Over the last few months in the National Museum of Archaeology, Valletta, Malta, there has been an exhibition of the FRAGSUS project (https://www.qub.ac.uk/sites/FRAGSUS/). This has been an exceptional project I have been working on over the years, and as part of the exhibition I got to display some of the 3D reconstructions I have made of Maltese structures, mainly the Ghajnsielem Road house and the Xaghra Circle.
The models I made were displayed as fly-through animations, which I made using the V-ray plugin for Sketchup. Looking back at the videos I made, I noticed that I was mainly using three types of shots:
These are fairly typical shots which can be found in many museum exhibitions and online (Sanders and Sanders 1998; Hixon et al. 2000). It is also reminiscent of online viewers such as Sketchfab.
Now, I am a big movie fan. I am currently going through the 1001 Movies to Watch Before You Die list and I am really enjoying studying the cinematography of some of the films. The way lighting is set up, or the tinting of the scene and the movement of the camera, are all elements that for me make a good film and provide an intense entertainment experience.
The aim of film and of 3D reconstruction animation is very similar: they are both presenting some kind of narrative to the public. The way films portray narrative and create aesthetically pleasing experiences is by using tools that could easily be imported into 3D reconstructions. So why not create more cinematic renders of 3D models for archaeological exhibitions?
Here is a new render of the site:
The shot is done with high coloration, camera blur, faster shots and forced depth of field. I took inspiration from these Wes Anderson shots:
The Royal Tenenbaums (2001)
Moonrise Kingdom (2012)
Moonrise Kingdom (2012)
The Darjeeling Limited (2007)
The use of less conventional rendering techniques can impact knowledge retention in the user. The perceived “warmness” of the cinematic experience increases the feeling of immersion, which can lead to increased learning (Favro 2012). Although the images are hyperrealistic, they will be familiar to the viewers as they belong to a medium that is commonly used.
On the subject of accuracy, it is important to note that the realer the images seem, the more they may be mistaken for “absolute truth” (Eiteljorg 1995, 1998, 2000; Miller and Richards 1995; Gershon 1998 and many others). This is an inherent issue in all 3D reconstructions, but that I would argue is a deeper problem for all of archaeology: the very museum displays in which the 3D reconstructions are presented often follow a single narrative, while ignoring evidence against it or alternative theories. While it is therefore vital to ensure the correct information is accessible by the end user, it would be impossible to convey the complexity of a 3D reconstruction in a museum setting.
As a wider argument for 3D reconstruction as presentation, I would propose that the finished render should have the liberty to display freely aesthetically pleasing imagery, even to the loss of accuracy. This is possible so long as the model is verified through careful research that is accessible and (when possible) peer reviewed. This would ensure a level of quality in the final render that takes into account inaccuracies but doesn’t limit the user enjoyment.
A much longer discussion on the accuracy in 3D reconstruction is the subject of my current PhD Thesis, but I would suggest reading Sifniotis, M. (2012), which proposes a scientific method of dealing with inaccuracies.
In conclusion, 3D reconstruction animation doesn’t have to be boring or “cold”. Rendering of 3D models can learn a lot from films when it comes to presenting to the general public. By creating aesthetically pleasing content, user enjoyment and learning become the priority.
