Abstract:
A system and method for camera navigation that provides a player with an unobstructed, non-disorienting view of a target is provided. The system includes a memory for storing a camera navigation/control model, a central processing unit for executing the camera navigation/control model to provide unobstructed and non-disorienting target character views, and a graphics processing unit configured to render the unobstructed views of the target in an image for display. In addition, the camera navigation/control model includes an object detection model, line-of-sight restoration models to restore a line-of-sight view of an obstructed target, and a camera navigation path model. In the method, a collision probe is sent on a straight line path between a camera and a target whereby line-of-sight obstructions are detected if the probe intersects with polygonal sides of an object. A line-of-sight restoration method is used to move the camera to provide an unobstructed view of the target.
