Overview

Runtime registries for operation providers: MeshBooleanRegistry, MeshPlaneSectionRegistry, MeshHiddenLinesRegistry, MeshVisibleFacesRegistry (behind the mesh-hidden-lines feature) and PointcloudReconstructionRegistry, each behind its own feature. A registry owns provider ordering, device matching, fallback to the next provider, and memory-budget admission. It defines no request or result types: those live in the operation-contract crates, and providers implement them without depending on this crate. The parallel feature scopes each dispatched call to a caller-owned CPU pool.

Features

Default: none.

Changes

Latest release, 0.3.13 (2026-11-13):

Added

• MeshHiddenLinesRegistry and MeshVisibleFacesRegistry route by supports_projection: a provider that does not support the view's projection is skipped, and a request no provider supports is Unsupported before the topology audit. A perspective view needs a near below zero (InvalidInput otherwise). register_perspective_conformant registers a provider after the base suite and the perspective suite. register_conformant of both registries also runs the perspective suite when the provider claims perspective, so an unverified claim is refused (ADR 0107, #387).
• MeshVisibleFacesRegistry accepts FaceGroups::Planar: it checks that a region's group id is a triangle of the mesh and no later than any triangle the region lists, and does not recompute the groups (ADR 0106, #384).
• MeshHiddenLinesRegistry accepts EdgeKind::GroupBoundary segments only when EdgeSelection::group_boundary is set, and then refuses a PerTriangle group slice of the wrong length naming the mesh (ADR 0106, #385).
