This paper presents an interactive rendering technique for detail+overview visualization of 3D digital terrain models using interactive close-ups. A close-up is an alternative presentation of input data varying with respect to geometrical scale, mapping, appearance, as well as level-of-detail and level-of-abstraction used. The presented 3D close-up approach enables in-situ comparison of multiple region-of-interest simultaneously. We present a GPU-based rendering technique for the image-synthesis of multiple close-ups in real-time.
