Pléascach is the irish word for "explosive", which felt like a cool, and fitting name for my first foray into writing a rendering (and god willing, game) engine. So far it's sitting pretty at about ~3k SLOC in this latest (as of Feb. 21, 2024), and is capable of loading (but not yet shading or texturing) a HL1 bsp, generating variably-tesselated terrain from a heightmap, loading glTF models, and also has a raymarching branch. More to follow.
