Part of this Master’s program entails 3D Modelling as the first step to create a 3D Covid-19 collection on our website using an object of our choice to represent via “Sketchfab” 3D viewer.

3D Modeling in a few words


Structure from Motion (SfM) together with the software Agisoft Metashape Professional were used for our 3D modelling. Computational power was substantial, hence I used an old desktop with a dedicated Graphics Processing Unit (GPU), which sped up parts of the process compared to my laptop. Although the process seemed simple, I can now say with confidence that according to the quality of pictures and the object chosen, it can become quite tense and complicated.

I initially chose to reproduce my ping-pong paddle. After plenty of iterations including capturing, masking, and processing, I realized that even material like the wooden and rubber parts of the paddle would be hard to reproduce. Although powder and drawings to enrich the even surfaces made things easier, there were still parts of the object that were difficult to be processed by the software. After different combinations of images and settings without better results, I switched objects, turning my focus on the “Catan Card Game”. This should have been decided earlier before too much time was spent on the processing of the paddle.

The processing of Catan was easier, as I captured the game in the form of a set card game on a surface. Just like capturing the paddle, markers were placed around the object to facilitate alignment. I captured all the angles of the object, but the artificial lighting at home did not help create the best lighting conditions to avoid all reflections and shadows, even by placing white paper in front of the lamps. The multiple colours, as well as the texture of the box and the cards, were processed in a more accurate way without much effort. I also tried to capture the object on a wooden surface, in order to display the game on the surface. However, the software reproduced only part of this surface, and therefore, I decided to only keep the card game itself.

Thanks to our Professors and my classmates, I managed to do my best throughout the week. After all, cooperation and support are essential to achieve one’s goals.
