Nuclear Wasteland

I learn about the idea of nuclear semiotics a while ago and wanted to depict a desolate wasteland where the only things remaining are the attempts of a prior civilization to warn against what’s buried underground. I had a lot of ideas for this project (more stuff, raytraces shadows etc) but had to cut it quite short due to the exam timeline :(

Features

This is project is entirely implemented in one fragment shader “showcase.fs”. The features include: Terrain: perlin noise accumulated with fractional brownian motion sculpting the terrain using smoothstep and smooth heaviside functions

Spikes:
    Using an sdf with its normals to form spikes
    domain repetition to give the effect of many spikes with random perturbations

Sky:
    just more fbm
