This paper describes a technique to enable live migration of virtual machines over the Internet. The method assumes the network supports Mobile IPv6 and that participating host devices support Xen 3.1. Unlike live migration schemes proposed by other researchers, virtual networks are not required. We describe our work in progress on developing a system that(More)
Two new shadow generation techniques are introduced to produce realistic, perceptually correct soft shadows. Penumbra volume mapping and penumbra volume mask filtering exploit modern programmable graphics hardware and are able to shadow dynamic scenes at real-time rates. Penumbra volumes extend previous sampling based approaches by masking regions where(More)
