我们已经创建了一个自动摄影系统的交互式虚拟环境。该系统控制一个虚拟摄像机，并在一个由一组自主和用户控制的角色居住的三维虚拟世界中进行战斗。通过动态地改变相机和战斗，我们的系统促进了人类参与者与这个世界的互动，并显示数字场景的情感内容。基于传统的电影，现代视频游戏和自主行为系统，我们构建了这个电影摄影系统，具有传感器，情感，动机和动作选择机制的行为学启发结构。我们的系统将镜头分解为元素，例如相机应该聚焦于哪些演员或应该使用什么角度来观看他们。按等级排列的交叉排除组在各种选择之间进行调解，在每个时刻都能及时找到最佳选择。我们的电影摄影系统使用的方法与我们对虚拟演员使用的方法相同。这简化了它们之间的信息交叉，并最终导致更丰富和更统一的安装。随着数字可视化变得越来越复杂，电影摄影必须跟上新品种的角色和场景。基于行为的自主电影摄影系统是创建有趣的虚拟世界的有效工具。我们的工作迈出了走向互动，情感电影摄影未来的第一步。
We have created an automatic cinematography system for interactive virtual environments. This system controls a virtual camera and fights in a three-dimensional virtual world inhabited by a group of autonomous and user-controlled characters. By dynamically changing the camera and the fights, our system facilitates the interaction of human participants with this world and displays the emotional content of the digital scene. Building on the tradition of cinema, modern video games and autonomous behavior systems, we have constructed this cinematography system with an ethologically-inspired structure of sensors, emotions, motivations, and action-selection mechanisms. Our system breaks shots into elements, such as which actors the camera should focus on or the angle it should use to watch them. Hierarchically arranged cross-exclusion groups mediate between the various options, arriving at the best shot at each moment in time. Our cinematography system uses the same approach that we use for our virtual actors. This eases the crossover of information between them, and ultimately leads to a richer and more unified installation. As digital visualizations grow more complex, cinematography must keep pace with the new breeds of characters and scenarios. A behavior-based autonomous cinematography system is an effective tool in the creation of interesting virtual worlds. Our work takes first steps toward a future of interactive, emotional cinematography.
