3D Tessellation - Tetrahedron Octahedron Honeycomb

[CV98]

Hello! Im newer to programming. I do not have the skills to accomplish what I am aiming to do. What I would like to do is create a "Tetrahedron Octahedron honeycomb" with OpenGL. I really don't even know where to start. I've started creating the core of my game engine but it is very tedious and unmotivating. If someone could push me in the right direction to make a 3D Tessellation similar to Perlin Noise with Cubes but I want to use Octahedrons and tetrahedrons. Thanks in advance!

Tried checking out Geometry Shaders?

I know what you are trying to get at but what Im trying to create is a generation of tetrahedron objects and octahedrons object. Objects being .obj files.

If you know the geometric shape you're shooting for, try banging out the method for generating it on paper. I only recommended the geometry shader because it could be leveraged to generate it quickly, much more quickly than you could on your CPU.

Creating this seems odd for a game engine, or at least very use-case specific. Why not create a renderer than can read from pre-made .obj files and render them?
