1. Overview of Babylon.js LT meetup
As you know, there is a Babylon.js community in Japan as "Babylon.js Japan".

2.1 Let's use open data with Babylon.js! - Toyohashi city -

- He already tried to make digital twin with Babylon.js. (See his past book)
Babylon.js レシピ集 Vol.2 (Only Japanese version)
This trial shows rainy perscent data on map. He showed the percent as three-dimensional graph shape with Babylon.js

- His blog in JP:
2.2 Make Babylon.js with C# ~ "BabylonCS" ~
Presenter："にー兄さん" (ni-ni-san) @_ninisan_drumath

His recent interest was how to implement Babylon.js as C#.

『軽率にBabylon.jsをC#で使う技術』！
マジで #BabylonJS が C# で動いててヤバい(語彙力)
[デモ内容]
C# のコード、実行して、いつものスフィアが出てくる。
そこを 1行 box に変更して再実行すると
ちゃんと box に！

Motivation
Some beginners who started Babylon.js had their Unity/Unreal Engine experience.
- It is not easy for them to use JavaScript.
If they can use C#, more developers can use Babylon.js.
His current work is on GitHub. Stay tuned his further updates.

WebAssembly(WASM) : A method that source codes except for JS can work on browsers.

2.3 A concept that an animation is showed on Babylon.js
Presenter：ricky @N1809031125
- His motivation to use Babylon.js : He can easily check implementating results.
- His goal : Making animation on Blender, synchronizing them on Babylon.js at real time.
- First trial : Made an animation on Blender and recorded as mp4 format. Playback the file on Babylon.js and confirmed the concept.

『アニメーションをBabylon.jsで表示させてみた』
Blender と Babylon.js の相性良さそうだね☺️
あと「全部 VR 空間で解決させたい」みたいな話も、とてもわかりみがある…！👏#BabylonJS勉強会 #BabylonJS pic.twitter.com/nczDD22mio
2.4 I'd like to do real time geek activities for virtual idols on Babylon.js
Presenter：hiroyoshi-muranaka (@mononanokamo)
Presentation slides:
https://www.canva.com/design/DAF6wJo1vLg/2UnacmR5QsnSxACMbYEyKA/edit
- The presenter was a first grade student on a high school.
- His works: A virtual character as VRM format danced with a good music. Several client devices can show her dance at the same timing.
- We can check the demo movie on P.3 of his presentation slides (If you don't know Japanese, don't worry!)
- Why did he developed it on Babylon.js? : He could easily make WebXR contents. It was easy for him to use it because he knew JS and Web technologies.
- "Songle API", which was developed by AIST, was main component of his works. The API could manage and synchronize timing on each devices.

2.6 Let's write books!
Final part was me. As you know the community had three books for technical showcase events.
Next event will be held on March. I appealed the activities for listeners.
3. Conclusion
As shown in the community page, over 540 members attended the community!
Stay tuned our further activities from Japan! Next will be held around release date of Babylon.js 7.0!
