A system and method of determining data representing a mapping of optical signals described by image data of a reflecting surface of a structure to a three-dimensional surface geometry of the reflecting surface is provided. At least first, second and third light sources are provided, comprising a broadband point light source, a spectrally variable point light source and a movable linear broadband light source, respectively. First, second and third images are acquired, corresponding to each light source. Surface geometry data describing a three-dimensional surface geometry of the reflecting surface is acquired. Based on the image data and the surface geometry data, reflecting surface mapping data describing a mapping between the reflections described by the first image data, second image data and third image data, and the three-dimensional surface geometry of the reflecting surface is determined.

Method and apparatus for digitizing the appearance of a real material

A visualization device is provided that includes an actual light box that includes an illumination array for illuminating an actual object (O) placed in the actual light box; and a rear limiting wall which functions as a screen. The device also includes a computer programmed to spatially display a virtual light box on the screen, such that the virtual light box displayed on the screen appears to form a continuous rearward extension of the actual light box. In addition, a virtual object (O) may be displayed on the screen, such that the virtual object (O) is situated in the virtual light box. The combination of an actual light box and a virtual light box allows an observer to realistically assess appearance data rendered onto a virtual object, in a direct comparison with an actual object.

Visualization device for displaying a rendered virtual object

The present invention provides a method of digitally generating, via the use of a computer, data indicative of a synthesized appearance of a simulated material having physically plausible appearance attributes. The method includes determining a set of data indicative of the synthesized appearance of the simulated material based at least in part on data associated with the physically tangible source material and at least in part on data of measured attributes of the physically tangible reference material.
