Got dat fine ass Gouraud shading implemented. Working on Phong. Thought I'd share. Anyone ever toy around with DirectX before? This shit is confusing as fuck, and it's as if DX9 has no documentation.

Code: [Select]

Basically all that code, minus the shader file, which I didn't include, is responsible for making any 3D object you ever see on a screen not look like this:

Aka, giving it color, visible depth, making it sensitive to light, changing how it would reflect light based on what angle you're looking at it, etc... (aka aka ambient + diffuse + specular lighting)
I think that's pretty crazy.

I figured as much but I still can't decipher it

I've spent several hours this week trying to decipher DirectX's gibberish, and I only posted this because I'm way too excited that it's coming together, somewhat.
