API Reference › core-frontend› Views › OffScreenViewport

OffScreenViewport Class

A viewport that draws to an offscreen buffer instead of to the screen. An offscreen viewport is never added to the ViewManager, therefore does not participate in the render loop. Its dimensions are specified directly instead of being derived from an HTMLCanvasElement, and its renderFrame function must be manually invoked. Offscreen viewports can be useful for, e.g., producing an image from the contents of a view (see readImageBuffer and readImageToCanvas) without drawing to the screen.

@see OffScreenViewport.create to create an off-screen viewport.

Properties

Name Type Description
_isAspectRatioLocked Protected boolean    
viewRect Accessor ReadOnly ViewRect Get the rectangle of this Viewport in CoordSystem.View coordinates.  

Inherited properties

Name Type Inherited from Description
_decorationsValid Protected Inherited boolean Viewport If false, indicates that Decorations should be recreated when rendering the next frame.
alwaysDrawn Accessor Inherited ReadOnly undefined | Id64Set Viewport Ids of a set of elements which should always be rendered within this view, regardless of category and subcategory visibility.
If the isAlwaysDrawnExclusive flag is also set, only those elements in this set will be drawn.
analysisFraction Accessor Inherited number Viewport See DisplayStyleSettings.analysisFraction.
antialiasSamples Accessor Inherited number Viewport Sets the number of MSAA samples for this viewport.
The number of samples is a power of two. Values of 1 or less indicates anti-aliasing should be disabled. Non-power-of-two values are rounded
down to the nearest power of two. The maximum number of samples supported depends upon the client's graphics hardware capabilities. Higher values produce
a higher-quality image but also may also reduce framerate.
areAllTileTreesLoaded Accessor Inherited ReadOnly boolean Viewport Returns true if all TileTrees required by this viewport have been loaded.
auxCoordSystem Accessor Inherited ReadOnly AuxCoordSystemState Viewport  
backgroundMapSettings Accessor Inherited BackgroundMapSettings Viewport The settings controlling how a background map is displayed within a view.
clipStyle Accessor Inherited ClipStyle Viewport See DisplayStyleSettings.clipStyle
continuousRendering Accessor Inherited boolean Viewport Enables or disables continuous rendering. Ideally, during each render frame a Viewport will do as little work as possible.
To make that possible, the viewport keeps track of what has changed about its internal state from one frame to the next.
For example, if the view frustum has not changed since the previous frame, it is likely that the viewport does not need to be
re-rendered at all.

In some circumstances, it is desirable to bypass the logic that limits the amount of work performed each frame. A primary example
is a viewport that has some animations applied to it, or when diagnostic information like frames-per-second is being monitored.
debugBoundingBoxes Accessor Inherited TileBoundingBoxes Viewport Determines what type (if any) of debug graphics will be displayed to visualize Tile volumes. Chiefly for debugging.
devicePixelRatio Accessor Inherited ReadOnly number Viewport The device pixel ratio used by this Viewport. This value is not necessarily equal to window.devicePixelRatio.
See: https://developer.mozilla.org/en-US/docs/Web/API/Window/devicePixelRatio
displayStyle Accessor Inherited DisplayStyleState Viewport See displayStyle
emphasisSettings Accessor Inherited Hilite.Settings Viewport The settings that control how emphasized elements are displayed in this Viewport. The default settings apply a thick black silhouette to the emphasized elements.
featureOverrideProviders Accessor Inherited ReadOnly Iterable<FeatureOverrideProvider, any, any> Viewport The list of FeatureOverrideProviders registered with this viewport.
flashedId Accessor Inherited undefined | string Viewport The Id of the currently-flashed object.
The "flashed" visual effect is typically applied to the object in the viewport currently under the mouse cursor, to indicate
it is ready to be interacted with by a tool. ToolAdmin is responsible for updating it when the mouse cursor moves.
The object is usually an Element but could also be a Model or pickable decoration produced by a Decorator.
The setter ignores any string that is not a well-formed Id64String. Passing Id64.invalid to the
setter is equivalent to passing undefined - both mean "nothing is flashed".
flashSettings Accessor Inherited FlashSettings Viewport The settings that control how elements are flashed in this viewport.
hilite Accessor Inherited Hilite.Settings Viewport The settings that control how elements are hilited in this Viewport.
iModel Accessor Inherited ReadOnly IModelConnection Viewport The iModel of this Viewport
isAlwaysDrawnExclusive Accessor Inherited ReadOnly boolean Viewport Returns true if the set of elements in the alwaysDrawn set are the only elements rendered within this view.
isCameraOn Accessor Inherited ReadOnly boolean Viewport True if this is a 3d view with the camera turned on.
isDisposed Accessor Inherited ReadOnly boolean Viewport Returns true if this Viewport's dispose method has been invoked. It is an error to attempt to interact with a disposed Viewport.
Typically a ScreenViewport becomes disposed as a result of a call to dropViewport, often indirectly through the unmounting of a nine-zone UI's ViewportComponent when, e.g., switching front-stages.
isFadeOutActive Accessor Inherited boolean Viewport Enables or disables "fade-out" mode. When this mode is enabled, transparent graphics are rendered with a flat alpha weight,
causing them to appear de-emphasized. This is typically used in contexts in which a handful of elements are to be emphasized in the view,
while the rest of the graphics are drawn transparently.
isGridOn Accessor Inherited ReadOnly boolean Viewport Determine whether the Grid display is currently enabled in this Viewport.
lastFlashedElementId Accessor Inherited ReadOnly undefined | string Viewport The Id of the most recently flashed element, if any.
lightSettings Accessor Inherited ReadOnly undefined | LightSettings Viewport See DisplayStyle3dSettings.lights
neverDrawn Accessor Inherited ReadOnly undefined | Id64Set Viewport Ids of a set of elements which should not be rendered within this view.
numReadyTiles Accessor Inherited ReadOnly number Viewport The number of tiles which were ready and met the desired level-of-detail for display in the view as of the most recently-drawn frame.
These tiles may not have been selected because some other (probably sibling) tiles were not ready for display.
This is a useful metric for determining how "complete" the view is - e.g., one indicator of progress toward view completion can be expressed as:
(numReadyTiles) / (numReadyTiles + numRequestedTiles)
numRequestedTiles Accessor Inherited ReadOnly number Viewport The number of outstanding requests for tiles to be displayed in this viewport.
numSelectedTiles Accessor Inherited ReadOnly number Viewport The number of tiles selected for display in the view as of the most recently-drawn frame.
The tiles selected may not meet the desired level-of-detail for the view, instead being temporarily drawn while
tiles of more appropriate level-of-detail are loaded asynchronously.

onFlashedIdChanged Readonly Inherited BeEvent<(vp: Viewport, args: OnFlashedIdChangedEventArgs) => void> Viewport Event dispatched immediately after flashedId changes, supplying the Ids of the previously and/or currently-flashed objects.
onMapLayerScaleRangeVisibilityChanged Readonly Inherited BeEvent<(layerIndexes: MapLayerScaleRangeVisibility[]) => void> Viewport Event indicating when a map-layer scale range visibility change for the current viewport scale.
onNeverDrawnChanged Readonly Inherited BeEvent<(vp: Viewport) => void> Viewport Event called on the next frame after this viewport's set of never-drawn elements changes.
onRender Readonly Inherited BeEvent<(vp: Viewport) => void> Viewport Called when the visible contents of the viewport are redrawn.
onResized Readonly Inherited BeEvent<(vp: Viewport) => void> Viewport Event invoked after renderFrame detects that the dimensions of the viewport's ViewRect have changed.
onSceneInvalidated Readonly Inherited BeEvent<(vp: Viewport) => void> Viewport Event invoked every time invalidateScene is called.
onViewChanged Readonly Inherited BeEvent<(vp: Viewport) => void> Viewport Event called whenever this viewport is synchronized with its ViewState.

rotation Accessor Inherited ReadOnly Matrix3d Viewport This viewport's rotation matrix.
screenSpaceEffects Accessor Inherited Iterable<string, any, any> Viewport An ordered list of names of screen-space post-processing effects to be applied to the image rendered by the Viewport.
The effects are applied to the image in the order in which they appear in the list. Any names not corresponding to a registered effect are ignored.
This may have no effect if the Viewport's RenderTarget does not support screen-space effects.
