VIlMI Brnm On-Line Performance Stephen N. Matsuba VR Studios In the late summer of 1997, Stephen N. Matsuba and Bernie Roehl began an ambitious project: to create a new e n t e r t a i n m e n t medium, without funding and together with a dedicated group of volunteers situated all around the world. The project sought to present a live performance of Shakespeare'sA Midsummer Night's Dream using real-time 3D animation multicast over the Internet. The sets, props and all the characters are optimized VRML models. A group of actors provided the voices and eight "puppeteers" controlled the characters' movements. The voice and the motion data were digitized, compressed and sent out over the Internet in real time. Moreover, people were able to access this multicast with a 28.8K modem connection and a 150 MHz Pentium computer. Less than six months after its inception, VRML Dream made "lnternet history" [I] as the first live, streaming, entertainment project with a running time of more than two or three minutes. Two key problems presented themselves in the d e v e l o p m e n t of this project. One concerned the 3D models
