## Описание

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. Let's see what this piece of work has to say about the problem!

equation by choosing a set of Target filigre 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 the 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 forar 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 filigre 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 you so much for taking the time to comment on our earlier video about the complexity of the series I'd like to assure you that we read every single comment and found a ton of super helpful feedback there it seems to me that the 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 try to make sure that every everything is available in Mobile as well you fellow Scholars are the best and thank you so much for everyone for leaving a comment also please let me know in the comment 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 see you next time oh
