Improved appearance rendering for photogrammetrically acquired 3D models

In this paper we present a technique for significantly improved rendering of objects scanned using photogrammetry techniques. We demonstrate the connection between photogrammetry and the unstructured lumigraph, a surface light field representation and rendering algorithm. We use our lumigraph rendering software to demonstrate improved results from photographically acquired cultural heritage artifacts. We discuss our improvements to the rendering of unstructured lumigraphs on modern hardware and offer this rendering tool as free, open source software.
