In this demo a particular optimised specialisation known as sphere tracing is used. Here's how it works: * Given a starting point `p0` and a direction (i.e. a ray) begin by querying the SDF as usual to produce a depth result `r0`. * Next step along the ray from `p0` by a distance of `r0` and query again.
