Why Is My Model Slow? Precision, Bounds, Engines
A diagnostic path for slow Rig Cad projects: find the node, match the symptom, learn the cube law behind SDF precision, and pick engine and GPU settings.
Signed Distance Fields: Geometry as a Function
From exact primitives and Boolean composition to sphere tracing and level sets, signed distance fields turn geometry into a queryable scalar function.
Gyroid TPMS: When Geometry Becomes Structure
From butterfly-wing photonic crystals to compact heat exchangers, the gyroid shows how triply periodic minimal surfaces become tunable engineering structures.
