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.
… In SDF 3D modeling, there’s real-time blending and real-time Boolean operations (addition, subtraction, intersection…) between primitive shapes, as well as filleting and chamfering without the possible issues when using polygons or NURBS.
Colors can be blended non-destructively into the SDF 3D models as well. Once you’re done creating, the result can be meshed and exported if desired.
