Docs directory: Here is Three.js's help document, which is the API for each function, but it is not explained in detail. It is impossible to try to use these documents to learn three.js.
Editor Directory: A simple editing program like 3d-max that can create three-dimensional objects.
Examples directory: Some very interesting examples of demo, unfortunately no documentation. Students who do not understand the image, the cost of learning is very high.
SRC Directory: Source code directory, inside is all source code.
Test directory: Some testing code, basically useless.
Utils Directory: A tool directory that holds some scripts, python files. For example, convert a 3d-max format model to a three.js-specific JSON model.
. gitignore file: The filter rules file for Git tools is not used.
CONTRIBUTING.MD file: An explanatory document on how to report a bug and how to get help.
