    Project mention: Doing the math. Please help | reddit.com/r/GraphicsProgramming | 2021-06-25

    One thing http://www.kmjn.org/notes/3d_rendering_intro.html does not mention is how you get the "list of triangles" it refers to in the "Wireframe rendering pseudocode" section. For that, you need to write or find an existing a library that can read in your 3D object data files (e.g. Wavefront OBJ files, STL files, or what have you). Assimp is one such library, but writing a simple STL file importer yourself is not super hard.
