geo/SDFBuilder
Defines a signed-distance field from the code nodes inside it.
Sdf Operations
Dive inside and build the field with code/SDF* primitives and operators, wired into code/Output's distance input. The output object carries the field as SDF geometry: wire it to the geo/Output node to see it raymarched, or compose it with other SDF objects. The bounds params declare where the surface lives; keep them generous enough to contain it.
Parameters
| Name | Type | What it does |
|---|---|---|
| size | Vector3 | Local-space size of the box the field's surface fits inside. |
| center | Vector3 | Local-space center of the bounds box. |
