Abstract
Embodiments alter the swoop trajectory depending on the terrain within the view of the virtual camera. To swoop into a target, a virtual camera may be positioned at an angle relative to the upward normal vector from the target. That angle may be referred to as a tilt angle. According to embodiments, the tilt angle may increase more quickly in areas of high terrain variance (e.g., mountains or cities with tall buildings) than in areas with less terrain variance (e.g., flat plains). To determine the level of terrain variance in an area, embodiments may weigh terrain data having higher detail more heavily than terrain data having less detail.
