    摘要: Abstract. In this work, we have developed a real-time camera control module
    for navigation in virtual environments. With this module, the tracking motion of
    a third-person camera can be generated automatically to allow a user to focus
    on the control of an avatar. The core of this module consists of a motion planner
    that uses the probabilistic roadmap method and a lazy update strategy to
    generate the motion of the camera, possibly with necessary intercuts. A dynamic
    roadmap specified relative to the avatar is updated in real time within a
    time budget to account for occlusions in every frame of the control loop. In addition,
    the planner also allows a user to specify preferences on how the tracking
    motion is generated. We will use several examples to demonstrate the effectiveness
    of this real-time camera planning system.
