geo/SDFExtrude
Extrudes a 2D SDF field into a 3D one along Z.
Sdf Operations
Thickens each input 2D SDF object along the Z axis into a 3D field, symmetric about the XY plane: the profile sits mid-height. This is the same axis geo/M2DExtrude uses. The result raymarches like any 3D SDF and composes with other 3D SDF objects. The distance is exact wherever the 2D field is exact. Only 2D SDF inputs are accepted; non-SDF objects pass through unchanged.
Parameters
| Name | Type | What it does |
|---|---|---|
| height | Float | Total Z extent of the extrusion, centered on the plane. |
