awesome-hpp VS tinyobjloader

awesome-hpp. A curated list of awesome header-only C++ libraries.

I sampled ten arbitrary projects from https://github.com/p-ranav/awesome-hpp, and not one of them used this pattern. Maybe it's more common in some circles than others?

If package managers seem intimidating, try header-only libraries that require no compilation or configuration.

That doesn't mean there aren't any header-only libraries. Usually small libraries implement everything in a header file. Checkout this GitHub link. With such header-only-libraries, all you have to do is include the header, write code which uses them, compile and you are done. This also doesn't involve the headache of setting up complicated build systems.

Obj file parsing isn't really OpenGL... But you can take a look at this GitHub project: https://github.com/tinyobjloader/tinyobjloader

For the Blender export part, the simplest 3D model format is OBJ. It's a text format that can be read in only ~100 lines of code. You can use Assimp for this. Or you can use something like tinyobjloader: https://github.com/tinyobjloader/tinyobjloader

I've replaced tinyobjloader with fast_obj which speeds up model loading process significantly. Here is a good article comparing different obj loaders.

I don't think this is an issue with tinyobjloader but I'm unsure of how to troubleshoot from here. I've been following this tutorial to learn opengl.

Exampes I've seen are the stb single header libraries, as well as tinyobjloader. The necessity to do this is usually written in the comments at the top of the header file:

If you´re using tinyobjloader, the documentation here https://github.com/tinyobjloader/tinyobjloader explains how it works. There´s even a triangulate flag.

Also, it's possible to store a color per vertex, tinyobjloader supports this extended format for OBJ. But, like you say, how many (if any) OBJ loading programs actually support these vertex colors I suspect you can count on one hand (and more likely, zero hands). Blender, for example, does a terrible job even interpreting cutout objects in OBJ files, a common case (see step 9). I doubt they'd ever add per vertex color import support for any file format they read in. But, I'm interested to hear if they do - Blender is (by far, I believe) the main DCC app used with Mineways exports.
