"We zijn niets anders dan strandvonders van ons eigen leven, brokstukken verzamelend langs de zee der vergetelheid. In onze hand lopen wij met de verroeste spijkers van een groot, gezonken schip – en wij denken dat dit oudroest een horloge is."

Willem Frederik Hermans

Polynomial Texture Mapping (PTM)

Polynomial Texture Mapping (PTM) is a technique that enables the production of detailed surface models of particular artefacts from a series of digital photographs (Malzbender et al 2001; Mudge et al 2005). This technique is achieved by taking multiple photographs of an object from a fixed location, with a controlled light source moved between each exposure, or by deriving the light source's location and orientation from highlights appearing on a reference object. The resulting series of images is used to produce a single PTM file via the HP Labs PTM fitter software. The PTM viewer enables a virtual light source to be moved across the virtual scene. The viewer can also vary lighting intensity, add additional virtual lights, derive surface models and to carry out image processing tasks such as edge detection.
