Tells where each point sits between two shapes: −1 on and inside a, +1 on and inside b, with a smooth ramp across the gap, computed as (a − b) / (|a| + |b|). Use it to drive a morph or a graded change from one shape to the other.
First shape's distance field; the result is −1 on its surface.
Second shape's distance field; the result is +1 on its surface.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
The field read as a Solid whose surface is where the field is zero.
The box the field is evaluated in.
The field with its sign flipped (−f), which swaps inside and outside.
The field divided by its gradient length (f/|∇f|) so it reads close to a true distance; the zero set does not move.
