Abstract: In this paper, various methods were combined to create a morphogenetic reconstruction of Liberty Square in Novi Sad using photo documentation as input data. Three-dimensional morphogenetic reconstruction of the city square provides the most comprehensive way of tracking changes in its structure through relative time periods. Transformations of Liberty Square are followed from the year 1885 to present day. Through that period, Liberty Square has undergone dramatic changes in its shape and structure. Previous appearances of the square are known from preserved historical photographs and mapping documentation. Old photographs and new digitally captured images were combined through different modeling approaches in attempt to find the most efficient way to reconstruct characteristic development phases of the square. Existing objects are generated through the use of different styles of photogrammetric modeling; however, non-existing or modified objects are generated by application of historical photo restitution combined with 3D modeling. Adequate simultaneous usage of all methods provides optimal results.

Virtual Reconstruction of Kljajicevo Chapel

V. Stojaković, R. Štulić, 2010. Virtual Reconstruction of Kljajicevo Chapel, Journal for Geometry and Graphic, Vol. 14, No 10, pp. 81-91

Abstract: Virtual reconstruction, as a three dimensional realistic representation, has many advantages in the cultural heritage data distribution and storage, especially in the case of devastated architectural objects. A procedure of virtual reconstructing of St Wendelin chapel in Kljajicevo is presented in this paper as a case study. Existing remains have been recorded using terrestrial photogrammetry. Spatial information and dimension of collapsed parts have been exported from old photographs by using perspective projection restitution methods. These two type of data are combined and used as a platform for 3D virtual reconstruction of object. Virtual reconstruction makes spatial data complete and ready for further research or data distribution.

Optimal Methods for 3D Modeling of Devastated Architectural Objects

Abstract: In this research we define optimal methods for 3D representation of devastated architectural objects. 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.
