The IBar: A Perspective-based Camera Widget
Published in Proceedings of the 17th annual ACM symposium on User interface software and technology, 2004
The first draft of the IBar. <a href=\"./IBar\">Source code</a> and more implementation details. We present a new screen space widget, the IBar, for effective camera control in 3D graphics environments. The IBar provides a compelling interface for controlling scene perspective based on the artistic concept of vanishing points. Various handles on the widget manipulate multiple camera parameters simultaneously to create a single perceived projection change. For example, changing just the perspective distortion is accomplished by simultaneously decreasing the camera\\s distance to the scene while increasing focal length. We demonstrate that the IBar is easier to learn for novice users and improves their understanding of camera perspective. Camera control
