The role of descriptive geometry in contemporary 3D modeling of cultural heritage objects

Abstract

Contemporary graphic design is necessity in each area of cultural heritage research. However, descriptive geometry procedures are substantial and irreplaceable tool for precise construction and presentation of 3D models of existing or virtual objects in cultural heritage area. Two examples of ruined medieval Serbian churches were given where the principles of Descriptive geometry were applied during creative 3D modeling processes of proposed reconstruction design. Based on the collected data from in situ measurements, the proposal is given in the form of horizontal/vertical plan and section solutions with respect to the style characteristics of similar cultural heritage objects of the Serbian medieval time. Geometric primitives were combined in creation of conceptual inner and outer spatial architectural structure of the church. The inner structure combined mostly prismatic, cylindrical and spherical shapes/solids, while the outer structure consisted of prismatic, pyramidal and conic shapes/solids. In the reconstruction process of these two structures, the position, shape and size of non existing parts of devastated objects were explored, along with their proportions and mutual spatial relations. The optimal solutions for prototype 3D modeling techniques were defined, as the contribution to geometric research in the field of cultural heritage on Serbian teritory.
