Documentation / Example for materials about webgl-obj-loader HOT 3 OPEN

Thanks! In the past couple days, after bouncing around the web- I eventually landed on glTF... seems like I'm going to be putting my energy more into trying to make that work as opposed to Obj parsing... but I have a lot to learn and your repo is one of the rare resources out there to learn from!

Thank you for your comments!

gltf is a very nice format for many reasons, one of them being that it has standardized its material parameters around a metallic/roughness PBR workflow. As a warning, your linked articles from webglfundamentals.org cover a blinn-phong shading model, which means you'll either need to do some conversion or learn from a different resource.

The cook-torrance paper has all the details, but it's not exactly easy reading. There are some really good notes from epic too.

Thanks for making this issue! It's always encouraging to see people using this library.

You're absolutely correct that the documentation is (severely) lacking for MTL support. We have been trying to add support for MTL's in phases with the actual code being the bulk of the support and the documentation is a part of the last phase. Part of my goal for the documentation is to convert the single README to a full suite of documentation including API specifics as well as tutorials/examples of how to use each component of this library.

As you can imagine, performing such a task requires a lot of time and I haven't had much to be able to devote to this library lately (at least, not since the implementation of the MTL support). However, this issue is a great reminder of the importance of this library for beginners to WebGL, so I will try my best to bump the priority of the webgl-obj-loader and add documentation soon.
