3D 图形技术的进步加速了动态 3D 环境的构建。尽管它们在科学和教育应用方面做出了承诺，但由于运行时相机控制软件缺乏用户敏感性，大部分潜力尚未实现。当前的环境依赖于直接需要用户控制的视点序列，或者主要基于场景的动作和几何形状。由于快速变化的环境的复杂性，用户通常无法在发出相机控制命令的同时操纵环境中的对象。为了解决这些问题，我们开发了 UCam，这是一种实时摄像机规划器，它采用电影用户模型来渲染动态 3D 环境的定制可视化。在采访用户以确定他们喜欢的导演风格和节奏后，UCam 检查由此产生的电影用户模型，以规划摄像机序列，其拍摄有利位置和剪辑速率是根据用户实时定制的。对 UCmin 动态 3D 测试平台的评估令人鼓舞。
Advances in 3D graphics technology have accelerated the construction of dynamic 3D environments. Despite their promise for scientific and educational applications, much of this potential has gone unrealized because runtime camera control software lacks user-sensitivity. Current environments rely on sequences of viewpoints that directly require the user’s control or are based primarily on actions and geometry of the scene. Because of the complexity of rapidly changing environments, users typically cannot manipulate objects in environments while simultaneously issuing camera control commands. To address these issues, we have developed UCam, a realtime camera planner that employs cinematographic user models to render customized visualizations of dynamic 3D environments. After interviewing users to determine their preferred directorial style and pacing, UCamexamines the resulting cinematographic user model to plan camera sequences whose shot vantage points and cutting rates are tailored to the user in realtime. Evaluations of UCamin a dynamic 3D testbed are encouraging.
