Commercial 3D repositories

I submitted a journal article comparing 3D repositories and explaining their features. A reviewer suggested to include a list of 3D commercial repositories. So, I followed his/her advice and made a list of 60 commercial repos. Here is the copy of the table 🙂

While making an online survey and making the list, I have found four genres (there might be more, which I am not aware of) –

1. Most of the repos are ‘trading’ platform or ‘marketplace’. People buy and sell 3D models. A seller usually doesn’t need to pay for upload/showcase the models but have to pay certain % of their earning to the service provider. This type of repos is mostly focused on Gaming industries.

2. The second group is focused on 3D printing. Models are sold by both individuals or commercial software developers. Watertight 3D models targeting the printing industry.

3.  3D software developers also showcase their 3D models (made with/by their own software) and allow free downloads. This third type sometimes also allow their software-users to showcase 3D models.

4. Another type of online platform literally doesn’t host 3D models but hosts ‘3D model developers’ to open their online stores. Interesting business model!

By the way, the most interesting point I have noticed that only four of them have their own 3D model viewer; the rest use 2D images to represent/showcase 3D models.

Sketchfab and Cultural Heritage !

#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 !

New paper at Heritage journal

Thanks Professor Erik Champion ( for your support and mentorship.

Paper Title:
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.

Humanities Journal Article of the Year 2019, Curtin University.

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.

Photo to 3D to AR: Free and Easy

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

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.

Sustainability of 3D models-the hidden criticism

Thanks, Prof Erik about your post.

Erik Champion

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…

Head Mounted Display

I have been trying to understand head-mounted displays (#HMD); why they are for, their use? price? etc. From my understanding, first I have made a ‘poster’ and later a short brief video. As I am not a programmer or developer; this video reflects my own experience of using various HMDs, such as #BoboVR, #HTC Vive, Sony #PayStationVR, #FoveVR, #GearVR, #Meta2 and #HoloLens.

Workshop on ‘3D to Mixed Reality: From Regard3D to HoloLens’

I with my PhD student Mafi conducted a workshop at library makerspace, Curtin University, Bentley, WA, Australia. 18 participants attended the event for 2 hours on 23rd November 2018.

Screen Shot 2018-11-23 at 7.42.36 pm

Brief of the workshop:

3D models adopted/generated from image-based modelling techniques are increasingly used in research, shared online, incorporated into digital archives, and developed as assets for 3D games and for Virtual Reality applications. On the other hand, various HMDs (Head-Mounted-Display) offer Mixed Reality experiences; help us to experience and interact with virtual environments and objects via gesture, speech, gaze, touch and movement. This workshop will demonstrate how to make 3D models from photographs with free and open source software (FOSS, Regard3D), how to import a 3D model to a specific Mixed Reality HMD (Microsoft HoloLens), and you will also learn how the HoloLens can interact with the 3D model in mixed reality.
