### Segment 1 (00:00 - 02:00) []

dear fellow Scholars this is 2minute papers with Caro have a look at this magnificent idea the input is a digital 3D model of an object and the Viewpoint of our choice and the output is an easy to follow step-by-step breakdown on how to draw it automated Drawing Tutorials I wish tools like this were available back when I was a child awesome this technique offers a way to create the scaffoldings to help achieving the correct perspective and positioning for the individual elements of the 3D model something that novice artists often struggle with this problem is particularly challenging because we have a bunch of competing Solutions and we have to decide which one should be presented to the user to achieve this we have to include a sound mathematical description of how easy a drawing process is the algorithm also makes adjustments to the individual parts of the model to make them easier to draw without introducing severe distortion to the shapes the proposed technique uses graph Theory to find a suitable ordering of the drawing steps beyond the scientific Parts there are a lot of usability issues to be taken into consideration for instance the algorithm should notify the user when a given guide is not to be used anymore and can be safely erased novice apprentice and adapt users are also to be handled differently to show the validity of this solution the authors made a user study where they tested this new tutorial type against the most common existing solution and found that the users were not only able to create more accurate drawings with it but they were also enjoying the process more I commend the authors for taking into consideration the overall experience of the drawing process which is an incredibly important factor if the user enjoyed the process he'll surely come back for more and of course the more we show up the more we learn some of these tutorials are available on the website of the authors as always I've linked it in the video description if you're in the mood to draw make sure to give it a go and let us know how it went in the comment section hell even I am now in the mood to give this a try if I disappear for a while you know where I am thanks for watching and for your generous support and I'll see you next time oh
