Many thanks for the Js graphic library, this is usefull for many projects in 3d application development.
I would like to know can i use the library for commercial industry, is this open source?
It’s a standard MIT license, which basically means you can do anything you like with the software, including using it in commercial products, except claim that you wrote it.
If you’re looking for more info, search for ‘using MIT licensed opens source software in commercial products’.
