Temporal Links: Recording and Replaying Virtual Environments

摘要

Virtual reality (VR) currently lacks the kinds of sophisticated production technologies that are commonly available for established media such as video and audio. This paper introduces the idea of temporal links, which provide a flexible mechanism for replaying past or recent recordings fo virtual environemtns within other real-time virtual environments. Their flexibility arises from a combination fo temporal, spatial and presentational properties. Temporal properties determine the relationship between time in a live environemtn and time in a recording, including the apparent speed and direction of replay.
