I've been posting a lot about SDF modeling in #MagicaCSG and #Unbound lately, so I thought to explain a little bit about it…
SDF stands for Signed Distance Fields, falling in the CSG 3D category (Constructive Solid Geometry). 3D SDF is based on volumetric math functions, and offers complete modeling freedom without any concerns about topology / mesh structure, unlike polygonal modeling or even NURBS modeling.
