Session 7: 3D Modelling and Reconstruction

Thursday March 2, 2023, starting at 16:00 GMT = 17:00 CET (for 90 minutes)

Convenors: Gabriel Bodard (University of London), Orly Lewis (Hebrew University of Jerusalem)

Outline

This session introduces 3D modelling, the production of a 3D reconstruction of a lost, damaged or conjectured object or stucture (as contrasted to imaging, which technologically captures an existing object). In cultural heritage, broken objects may be reconstructed, lost buildings may be rebuilt from foundations, ruins or depictions using CAD software, and artefacts or bodies may be built according to the descriptions of ancient texts. Such reconstructions draw on a range of types of evidence and scholarly judgement, and therefore a detailed documentation and apparatus criticus of the model is a scholarly imperative. The session includes case studies, and a tutorial on the reconstruction of a building from ancient Pompeii using the Sketchup Make software.

Exercise

NB this exercise was written for Sketchup Make 2017, the free version of the Sketchup Desktop application. This version is now unsupported, but you can still find free downloads of the old version online (e.g. Mac, Windows). If you prefer to use the free Sketchup Web or a 30-day trial version of Sketchup Pro, please feel free but you may find some of the functionality assumed in the tutorial is very slightly different or missing. This should not impact on your ability to complete the exercise.

1. Following the introductory demo in this week's video and the PDF instructions by Valeria Vitale, work through as much of the model of the Ekklesiasterion of the Iseum in Pompeii as you can. Save your progress regularly!
2. If you have any problems or other questions, please use the forum ticket to discuss with your colleagues or classmates.

Documentation of the Ekklesiasterion model:

• PDF with photographic and other documentation for the Ekklesiasterion
• Textures for the Ekklesiasterion exercise (zip format)

Further video tutorials if needed:

• Introduction to Sketchup and some simple actions (19 min) (Gabriel Bodard)
• Sketchup walkthrough of building (9 min) (Alicia Walsh)
• Sketchup walkthrough of building roof (4 min) (Alicia Walsh)
• Sketchup walkthrough of texturing (4 min) (Alicia Walsh)
• Sketchup walkthrough of importing objects (4 min) (Alicia Walsh)
• Alternative, longer tutorial at SunoikisisDC 2019 (starts at 53:06) (Valeria Vitale)
• Full walkthrough of Ekklesiasterion exercise in Sketchup Make 2017 (42 min) (Coré Ferrer-Alcantud)

Optional exercise

If you completed the practice above, you may like to try modelling another building without such a detailed walkthrough. You will need to find floor-plans, dimensions and preferably photographs in the archaeological literature. If you prefer, you may find some building plans in the two publications herebelow:

1. Mycaenean Tomb beneath the Middle Stoa; see especially Figure 1 and Plate 1a as the basis for your model.
2. Roman Villa Gardens pick any of the figures, depending on how ambitious you want to be! (3.2, 3.5, 3.11 may be at the more manageable end of the scale.)
