The Kamanli Yahsi Bey Bath in Kamanli, Urla, was chosen for the design studio course, Res 506, of the Restoration Graduate Program. During the site visit, digital photographs were taken and then used to produce rectified images. Özge Basagaç used this material to pursue some post studio work that investigated further the application of rectification and 3D modeling. She prepared the following report.

Report on Rectification and 3D modelling of the Kamanli Yahsi Bey Hamam, prepared by Özge Basagaç.

The Urla district of Izmir, 50 km to the west, had been continuously settled for thousands of years. The prehistoric town of 3000 BC evolved into the antique city of Klazomenai. It became particularly prosperous during the period of Roman rule and remained a centre during the Byzantine Empire, the Anatolian Seljukids and then the Aydinoglu Principality.

In the early 15th century Urla passed on to the Ottomans. At that period there was a huge amount of construction activity including monumental buildings and new living quarters in and around the city. Kamanli was one of the quarters established outside the city, 2 km to the east. It originated from a building complex composed of a mosque, a bath, a "sibyan mektebi" (primary school), a "turbe" (tomb) and two fountains (Fig. 45).

In the spring semester of 2001-2002 academic year the Kamanli bath was studied by the First Year Studio of the Graduate Program of the Restoration Department. The complex was measured manually and visual surveys were carried out.

Survey drawings of the elevations were rendered using rectified photographs (Fig. 46). In the analysis phase of the study those photographs were used for mapping of structural deformations and material deteriorations (Fig. 47).

A further study on the 3 dimensional modeling of the bath and the site was carried out by Özge Basagac in the Kerkenes Office. With the help of the base maps, obtained from the municipality, the site was primarily modeled in AutoCAD and then in ArcView GIS 3.2. Site modeling allowed one to see the overall formation of the complex and the relationship between the buildings which is now obscured by plants (Fig. 48). The 3D Max program also provided a virtual fly over of the site.

The "hamam" and the "hamam" fountain were modeled in AutoCAD and the model imported into PhotoModeler 3. The digital photos of the elevations that were taken on site were rectified and then added to the PhotoModeler virtual model (Figs 49, 50, 51, 52 and 53). It must be noted that PhotoModeler does not handle the 3D rectification of curvilinear surfaces. Finally, the site model and the building models were combined in 3D Studio Max 4.

Models allow us to reach an understanding of structural behavior of the buildings. These models can also be used to map material deterioration and structural deformations. Because PhotoModeler can display deterioration and deformations in 3D, possible causes can be deduced.

Modeling can bring sites and buildings to a general public who might not be able to visit far away sites and thus enables more people to appreciate the values of cultural heritage.
