Draws a crosshair from the location to the walls of the bounding box (defined by worldDimensions). Properties stroke, strokeThickness and antiAliased can be used to customize the appearance of the line. The CrosshairLinesSceneEntity inherits BaseSceneEntity3D and can be added to the SciChart3DSurface via the SciChart3DSurface.rootEntity property.

Properties

antiAliased

antiAliased: boolean = true

Whether crosshair lines are antialiased or not

cameraPosition

cameraPosition: Vector3

The camera position in 3D space, which is used to compute vectors

Readonly children

summary

Gets the collection of IBaseSceneEntity - child entities or 3D Objects which belong to this entity.

description

A SciChart3DSurface has a SciChart3DSurface.rootEntity property. You can add BaseSceneEntity3D to this property, and each entity can have a collection of child entities.

Use grouping to control visibility of many entities at once, or to create more complex scenes.

remarks

Adding a BaseSceneEntity3D to the children collection will cause the 3D Scene to be redrawn.

Protected currentRenderPassData

currentRenderPassData: RenderPassInfo3D

The RenderPassInfo3D containing data about the current rendering pass

Readonly id

id: string = generateGuid()

A unique Id for the IBaseSceneEntity

isVisible

isVisible: boolean = true

When true, the entity and all its children are visible

location

location: Vector3

The location of the crosshair in 3D space

parent

Gets the parent Entity

Readonly rootSceneEntity

rootSceneEntity: RootSceneEntity
inheritdoc

stroke

stroke: string = "#FF6600"

The stroke of crosshair lines

strokeThickness

strokeThickness: number = 2

The strokethickness of crosshair lines

Readonly type

type: Custom = ESceneEntityType.Custom

Gets the type of Scene Entity. See ESceneEntityType for a list of values

Protected webAssemblyContext

webAssemblyContext: TSciChart3D

The SciChart 3D WebAssembly Context containing native methods and access to our WebGL2 Engine and WebAssembly numerical methods

worldDimensions

worldDimensions: Vector3

The world dimensions of the bounding box, which should match SciChart3DSurface.worldDimensions

Accessors

entityId

  • get entityId(): number
  • set entityId(value: number): void
  • Gets or sets a unique Id for the IBaseSceneEntity. The SciChart3D engine requires Ids fit into UInt32 (4 billion)

    inheritdoc

    Returns number

  • Gets or sets a unique Id for the IBaseSceneEntity. The SciChart3D engine requires Ids fit into UInt32 (4 billion)

    inheritdoc

    Parameters

    • value: number

    Returns void

entityIdProvider

nativeEntity

  • get nativeEntity(): SCRTSceneEntity
  • Gets the native SCRTSceneEntity - a WebAssembly 3D Scene Entity type which is passed to our WebGL WebAssembly 3D Engine

    inheritdoc

    Returns SCRTSceneEntity

Protected world

  • get world(): SCRTSceneWorld
  • Called internally - gets the world entity

    Returns SCRTSceneWorld

Methods

Render

  • Render(): void
  • inheritdoc

    Returns void

Update

  • Update(deltaTime: number): void
  • Update method called from WebAssembly engine. Use this to update meshes, properties, geometry before draw. When overriding, you must call super.Update() for the object to draw in the scene

    Parameters

    • deltaTime: number

    Returns void

Protected attachChild

  • Called internally - Attach a child to the current entity

    Parameters

    Returns void

delete

  • delete(): void
  • Deletes native (WebAssembly) memory used by this type, after which it cannot be used.

    remarks

    Call .delete() before finishing with the object to ensure that WebAssmembly memory leaks do not occur.

    All elements within SciChart's High Performance Realtime JavaScript Charts which implement IDeletable must be deleted manually to free native (WebAssembly) memory

    Returns void

Protected detachChild

  • Called internally - detach a child from the current entity

    Parameters

    Returns void

getEntity

getRoot

invalidateScene

  • invalidateScene(): void
  • Call this to inform SciChart that data or properties have changed and the 3D Scene must be redrawn

    Returns void

onAttached

  • onAttached(): void

onDetached

  • onDetached(): void

onDpiChanged

onEngineRestart

  • onEngineRestart(): void

Protected setNativeEntity

  • setNativeEntity(entity: SCRTSceneEntity): void
  • Called internally - sets the native entity

    Parameters

    • entity: SCRTSceneEntity

    Returns void

setRenderPassData

visitEntities
