constructor

  • Create a new node instance.

    Parameters

    • ca: number

      Compass angle. If the SfM computed compass angle exist is should be provided to override the original EXIF compass angle.

    • latLon: ILatLon

      Latitude and longitude in WGS84 datum. If SfM computed latitude and longitude exist they should be provided to override the original EXIF values.

    • worthy: boolean

      Value indicating whether all tiles required to calculate the edges for this node are cached.

    • sequence: Sequence

      The sequence of nodes that this node belongs to.

    • apiNavImIm: IAPINavImIm

      Raw node properties.

    • hs: string[]

      Array of tiles required for calculating edges of this node.

    Returns Node

Accessors

apiNavImIm

ca

  • get ca(): number

  • Get ca.

    Returns number

    Compass angle. If the SfM computed compass angle exist it will be returned, otherwise the original EXIF compass angle.

edges

  • Get edges.

    Returns IEdge[]

    Array of edges to nodes in the graph to which this node can navigate.

edgesCached

  • get edgesCached(): boolean

  • Get edgesCached.

    Returns boolean

    Value indicating whether the edges of this node has been cached.

fullPano

  • get fullPano(): boolean

  • Get fullPano.

    Returns boolean

    Value indicating whether the node is a complete 360 panorama.

hs

  • get hs(): string[]

  • Get hs.

    Returns string[]

    Array of tiles required for calculating edges of this node.

image

  • get image(): HTMLImageElement

key

  • get key(): string

latLon

  • Get latLon.

    Returns ILatLon

    Latitude and longitude in WGS84 datum. If SfM computed latitude and longitude exist they are returned, otherwise the original EXIF values.

loadStatus

loaded

  • get loaded(): boolean

  • Get loaded.

    Returns boolean

    Value indicating whether the node is considered to be fully loaded. To be considered loaded the image has to be loaded and the edges cached.

merged

  • get merged(): boolean

  • Get merged.

    Returns boolean

    Value indicating whether SfM has been run on the node and the node has been merged into a connected component.

mesh

  • Get mesh.

    Returns IMesh

    SfM triangulated mesh of reconstructed atomic 3D points.

pano

  • get pano(): boolean

  • Get pano.

    Returns boolean

    Value indicating whether the node is a panorama. It could be a cropped or full panorama.

sequence

worthy

  • get worthy(): boolean

  • Get worthy.

    Returns boolean

    Value indicating whether all tiles required to calculate the edges for this node are cached.

Methods

Private _cacheImage

  • _cacheImage(): Observable<ILoadStatusObject<HTMLImageElement>>

  • Cache the image.

    Returns Observable<ILoadStatusObject<HTMLImageElement>>

    Observable emitting a load status object every time the load status changes and completes when the image is fully loaded.

Private _cacheMesh

  • _cacheMesh(): Observable<ILoadStatusObject<IMesh>>

  • Cache the mesh.

    Returns Observable<ILoadStatusObject<IMesh>>

    Observable emitting a load status object every time the load status changes and completes when the mesh is fully loaded.

cacheAssets

  • cacheAssets(): Observable<Node>

  • Cache the image and mesh assets.

    Returns Observable<Node>

    Observable emitting this node whenever the load status has changed and when the mesh or image has been fully loaded.

cacheEdges

  • cacheEdges(edges: IEdge[]): void

findNextKeyInSequence

  • findNextKeyInSequence(): string

  • Find the next key in the node sequence with respect to this node.

    Returns string

findPrevKeyInSequence

  • findPrevKeyInSequence(): string

  • Find the previous key in the node sequence with respect to this node.

    Returns string

makeWorthy

  • makeWorthy(): void

  • Make this node worthy.

    description

    The node is considered worthy when all tiles required to calculate the edges for the node are cached.

    Returns void
