Geometry & 3D node
Geometry Slice
Cuts the mesh with a plane and keeps one side, clipping crossing triangles exactly at the cut. The plane faces along Axis, tilted by the two Angles, and slides along its normal with Offset — cable an LFO into Offset and the shape grows out of nothing, the classic reveal. Flip keeps the other side; Cap seals the cut with a flat fill (exact for convex cross-sections, approximate for wilder ones).
Inputs
| Port | Type | Default |
|---|---|---|
| GeometryThe mesh to cut. Triangles crossing the plane are clipped exactly at it. | structure | — |
| AxisThe base direction the cutting plane faces before the Angle tilts. | int | 1 |
| Angle XTilts the cutting plane around X, degrees. | float | 0 |
| Angle YTilts the cutting plane around Y, degrees. | float | 0 |
| OffsetSlides the plane along its normal. Cable an LFO here for the classic grow-out-of-nothing reveal. | float | 0 |
| FlipKeeps the other side of the cut instead. | bool | false |
| CapSeals the cut with a flat fill — exact for convex cross-sections, approximate for wilder ones. Off leaves the cut open, showing the hollow inside. | bool | true |

How It Works
Geometry Slice cuts the mesh with a plane and keeps one side, clipping crossing triangles exactly at the cut rather than dropping whole triangles.
The plane faces along Axis, is tilted by the Angles, and slides along its own normal with Offset — cable an LFO into Offset and the shape grows out of nothing, which is the classic reveal. Flip keeps the other side. Cap seals the cut with a flat fill: exact for convex cross-sections, approximate for wilder ones.
Use Cases
- Reveals — Animate Offset and the object builds itself.
- Cross-sections — Cut a model in half to show its interior.
- Half shapes — A hemisphere from a sphere, a trough from a cylinder.
- Clipping to a stage — Slice away everything below the floor plane.
- Composition — Cut a shape at an angle for a deliberate flat face.
Tips
- Cap works best on convex cross-sections; on a shape with holes the fill is an approximation.
- Chain two Slices with opposite Flips to keep a slab between two planes.
- Slice before Shell if you want the cut to have thickness.
- Animating Offset is cheap — the mesh is re-clipped, not rebuilt from the source parameters.
