My name is Kai Kostack, I'm 3D generalist from Berlin specialized in destruction physics. On this channel you'll find:

- Physics based art
- Scientific simulations & visualizations

Most videos are made purely with open source software such as Blender and Gimp.

Over the years I had some influential help that I would like to mention:

Martin Felke - Blender coder who wrote the tool known as Fracture Modifier (FM) a lot of my videos made use of.

Dipl. Arch. ETH Oliver Walter - Research partner for the Bullet Constraints Builder (BCB) software and related videos.

Contraflex put together a detailed look at the 1 km Jeddah Tower, using our simulation software for structural and destruction analyses. If you want to learn more about building structures, this excellent video covers a lot of different topics.

The same WTC shot can survive in a dozen versions – each shaped by copies and compression. Only by comparing them can the clearest originals be uncovered.

Some people have seen it; it was public briefly, but I'm still bothered by a small mistake. I'll have to update tomorrow. The video will remain online for members until then. Please don't share it yet. Sorry for the inconvenience.

The WTC collapse simulation comes with original audio generated directly from the simulation data — not stock Foley. The sounds are synthesized from the motions, accelerations and collision events of thousands of fragments.

A quick share: LiTU – Living in the Universe, an indie sci-fi film by my colleague Fergus, is now available on Amazon Prime UK.
The film was mostly made using Blender and includes a few scenes I contributed. It now has also a Spanish voice-over and English subtitles – German and Italian voice-overs were promised for the future, but don’t seem to be available yet.

Interesting! This video showcases how RFEM 6 and our Bullet Constraints Builder Add-On for Blender can be used to visualize building collapses based on real physical data, emphasizing the importance of open BIM for cross-software collaboration.
