The Drawing part (Mouse events, drawing walls, showing angles between lines etc) on 2D mode is amazing. Any idea whether this 2D mode is also implemented using BabylonJS or it is implemented using some other library?
Why I am asking is, I don’t see any such kind of samples on Babylon.
I don’t understand the question. It is Wanadev that implemented WebGL and chose Babylon.js as the WebGL framework. And there are two integration.js file which are easily read if you want to spend a few hours on the specifics.
I am, however, impressed by the time they spent writing all this code… and very well also.
