Abstract: This paper presents the use of cinematographic and geometric measures for determining the path of a virtual camera for the generation of computer graphics video sequences focused on showing an underwater shipwreck. This work rises from the applied challenge of mapping underwater shipwrecks, reconstructing a computer graphics model then creating an educational visualization of the wreck. The primary algorithm presented in this work computes the optimal camera pitch and height along a path utilizing a probabilistic roadmap (PRM) that weights nodes using a computational models of cinematographic and geometric principles. These principles were used to evaluate potential viewpoints and influence whether or not a view is used in the final path. Specifically, the algorithm uses a computational evaluation of the cinematographic ‘rule of thirds’ and a geometric evaluation of the model normals relative to the camera viewpoint. A user study of video output from the system suggests that our compu ted paths are ranked higher than simple circular or random paths and that the ‘rule of thirds’ is a more important criteria than the geometric principle explored.
