Maybe it’s time to do something with all those 3D city models?

GEO1008 | 2019 Three-dimensional geometries in geoinformation
Hey .. currently i am working as modeller in AutoCAD map3d. Please can you give carrier guidence in gis and gml projects..and by the way i am from india.
7:47 I can't find any established definition/documentation on Chi shapes, where might I learn more? Do they have another name?
This is highly appreciated. Thank you. Kindly which software are you using when drawing the voronoi, triangles and other graphics in your video?
VV Good
Super Sir...Nice Explanation❤❤❤❤
u made it look easy
Brilliant work 💯
Thank you for making this video.. you did a great job in explaining the concept in a easy to understand manner.
Thank you for clearing up the role that the circumcircle plays in Delaunay triangulation.
Beautiful. I really liked the way U explained. ❤
Great quality, to the point and understandable content. But at 14:20, where the diagram updates simultaneously as you added points, and kept switching between Voronoy and Delaunay diagrams, it was hard to concentrate on the content spoken at that time frame. It would really be nice if you could have the speech & complex visualisations separate. This is just a suggestion and hope it’s not misunderstood. 🙂
would you mind if i ask whether than visualizer was a software or a personal piece of code and whether i can have access to it?
it's my own code, in Delphi from 2005. It doesn't really work anymore and I cannot compile it anymore... sorry.
@@HugoLedouxTUD no worries m8 great work again
what kind of software did you use for the creation of the delauney triangulation?
at ~13min I used my own code written in Python. It's not really stable nor fast, just a demo I made for fun. Code is not open-source. But you can try my better code, written in Rust: hugoledoux.github.io/startin_wasm/ Rust code is there: github.com/hugoledoux/startin and its Python bindings: github.com/hugoledoux/startinpy
@@HugoLedouxTUD thank you
Very well explainded, merci!
i am engineer by profesional... next year i planing to further study in intergration BIM and GIS.i very scare do to this because most of what you teach i dont understand... Can you give me some advice on where to start. sepecialy to understand about semantic
Start with gml modelling in AutoCAD
thank you so much !!
Never got bored , really good teaching
Hope to have teacher like you
I don’t remember how I ended watching this video but I’m glad I did, I’ll show it to my urban geography colleagues. I’m keen to import a cityjson file into VR and see what we can do with it. Merci Hugo!
i have watched countless videos and read countless articles on delaunay triangulation and voronoi diagrams and this was the only thing that explained it fully and allowed me to understand it properly. thank you
What a nice and clear explanation
thank you, this video is very informative,
Great explanation!
Thank you for a clear explanation.
How to produce seeds for 3D conical hollow body
nice work ..
1 - Thank you for the brilliant video. 2 - Thank you for the excellent course which you are kindly giving away for free! 3 - Thank you for the book, I haven't found it yet but I see you reference it. Just downloaded your github folder, looking through the online course now; it's so interesting, thank you again.
Kiss ass 🙄
The book is there: github.com/tudelft3d/terrainbook/releases/download/0.8.0/terrainbook.pdf
Hi Hugo. Do you know how to build voronoi diagrams using fast marching ?
Great, thanks for posting!
Prof. Ledoux, in the future will be possible to get all the content of GEO1004 online? Or, for a complete beginner, where I can find source to learn from scratch, from write my own home or neighborhood in cityjson format to publish at cesium? Thanks!
The full content of last year GEO1004 is archived there: 3d.bk.tudelft.nl/courses/backup/geo1004/2020/ And for CityJSON, we have a few tutorials/help there: www.cityjson.org/help/users/
