Abstract
A set of calculation methods has been developed and tested to provide means of creating virtual copies of three dimensional (3D) historical objects with minimal user input. We present a step by step data processing path along with algorithm description required to reconstruct a realistic 3D model of a culturally significant object. The important feature for archiving historical objects is the ability to include both information about its shape and texture, allowing visualization using arbitrary conditions of illumination. Data samples used as input for the processing method chain were collected using an integrated device consisting of shape, multispectral color and simplified BRDF measurements. To confirm the usability of presented methods, it has been tested by example of real life object - statue of an ancient Greek goddess Kybele. Additional visualization methods have also been examined to render a realistic virtual representation satisfying intrinsic surface properties of the investigated specimen.
