Class BimGeometricFeaturesRepository

constructor

• new BimGeometricFeaturesRepository(
      _bimApi?: BimCoreApiClient,
  ): BimGeometricFeaturesRepository

  Parameters

  • Optional_bimApi: BimCoreApiClient

  Returns BimGeometricFeaturesRepository

Readonly_geometricFeaturesReader

Readonly_isGeometricFeaturesUrlAdded

assignGeometricFeaturesToProducts

• assignGeometricFeaturesToProducts(geometricFeaturesUrl: URL): Promise<boolean>

  Parameters

  • geometricFeaturesUrl: URL

  Returns Promise<boolean>

clear

• clear(): void

  Returns void

populateFromVertexDataRepository

• populateFromVertexDataRepository(
      products: readonly BimIfcObject[],
      vertexDataRepository: BimVertexDataRepository,
  ): void

  Populate the repository by reading edge indices out of the t8gd buffer managed by the vertex data repository. Edges in t8gd reference the position-deduplicated vertex array — the same array exposed by BimVertexDataRepository.get for V2 format — so the indices match the positions used at render time.

  Use this in place of assignGeometricFeaturesToProducts whenever the geometry resource is .t8gd. The .geom-feat file's edge indices are in the welded-vertex space which does NOT match the t8gd deduplicated layout.

  Parameters

  • products: readonly BimIfcObject[]
  • vertexDataRepository: BimVertexDataRepository

  Returns void

resolveEdgesForMesh

• resolveEdgesForMesh(mesh: BimProductMesh): undefined | FlatSegment3[]

  Resolve feature edges for a single mesh on demand. Looks up the mesh's geometry hash in the decoded feature data, resolves vertex indices to world-space coordinates, and caches the result on the mesh as FlatSegment3 tuples — the format consumed directly by CreateGreasedLine.

  Returns the edges, or undefined if no feature data exists for this mesh.

  Parameters

  • mesh: BimProductMesh

  Returns undefined | FlatSegment3[]

setDecodedFeatures

• setDecodedFeatures(hash: string, features: DecodedGeometricFeatures): void

  Inject pre-decoded feature data for a mesh hash (used by the T8 loader which reads edges from t8gd).

  Parameters

  • hash: string
  • features: DecodedGeometricFeatures

  Returns void
