Church of Panagia Acheiropiitos - St. Paraskevi chapel (Basilica’s baptistery) (3D)
|
|
This is a 3D model at various resolutions (ultra low, low, medium, high, RAW) of a proktisma, attached to the south side of the church of Panagia Acheiropiitos,. Today, this is a chapel dedicated to St. Paraskevi. At first, scholars identified it as the basilica’s baptistery, while more recent studies identify it as the church’s diaconicon. Originally it must have had mosaic ornamentation to a great extent, as a preserved fragment indicates.
The church of Panagia Acheiropiitos, a UNESCO World Heritage Monument, is located on Hagias Sofias Street, in the central part of the “intra muros” city of Thessaloniki. The church lies north of the main city road, the Byzantine Leoforos (Egnatia Street today), and very close to it.

| Name | Ultra Low resolution 3D model of the Church of Panagia Acheiropiitos - Baptistiri |
| Description | This is a ultra low resolution 3D digital replica of a proktisma attached to the south side of the church, considered the baptistery of the basilica in one aspect and in another, the original ministry of the church. The church of Panagia Acheiropiitos, a UNESCO World Heritage Monument,is located on Hagias Sofias Street, in the central part of the intra muros city of Thessaloniki. The model is aimed for visualisation purposes in low end hardware and it is stored in the X3D file format that carries colour information using the texture mapping approach. It has been digitised using a multi-image based 3D reconstruction approach (Structure from Motion/Multi-Image Dense Stereo 3D Reconstruction). |
