geo/SDFMirror
Mirrors an SDF object about three axis planes through a point.
Sdf Operations
Folds each input SDF object across the chosen axis planes, all of which pass through center. Only the part of the object on the positive side of a mirrored axis survives: it is what gets copied to the other side, and anything living only on the negative side disappears. A 2D field ignores the Z toggle and center's z, since its samples never leave the plane. Non-SDF objects pass through unchanged.
The fold is one node with no boolean and no duplicated subtree, which is what separates it from geo/Mirror. That node REFLECTS across one arbitrary plane and, with keepInput, emits both halves as two objects. The two agree only when the input lies entirely on the positive side of the fold.
Parameters
| Name | Type | What it does |
|---|---|---|
| mirrorX | Bool | Reflect across the YZ plane (x = center.x). |
| mirrorY | Bool | Reflect across the XZ plane (y = center.y). |
| mirrorZ | Bool | Reflect across the XY plane (z = center.z). Ignored by a 2D field. |
| center | Vector3 | The point all three fold planes pass through. A 2D field reads x and y and ignores z. |
