camera morph

The problem of having to orient the camera towards one interesting object after another in the course of a camera motion. This can be done tediously using a Spline along which the camera moves or easily using the Camera Morph tag. Simply create several cameras - that can also be animated - for the regions you want to show and use the Camera Morph tag to automatically create separate animated cameras (incl. their most important parameters such as Focal Length). Morphing = steplessly assuming other states.
