Intermact API Reference / @intermact/core / GeometryProvider3D

Interface: GeometryProvider3D

Defined in: packages/core/src/object/geometry-provider.ts:111

3D geometry provider (design.md §5.3). Like GeometryProvider2D, it answers "how is this sampled / bounded". A provider exposes exactly one of the line / mesh / points channels (advertised via kind); the renderer dispatches on kind.
