Abstract

The article deals with issues of applying modern innovative three-dimensional techniques in production and restoration of facade decor elements. Methodology for producing an exact physical copy of a part under restoration is set forth as exemplified by the architectural rosette. It details a methodology of how to conduct virtual digital restoration of a rosette using one of the best software solutions for digital molding, Zbrush, which is a superb tool to create high-definition three-dimensional objects. Two methods of digital restoration are treated: copying and sculpting. The copying method produces the geometric shape of an article consisting of items with identical dimensions. Sculpting is performed using digital molding, i.e. working with digital clay – a more intuitive modeling method compared to traditional techniques. Possible methods of production of the restored physical copy of a damaged rosette, their merits, and demerits are described. The study provides a forecast for development of architectural monument restoration with the use of three-dimensional techniques.
