Recording devastated objects consists of three phases: recording existing remains, recording collapsed parts of objects and combining these results into a complete
model.
Optimal method for recording existing remains depends on the specific site conditions. Criteria for choosing optimal method can be divided into project criteria, economic criteria and object criteria. Project criteria relays on required type of representation which includes data quantity, quality and complexity. Economic criteria searches for method with least time and financial demands. Object criteria analyze if the defined type of objects is suitable for specific method. After complete analysis of numerous devastated sacral objects, it is determined that among manual measuring, photogrammetry and laser scanning, the terrestrial photogrammetry is the
best method,. For recording of former object appearance, old photograph restitution is obviously the optimal method.
Combining photo restitution, terrestrial photogrammetry and modeling, virtual reconstructions of partly collapsed objects are
created. Virtual reconstruction of devastated objects is a 3D model representing object as it looked before any damage.
Danube area of Vojvodina was entirely researched as case study . All catholic churches and chapels built in Vojvodina in 18th, 19th and first half of 20st century were recorded. For devastated objects virtual reconstructions were made. These models relay on 3D photogrammetry models of present remains combined with object volume data on old photographs or photographs of hardly approachable parts. Several typical object representatives are presented in this paper.

In this paper, some common ambiguities in the area of the historical architectural environments are highlighted. In most approaches user is the one to introduce and choose
constraints, and therefore he must have control over the ambiguity problems. We propose suggestions about how to adjust the single-image-based modeling in order to minimize chance for irregular 3D shapes to emerge due to ambiguity. Simple examples are used to illustrate how ambiguity of a single image can affect the models veridicality, which are the common mistakes that inexperienced user can make and how and when they can be corrected

New concepts of space, different from the three-dimensional Euclidean space, have had an impact on architecture since the beginning of the 20th century. Similarly, at the end of the 20th century the concept of topological space had great influence on architecture. In recent years some new concepts of space in architecture have emerged from the growing interest in complexity science. Fractal geometry and dynamic systems create a new paradigm in the architectural theory and design. The notion of heterogeneous space that some architects suggested, attempts to lay the groundwork for spatial complexity within architecture.
In this research the influence of geometric concepts of space on the theory of design and representation in architecture are examined. The paper systematically describes, analyzes and evaluates the claims of individual architects who applied concepts of space different from the three-dimensional Euclidean in their design. While such claims are widespread among contemporary and late twentieth century architects, they stand for a great variety of design strategies and it is not always certain that they are mathematically justified. In this paper the relationship between mathematical concepts of space and architectural design and representation are evaluated in order to show and the extent to which they are really related.
