SDF · Union
Boolean union of two SDFs with an optional smooth polynomial blend:
d(p) = smin(a(p), b(p), k)where k is the smoothness parameter. k = 0 gives a sharp boolean; larger values blend the two fields with a polynomial smin (Inigo Quilez).

Sockets
a (in)- SDF. Required.
b (in)- SDF. Required.
smoothness (in)- Float. Optional override for the blend radius.
sdf (out)- SDF — union of A and B.
Parameters
Smoothness- Polynomial blend radius in world units. 0 = sharp (hard min), positive values round the transition. Default: 0.
