Applying constraint weighting to autonomous camera control

Automating camera control for third-person perspec-tive computer games is a difficult and time-consuming task. One of the challenges games developers confront is how to manage the trade-off between implementation complexity and system usability. In this study, we in-vestigate the application of constraint weighting tech-niques to the autonomous camera control problem. We demonstrate that this technique can significantly sim-plify autonomous camera control and reduce the gap be-tween implementation and usability requirements. We describe the use of weighting profiles to control the behaviour of the camera and specialized heuristics for efficiently searching for the solution. We also de-scribe a novel integrated visibility maintenance method. As part of the experimental study, we implemented a 3D game engine that supports dynamic environments; and demonstrate the effectiveness of the use of con-straint solving techniques for autonomous camera con-trol problems
