3D Printing With Filigree Patterns | Two Minute Papers #89


Dear Fellow Scholars, this is Two Minute Papers
with Károly Zsolnai-Fehér. Filigrees are detailed, thin patterns typically
found in jewelry, fabrics and ornaments, and as you may imagine, crafting such motifs on
objects is incredibly laborious. This project is about leaving out the craftsmen
from the equation by choosing a set of target filigree patterns and creating a complex shape
out of them that can be easily 3D printed. The challenge lies in grouping and packing
up these patterns to fill a surface evenly. We start out with a base model with a poor
structure, which is not completely random, but as you can see, is quite a forlorn effort. In several subsequent steps, we try to adjust
the positions and shapes of the filigree elements to achieve more pleasing results. The more pleasing results we define as one
that minimizes the amount of overlapping, and maximizes the connectivity of the final
shape. Sounds like an optimization problem from earlier. And, that is exactly what it is. Really cool, right? The optimization procedure itself is far from
trivial, and the paper discusses possible challenges and their solutions in detail. For instance, the fact that we can also add
control fields to describe our vision regarding the size and orientation of the filigree patterns
is an additional burden that the optimizer has to deal with. We can also specify the ratio of the different
input filigree elements that we’d like to see added to the model. The results are compared to previous work,
and the difference speaks for itself. However, it’s important to point out that
even this thing that we call previous work was still published this year. Talk about rapid progress in research! Absolutely phenomenal work. The evaluation and the execution of the solution,
as described in the paper is also second to none. Make sure to have a look. And thank so much for taking the time to comment
on our earlier video about the complexity of the series. I’d like to assure you we read every single
comment and found a ton of super helpful feedback there. It seems to me that a vast majority of you
agree that a simple overlay text does the job, and while it is there, it’s even better
to make it clickable so it leads to a video that explains the concept in a bit more detail
for the more curious minds out there. I’ll try to make sure that everything is available
in mobile as well. You Fellow Scholars are the best and thanks
so much for everyone for leaving a comment. Also, please let me know in the comments section
if you have found this episode to be understandable or if there were any terms that you’ve never
heard of. If everything was in order, that’s also valuable
information, so make sure to leave a comment. Thanks for watching, and for your generous
support, and I’ll see you next time!

  • all good i shall say, maybe don't put white text on a light grey background with a white video behind, but the rest was ok

  • I love this content. Super easy to understand. I never went to college, and work in event management/customer service, so this really isn't my wheelhouse, but your way of explaining things leaves very little to be desired. Keep up the awesome work.

  • Very nice episode, understood as always. As a sub who was there when you only had a few videos i am happy to see you stay true to your form

  • Everything was really easy to follow, however, if you want critical feedback I would say you need to take on the challenge of describing more details from the paper in layman's terms. I understand that is difficult, however, it will lead to significant growth in your audience because people who learn new concepts from a video are more likely to forward that video to friends.

  • Minor thing with the annotations: Instead of having the annotations have a dark semi-transparent background over the text you embed in the video, could you put the semi-transparent background into the video behind the text (to distinguish it better from the background footage – note especially the word "Optimization" is a bit hard to read with that black filigree pattern behind it) and meanwhile make the annotations themselves completely transparent?

    Once again a really nice video covering a really nice paper 🙂

  • The reference at the bottom in white text on semi transparent grey was hard to read, and unclickable as it was under the YouTube pop up controls in my browser. moving the box to the top right of the screen as a one liner and more opaque background would help. Love the format, keep up the good work.

  • When I saw "Chen", I thought for sure it was from a professor here at Texas A&M, Janier Chen (http://faculty.cs.tamu.edu/chen/), because his work is similar. Disappointed it was not some of his work, but still cool.

  • Thank you for these videos. I watch all of them, and they're among the best videos I'm subscribed to on youtube. Much appreciated.

  • I might not have understood every term perfectly, but I understood fairly well, and just hearing about this stuff is fun. 🙂

  • I used Freeform so far, fills 4sided networks with tiling pictures to shoot it in the model. Yojr approach would revolutionise the edging for automotive interior dashboard molds… using 3d milling instead of unpredictable edging. Oh…. and jewelrys cool as well…

  • all the time there is a video to a topic I am interested in. And almost everytime YOU make one of the best structured, best narrated, best explained videos.

    In a perfect world, people like you would be rich and have influence in politics, religion, etc.
