Thanks, I found the plug_in API in your help document. if you have some real examples, it's great.

by the way, in your help document ,under Avatar object,it shows
"The avatar library also includes tools to integrate custom heads made with 3DMeNow Professional software by www.biovirtual.com. This software let you create a realistic head of a person from a front and profile photograph."

but I cannot find the tools( to integrate my file made with 3DMeNow )
