Lava World — Procedural Alien Exploration in Apple Metal

A volcanic alien planet, rendered in real time on Apple Metal. Same compute kernel as the desert and ice reels — biome flag set to 2, and the whole scene shifts to ember rock, lava cracks, ash-thick haze, and a smoldering twin-moon sky.

Lava cracks aren't a separate effect. They're an emissive branch in the terrain material function, lit by view-space fbm noise thresholded into glowing veins. The mid-altitude band has fewer cracks; the lowest flats are nearly lakes of lava.

Single Metal compute shader, single Swift driver, single integer switches between desert, ice, lava, and toxic biomes.

Part 3 in a four-biome series — all from the same shader.
