat
