3D Modelling Tutorial

Hi everyone,

I’ve been meaning to post new articles to this website but have been distracted by PhD writing (hoping for a September hand in).

However, given the current situation I thought that this would be a good occasion to organise a free online tutorial for 3D modelling. I regularly get contacted by readers asking for advice on how to start modelling so I am happy to put some time aside each week to go through the basics.

If this sounds like something you would be interested in, please drop me an email at robbarratt1@outlook.com. It would be good to determine if there is actual interest before planning anything, and I would love some suggestions on topics that people would like to explore. I can discuss anything from modelling in Sketchup, to Unity, coding, 3D simulations and 3D theory. I’m not too hot on photogrammetry anymore so anything beyond basics may be difficult, but anything else is good.

Alternatively, if you just want to chat about 3D stuff, drop me an email anyway.

Cheers and stay safe!



Community Engagement and Online Galleries

One of the main aims of the 2013 excavation at Caerau was to engage the community as much as possible, so that this amazing hill fort would become part of the people living in Cardiff and particularly Ely, rather than something separate from them. During the four weeks spent on site hundreds of school children were shown around the site and asked to perform tasks such as writing letters to the Iron Age, washing finds and making pottery.

In particular the kids were asked to make some “celtic heads” using clay, basically faces decorated in any way they liked. The results are extremely artistic and are worthy of being put on display, something which I realised may be possible to do using Photogrammetry.

Hence having selected 40 or so of the most well preserved heads (some had cracked due to the sun) I proceeded to 3D them and the results can be found at http://robbarratt.sketchfab.me/folders/celtic-heads . This way everyone can appreciate the great work these kids put into them.


At the same time this shows another potential for Photogrammetry, which is creating online galleries, potentially entire museum collections stored on the web and accessible to all.
