CutPlane

One plane of the cut presenter (field-presentation §FVE-9): on or off, an axis, an offset along it, and which half it keeps (scene-tree-row-standard §RSD-3).

In the namespace construct::model::presentation. Declared in src/libs/libconstruct/construct/model/presentation/Presentation.hpp.

Detailed description

The plane is in the item's reference shape (§FVE-3 rule 4). Its normal is +axis, or −axis when flip is set. The kept half is where `dot(p, normal) <= dot(point, normal)`: the shader discards the other half, and the cap faces the discarded half.
