"WebbAs you combine more primitives together, you can make more complex shapes. In some of the later examples, the "scenes" are built by unioning multiple shapes together (even when they're not touching each other) before calling them from the raymarching function. In the OP, the shapes are defined within the map functions. " - Shapes with raymarching research
