Mix-N-Match Motion: Animating Virtual Experiences

美国威斯康星州麦迪逊市的迈克尔·格雷切尔（Michael Gleicher）：随着世界上的危险变得越来越明显，我们越来越渴望为它们做好准备，对虚拟体验的需求也越来越大：模拟环境向参与者传达他们所处的环境，而不仅仅是一个地方。虚拟体验可以提供一个机会去探索那些太危险而无法排练，太不切实际而无法创造，或者太不方便而无法参加的情况。它们可以用于培训，例如，为应急响应人员提供指挥恐慌人群的第一手经验;用于设计，例如，在建造之前确定人们如何与空间互动;或用于娱乐。虚拟体验的关键在于它们将环境和情境联合收割机结合起来。简单地创造一个视觉上引人注目的虚拟环境是不够的。我们的愿景是在培训，研究和娱乐中使用引人注目的虚拟体验。为了在这些应用中有效，虚拟环境必须被创作以满足特定的教学和通信目标。因此，实现这一愿景需要模拟和渲染世界的技术，并使作者能够有效地指定行为。

ABSTRACT0204372Michael GleicherU of Wisconsin-MadisonAs the dangers of our world become more apparent, and our desire to prepare for them increases, there is agrowing need for virtual experiences: simulated environments that convey to a participant the sense that theyare in a situation, not just a place. A virtual experience can provide an opportunity to explore a situation thatis too dangerous to rehearse, too impractical to create, or too inconvenient to attend. They may be used fortraining, for example to give first hand experience to emergency response personnel in directing panickedcrowds; for design, for example to determine how people interact with a space before it is constructed; orfor entertainment. The key to a virtual experience is that they combine environment and situation. Simplycreating a visually compelling virtual environment is insufficient.Our vision is to use compelling virtual experiences in training, research and entertainment. To be effec-tive in these applications, virtual environments must be authored to meet specific pedagogical and commu-nicative goals. Realizing this vision, therefore, requires technologies for both simulating and rendering theworlds and enabling an author to specify behavior effectively.
