Methods

Abstract calculate

▸ calculate(): void

Inherited from HintDataProvider.calculate

Defined in src/renderContext/hints/HintDataProvider.ts:15

Trigger recalculation of internally stored values

Returns: void

---

destroy

▸ destroy(): void

Inherited from HintDataProvider.destroy

Defined in src/renderContext/hints/HintDataProvider.ts:20

Called when the hint that uses this provider is destroyed. You want to do cleanup here.

Returns: void

---

getCanvasPoints

▸ getCanvasPoints(): Vector3[]

Defined in src/renderContext/hints/HintPositionProviders/HintPositionProvider.ts:37

Return the edge points of the hint on the screen. Used for filtering hints

Returns: Vector3[]

---

Abstract getPosition

▸ getPosition(): Vector3

Defined in src/renderContext/hints/HintPositionProviders/HintPositionProvider.ts:11

Get internally stored position in canvas space. Will get updated with calculate().

Returns: Vector3

---

Abstract getWorldPosition

▸ getWorldPosition(): Vector3

Defined in src/renderContext/hints/HintPositionProviders/HintPositionProvider.ts:16

Get internally stored position in 3D world space. Will get updated with calculate().

Returns: Vector3

---

Abstract isValid

▸ isValid(): boolean

Inherited from HintDataProvider.isValid

Defined in src/renderContext/hints/HintDataProvider.ts:10

Checks whether this hint is still valid (e.g. edge it annotates still exists)

Returns: boolean

---

setCanvasSizeGetter

▸ setCanvasSizeGetter(getCanvasSize: function): void

Defined in src/renderContext/hints/HintPositionProviders/HintPositionProvider.ts:29

Called by the hint when it's added to the hintManager. The hintManager will provide a function to get the canvas size to the hint, which will foward it to the provider. Override if needed.

Parameters:

▪ getCanvasSize: function

▸ (): IDimensions2

Returns: void

---

setConversionMethod

▸ setConversionMethod(worldToCanvas: function): void

Defined in src/renderContext/hints/HintPositionProviders/HintPositionProvider.ts:22

Called by the hint when it's added to the hintManager. The hintManager will give a worldToCanvas conversion method to the hint, which will forward it to the provider. Override if needed.

Parameters:

▪ worldToCanvas: function

▸ (Vector3: any): Vector3

Parameters:

Name	Type
Vector3	any

Returns: void
