Multilingual 3D avatars combine rich emotion with multi-lingual speech gesticulation. They require complex animation. The most performing facial animation engines for avatars have been developed using morphing techniques. Unfortunately, these techniques cannot be directly utilized to generate animation through the Internet. The information needed to make them work is over the capacities of the connections of most Internet users. This article presents a solution to this problem. We have elaborated the adaptation of a very performing multilingual face animation engine to fit it into the Internet. We also evaluate the pros and the cons of such an adaptation from the animation quality perspective
