IBRelight is an interactive image based rendering program that allows archivists to create realistic pictures of shiny, inhomogeneous, and three-dimensional cultural heritage artifacts from flash photographs of those objects. The software provides an easy to use interface that has features similar to those provided by existing computer graphic rendering packages, but it is built on previously developed technology that can generate new images from novel viewpoints while relighting the object using point light and environmental lighting setups. Because the rendered image is created directly from the original photographs, it retains the visual fidelity of those photos, and the rendered tristimulus values can be interpreted using color management information archived with the flash photographs.
