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 of virtual environments within other real-time virtual environments. Their flexibility arises from a combination of temporal, spatial and presentational properties. Temporal properties determine the relationship between time in a live environment and time in a recording, including the apparent speed and direction of replay. Spatial properties determine the spatial relationship between the environment and the recording. Presentational properties determine the appearance of the recording within the environment. These properties may be fixed, dynamically varied by an application, or directly controlled in real-time by users. Consequently, temporal links have a wide variety of potential uses, including supporting post-production tools for virtual environments, post-exercise debriefing in training simulators, and asynchranous communication such as VR email, as well as providing new forms of content for virtual worlds that refer to past activity. We define temporal links and their properties and describe their implementation in the MASSIVE-3 Collaborative Virtual Environment (CVE) system, focusing on the underlying record and replay mechanisms. We also demonstrate applications for adding new content to an existing virtual world, and a VR post-production editor.
虚拟现实(VR)当前缺少通常可用于视频和音频等已建立媒体的复杂生产技术。本文介绍了时间链接的概念,它为在其他实时虚拟环境中重放虚拟环境的过去或最近记录提供了一种灵活的机制。它们的灵活性源于时间,空间和表现属性的组合。时间属性决定了实时环境中的时间与录音中的时间之间的关系,包括视在速度和重放方向。空间属性决定了环境与记录之间的空间关系。外观属性决定了记录在环境中的外观。这些属性可以是固定的,可以由应用程序动态更改,也可以由用户实时直接控制。因此,时间链接具有广泛的潜在用途,包括支持虚拟环境的后期制作工具,训练模拟器中的演习后汇报,以及VR电子邮件等异步通信,以及为虚拟世界提供新形式的内容,指过去的活动。我们定义了时间链接及其属性,并描述了它们在MASSIVE-3协作虚拟环境(CVE)系统中的实现,重点是基础的记录和重播机制。我们还将演示用于向现有虚拟世界添加新内容的应用程序以及VR后期制作编辑器。 P>
