#Sketchfab is a platform to store, publish, share, buy/sell and visualise 3D model (in AR/VR). It provides a ‘viewer’ that allows users to display/view #3Dmodels on the web, mobile device, #VR headset and in #AugmentedReality (through provided app). The viewer also allows 3D animations, annotation of text and images and embedding 3D model on external websites on #Facebook, #Twitter and #WordPress. The most interesting thing is, they support cultural heritage institutes for hosting and sharing their #digitalassets ! That’s why I love #Sketchfab. Can’t find a suitable rival !

To 3D or Not 3D: Choosing a Photogrammetry Workflow for Cultural Heritage Groups
The 3D reconstruction of real-world heritage objects using either a laser scanner or 3D modelling software is typically expensive and requires a high level of expertise. Image-based 3D modelling software, on the other hand, offers a cheaper alternative, which can handle this task with relative ease. There also exists free and open source (FOSS) software, with the potential to deliver quality data for heritage documentation purposes. However, contemporary academic discourse seldom presents survey-based feature lists or a critical inspection of potential production pipelines, nor typically provides direction and guidance for non-experts who are interested in learning, developing and sharing 3D content on a restricted budget. To address the above issues, a set of FOSS were studied based on their offered features, workflow, 3D processing time and accuracy. Two datasets have been used to compare and evaluate the FOSS applications based on the point clouds they produced. The average deviation to ground truth data produced by a commercial software application (#Metashape, formerly called #PhotoScan) was used and measured with #CloudCompare software. 3D reconstructions generated from FOSS produce promising results, with significant accuracy, and are easy to use. We believe this investigation will help non-expert users to understand the photogrammetry and select the most suitable software for producing image-based 3D models at low cost for visualisation and presentation purposes.

We may be well aware of ‘Heritage Interpretation’ and the role of ‘Interpreter’. However, is there something called ‘Digital Heritage Interpretation’? When we use a mobile app and visit/explore a heritage site, can we refer that ‘app’ as an ‘interpreter’? If yes, then what should the app need to do/present/communicate with us to achieve the best understanding of the site.
Curtin University awarded me ‘Humanities Journal Article of the Year 2019’ for my paper ‘Digital heritage interpretation: a conceptual framework’ that tries to answer these questions.

I have published an online #videotutorial (or course) on “Photo to 3D to AR: Free and Easy”. This course is designed for beginner to intermediate user, to show the process of creating detailed and accurate 3D models with texture using #Photogrammetry. Keeping in mind following this method, the users can save a large amount of time in 3D modelling with compare to manual modelling and texturing. I offered the course at #Udemy and it is completely FREE at https://www.udemy.com/photo-to-3d-to-ar-free-and-easy/
I spent a large amount of my spare time for planning, recording and in developing the course, and offered it as Free. Wondering, whether it could help others to learn #photogrammetry. I am surprised to see within 10 days, more than 1900 students across the world got enrolled !!! Also surprised, that two HOD from #CurtinUniversity have shown their interest to include this course under formal university modules.

Thanks, Prof Erik about your post.
I mentioned last month Hafizur and I had an open access journal article out, “3D Digital Heritage Models as Sustainable Scholarly Resources” at MDPI Sustainability journal.
Champion, E.; Rahaman, H. 3D Digital Heritage Models as Sustainable Scholarly Resources. Sustainability2019, 11, 2425.
We were invited at very short notice to write this article, with a strict word limit, but a month before the invitation we had an earlier, sort of similar article reviewed very critically (apparently) by the first reviewer of another journal. Rather than wait for review 2 we pulled that article. So this article was built on the ruins of that article. However I never saw the reviewer 1 comments!
I write this as this article has been very well received (and downloaded) so far (well in 3 or so weeks). If there are negative comments out there I am happy to hear them…
