CubeCam: A Screen-space Camera Manipulation Tool

Abstract

We present CubeCam, an image-space camera manipulation widget that uses a projected cube to both visualize the relationship of the camera to the scene and as an interaction tool to change that camera. The cube geometry reflects the use of perspective lines by artists in order to establish the scene projection. We allow the user to interactively change the camera by changing the cube's projection in the image plane. We incorporate pie menus, ghosting, and a crossing-style interface to reduce mouse movement and make it simpler for novice users to learn and experiment with the interface. Finally, we provide a novel method for visualizing camera bookmarks.
