Geometry Nodes, Displacement, and the Implicit Tree
If you already think in Geometry Nodes, the Objects tree is the graph. Mesh Boolean is a hard CSG node. The purple diamond turns that same node into a field.

From exact primitives and Boolean composition to sphere tracing, level-set motion, and neural fields, signed distance fields turn geometry into a queryable scalar function.
