Interface SimplifiedElementMesh

One element simplified by the demesher (GeometryProcessor.simplifyMeshes).

interface SimplifiedElementMesh {
    cavitiesDropped: number;
    expressId: number;
    level: number;
    localIndices: Uint32Array;
    localPositions: Float64Array;
    render: MeshData;
    trisAfter: number;
    trisBefore: number;
}

Properties

cavitiesDropped: number

expressId: number

level: number

Demesher level this result was produced at (1-5).

localIndices: Uint32Array

Triangle indices over localPositions, 0-based, IFC winding.

localPositions: Float64Array

The same vertices in the element's IFC object-placement frame, FILE units, IFC Z-up (xyz triplets) — the tessellated-IFC export payload.

Replacement render mesh (WebGL Y-up, same conventions as pipeline MeshData) — feed to Scene.addMeshes after removing the element's old meshes.

trisAfter: number

trisBefore: number
