Corrects a virtual cameras flight path when an objects orientation is not aligned with its own motion path, for smoother virtual scene camera work.
A method includes receiving a first motion path for an object,where an orientation of the object is not aligned with the first motion path for the object for at least a portion of the first motion path. The method also includes receiving a first motion path for a virtual camera and determining a speed of the object along the first motion path for the object. The method additionally includes calculating a second motionpath for the object based on the speed of the object along the first motion path for the object and the orientation of the object, where the second motion path of the object is aligned with second motion path. The method further includes calculating a second motion path for the virtual camera based on a difference between the first motion path of the objectand the second motion path of the object.
