Class WWTAwareComponent

This is a helper base class for Vue components that wish to interact with a WWTComponent through the Pinia state management system. It is only recommended for using using Vue’s “options API”. If you are instead using the “composition API”, it is recommended to use engineStore directly.

This class doesn’t implement any special functionality itself. All it does is provide a set of state variables and methods that are pre-connected to the WWT Pinia interface. A component inheriting from this class can use whichever ones it needs without having to set up that integration itself. For that reason, the detailed API associated with this class is intentionally undocumented, so that the in-depth documentation can be centralized in one place: see the API summary associated with the engineStore function.

Example

Say that you are creating a simple WWT-powered app with a main App.vue component that includes a WWT sub-component and a readout of the current coordinates of the WWT view center. Your app Vue file might look like this:

<template>
  <div id="app">
    <WorldWideTelescope wwt-namespace="mywwt"></WorldWideTelescope>
    <p class="coord-overlay">{{ coordText }}</p>
  </div>
</template>

<script lang="ts">
  import { defineComponent } from "vue";
  import { fmtDegLat, fmtHours } from "@wwtelescope/astro";
  import { WWTAwareComponent } from "@wwtelescope/engine-pinia";

  export default App = defineComponent({
    extends: WWTAwareComponent, // <== we are extending WWTAwareComponent

    computed: {
     coordText() {
       // We don't have to define `wwtRARad` and `wwtDecRad` ourselves:
       return `${fmtHours(this.wwtRARad)} ${fmtDegLat(this.wwtDecRad)}`;
     }
    }
  });
</script>

Because this component extends WWTAwareComponent, it automatically has getters for wwtRARad and wwtDecRad that can be used to set up the coordinate readout easily.

Note that the extends option is not recommended (or easily used) in the Composition API, which is why it is recommended to use engineStore directly instead.

    addAnnotation

    addCatalogHipsByName

    • Add a "catalog HiPS" dataset to the current view, by name.

      If the catalog name is not in the engine's registry, the promise rejects.

      Parameters

      • options: AddCatalogHipsByNameOptions

      Returns Promise<Imageset>

    addImageSetLayer

    • Request the creation of a image layer. Either a single FITS or an image set.

      The action resolves to a new ImageSetLayer instance. It’s asynchronous because the requested url has to be downloaded.

      Parameters

      • options: AddImageSetLayerOptions

      Returns Promise<ImageSetLayer>

    addImagesetToRepository

    • Add an imageset directly into the engine's database.

      If an imageset with the same URL has already been loaded, this is a no-op.

      This returns the imageset that ultimately resides in the engine's database. It could either be the input argument, if it was newly added, or a pre-existing imageset in the no-op condition.

      Parameters

      • imgset: Imageset

      Returns Imageset

    applyFitsLayerSettings

    • Alter one or more settings of the specified FITS image layer as specified in the options.

      Parameters

      • options: ApplyFitsLayerSettingsOptions

      Returns void

    applySetting

    applyTableLayerSettings

    • Alter one or more settings of the specified tabular data layers as specified in the options.

      Parameters

      • options: ApplyTableLayerSettingsOptions

      Returns void

    captureFrame

    • Capture the current frame as an image Blob with the desired width, height, and format. The first argument is a callback function to execute on the created Blob.

      Parameters

      • options: CaptureFrameOptions

      Returns Promise<null | Blob>

    captureVideo

    • Capture a video as a stream of image Blobs with the desired width, height and format. The number of frames per second and total frame count are specified as well.

      Parameters

      • options: CaptureVideoOptions

      Returns ReadableStream<null | Blob>

    clearAnnotations

    clearTileCache

    • Clear the current cache of tiles. The intended use case here is if a network issue caused a necessary tile to not load. This should only be used when necessary, as any previously downloaded tiles will need to be re-fetched.

      Returns void

    createTableLayer

    deleteLayer

    • Delete the specified layer from the layer manager.

      A layer may be identified by either its name or its id.

      Parameters

      • id: string | Guid

      Returns void

    getCatalogHipsDataInView

    • Request an export of the catalog HiPS data within the current viewport.

      Parameters

      • options: GetCatalogHipsDataInViewOptions

      Returns Promise<InViewReturnMessage>

    gotoRADecZoom

    • Command the view to steer to a specific configuration.

      The async action completes when the view arrives, or when a subsequent view command overrides this one.

      TODO: document semantics when not in 2D sky mode!

      Parameters

      Returns Promise<void>

    gotoTarget

    • Command the view to steer as specified in the options.

      The async action completes when the view arrives, or when a subsequent view command overrides this one.

      Parameters

      • options: GotoTargetOptions

      Returns Promise<void>

    loadFitsLayer

    • Deprecated. Use addImageSetLayer instead. Request the creation of a FITS image layer.

      The action resolves to a new ImageSetLayer instance. It’s asynchronous because the requested FITS file has to be downloaded.

      Parameters

      • options: LoadFitsLayerOptions

      Returns Promise<ImageSetLayer>

    loadImageCollection

    • Request the engine to load the specified image collection.

      The image collection is a WTML file Images in collections loaded this way become usable for name-based lookup by interfaces such as setForegroundImageByName.

      The action resolves to a Folder instance. It’s asynchronous because the specified WTML file has to be downloaded.

      Parameters

      Returns Promise<Folder>

    loadTour

    • Request the engine to load a tour file.

      The action resolves when the load is complete. It’s asynchronous because the full WTT tour file has to be downloaded.

      Parameters

      Returns Promise<void>

    move

    • Moves the position of the view

      Parameters

      • args: {
            x: number;
            y: number;
        }
        • x: number
        • y: number

      Returns void

    removeAnnotation

    removeCatalogHipsByName

    • Remove a "catalog HiPS" dataset to the current view, by name.

      Parameters

      • name: string

      Returns void

    seekToTourTimecode

    • Seek tour playback to the specified timecode.

      See tourTimecode for a definition of the tour timecode.

      An important limitation is that the engine can only seek to the very beginning of a tour stop. If you request a timecode in the middle of a slide, the seek will actually occur to the start time of that slide.

      Parameters

      • value: number

      Returns void

    setBackgroundImageByName

    • Set the current background Imageset based on its name.

      The name lookup here is effectively done using lookupImageset. If the name is not found, the current background imageset remains unchanged.

      Changing the background imageset may change the value of renderType, and the overall "mode" of the WWT renderer.

      Parameters

      • imagesetName: string

      Returns void

    setClockRate

    • Set the rate at which the WWT clock progresses compared to wall-clock time.

      A value of 10 means that the WWT clock progresses ten times faster than real time. A value of -0.1 means that the WWT clock moves backwards, ten times slower than real time.

      Altering this causes an increment in clockDiscontinuities.

      Parameters

      • rate: number

      Returns void

    setClockSync

    • Set whether the WWT clock should progress with real time.

      See SpaceTimeController.set_syncToClock(). This interface effectively allows you to pause the WWT clock.

      Altering this causes an increment in clockDiscontinuities.

      Parameters

      • isSynced: boolean

      Returns void

    setFitsLayerColormap

    • Set the colormap used for a FITS image layer according to the options.

      Parameters

      • options: SetFitsLayerColormapOptions

      Returns void

    setForegroundImageByName

    • Set the current foreground Imageset based on its name.

      The name lookup here is effectively done using lookupImageset. If the name is not found, the current foreground imageset remains unchanged.

      Parameters

      • imagesetName: string

      Returns void

    setForegroundOpacity

    • Set the opacity of the foreground imageset.

      Valid values are between 0 (invisible) and 100 (fully opaque).

      Parameters

      • opacity: number

      Returns void

    setImageSetLayerOrder

    setTime

    • Set the current time of WWT's internal clock.

      Altering this causes an increment in clockDiscontinuities.

      Parameters

      • time: Date

      Returns void

    setTourPlayerLeaveSettingsWhenStopped

    • Set whether the renderer settings of tours should remain applied after those tours finish playing back.

      This specialized option helps avoid jarring visual effects when tours finish playing. If a tour activates a renderer option like "local horizon mode", by default that option will turn off when the tour finishes, causing the view to suddenly change. If this option is set to True, that setting will remain active, preventing the sudden change.

      Parameters

      • value: boolean

      Returns void

    setTrackedObject

    setupForImageset

    • Set up the background and foreground imagesets according to the options

      The main use of this interface is that it provides a mechanism to guess the appropriate background imageset given a foreground imageset that you want to show.

      Parameters

      Returns void

    startTour

    • Start playback of the currently loaded tour.

      Nothing happens if no tour is loaded.

      Returns void

    stretchFitsLayer

    tilt

    • Tilts the position of the view

      Parameters

      • args: {
            x: number;
            y: number;
        }
        • x: number
        • y: number

      Returns void

    timeToRADecZoom

    toggleTourPlayPauseState

    • Toggle the play/pause state of the current tour.

      Nothing happens if no tour is loaded.

      Returns void

    updateTableLayer

    viewAsTourXml

    • Get the current view as a one-slide tour, serialized to XML

      Parameters

      • name: string

      Returns Promise<null | string>

    waitForReady

    • Wait for the WWT engine to become ready for usage.

      You should invoke this action and wait for is completion before trying to do anything else with a WWT-aware component. The action resolves when the WWT engine has completed its initialization, which involes the download of some supporting data files.

      Returns Promise<void>

    zoom

    • Set the zoom level of the view.

      This action may result in an action that takes a perceptible amount of time to resolve, if the "smooth pan" renderer option is enabled. To have proper asynchronous feedback about when the zoom operation completes, use gotoRADecZoom.

      Parameters

      • factor: number

      Returns void
