We started with reconstruction of Michael Archangel cathedral for the period of 1920th. First step of reconstruction is digitalizing of blueprints in Autodesk AutoCAD™. Previously some of them were scaled and cropped in Photoshop. All blueprints were with defects: faded colors, paper cast and so on. Second step is modeling in Rhinoceros. Firstly we cre- ated main form of all buildings. Secondly,we modeled in- ner walls for creating interior of this monastery. There are some problems with interpretation of historical sources. Some of them contains various readings andwe prefer photo if there are some sources. Most of problems deals with decor elements. [2] Vizualisation All surfaces were exported from Rhinoceros to 3D Studio Max for the photorealistic rendering to be car- ried out. In this program we created all material (texture maps based on real images)accordingto historical sour- ces or survived analogs and visualized model via Vray plugin(Fig.2-3)[3] Using this 3D technology we don`t seek to replace of the real historical objects with this model. No, even the most rigorous scientific reconstruction, can not act as the equivalent of a genuine monument. The purpose of the renovations - is to recreate (stored in electronic form) that has been lost. The digital model has one indisputable ad- vantage - it does not get old, does not break and can be kept forever. Project results will be present as a part of virtual mu- seum of lost Moscow.
