Methods
Methods
▸ add(object): CrossHair2DCursor
Adds object as child of this object.
| Name | Type | Description |
|---|---|---|
object | Object3D<Object3DEventMap> | Object3D<Object3DEventMap>[] | object |
this
▸ afterRender(scene, camera, plot, renderer): CrossHair2DCursor
This function is called after rendering and can update this object's content.
It should not trigger any invalidateObject though.
Note that it is not necessary nor recommended to explicitly call afterRender on this object's children as beforeRender will be called on all nodes present in the scene.
This will be executed after the transformations simplification.
See
Plot for more details on the render steps
| Name | Type | Description |
|---|---|---|
scene | Scene | The scene |
camera | Camera | The camera used for this render phase. |
plot | Plot | The 3D plot |
renderer | WebGLRenderer | The renderer |
▸ beforeRender(scene, camera, plot, renderer): CrossHair2DCursor
This function is called prior to rendering and can update this object's content.
It should not trigger any invalidateObject though.
Note that it is not necessary nor recommended to explicitly call beforeRender on this object's children as beforeRender will be called on all nodes present in the scene.
This will be executed after the transformations simplification.

▸ dispose(): void
Dispose object
void
▸ getClassName(): string
string
▸ getOptions(): Required<OptionsBaseOut>
Get options
Required<OptionsBaseOut>
options object
▸ getVisible(): boolean
Get visible
boolean
true, if object is visible
▸ invalidateObject<T>(event?): CrossHair2DCursor
Notifies this object and its parent that this object has been invalidated.
If this object is in a Plot, it will be marked as dirty and will trigger a rendering cycle.
| Name |
|---|
T |
| Name | Type | Description |
|---|---|---|
Optional event | Event<T> | The event to fire |
AbstractCursor.invalidateObject
▸ isDisposed(): boolean
Returns whether this object has been disposed
boolean
▸ isSelectable(): boolean
Return if this object can be picked/selected (see RendererPicking).
boolean
▸ notify(type, source, args?): CrossHair2DCursor
Notify listeners
| Name | Type | Description |
|---|---|---|
type | string | event types |
source | any | of the event |
Optional args | any | arguments of the event |
this
▸ off(type?, callback?): CrossHair2DCursor
Detach listener on event. Calling .off() with no arguments removes all attached listeners. Calling .off(type) with no callback removes all attached listeners for specific type.
| Name | Type | Description |
|---|---|---|
Optional type | string | type of the event |
Optional callback | EventListener | function to be called |
this
▸ off<E>(type, callback): CrossHair2DCursor
| Name | Type |
|---|---|
E | extends string |
| Name | Type |
|---|---|
type | E |
callback | (eventType: E, sender: CrossHair2DCursor, args: EventMap[E]) => void |
▸ on(type, callback, options?): CrossHair2DCursor
Attach listener on event that will be called whenever the specified event is delivered to the target
If the callback function is already in the list of event listeners for this target, the function is not added a second time.
If a particular anonymous function is in the list of event listeners registered for a certain target, and then later in the code, an identical anonymous function is given in an "on" call, the second function will also be added to the list of event listeners for that target.
| Name | Type | Description |
|---|---|---|
type | string | type of event or property |
callback | EventListener | to be called |
Optional options | Options | options of subscription |
this
▸ on<E>(type, callback, options?): CrossHair2DCursor
| Name | Type |
|---|---|
E | extends string |
| Name | Type |
|---|---|
type | E |
callback | (eventType: E, sender: CrossHair2DCursor, args: EventMap[E]) => void |
Optional options | Options |
▸ onStatsUpdated(metrics): CrossHair2DCursor
This function is called when the plot has updated performance metric.
It will be called every set number of frames.
The number of frame is customizable in the plot options advancedrendering.performancemetrics.updateframeperiod and is 100 by default.
| Name | Type | Description |
|---|---|---|
metrics | PerformanceMetrics | The performance metrics. |
▸ Protected onVisibilityChanged(): void
This method is called if visibility is changed. Send event Events.VisibilityChanged
void
AbstractCursor.onVisibilityChanged
▸ remove(object): CrossHair2DCursor
Removes object as child of this object.
| Name | Type | Description |
|---|---|---|
object | Object3D<Object3DEventMap> | Object3D<Object3DEventMap>[] | object |
this
▸ setCursorPosition(position): CrossHair2DCursor
Set the cursor position in world coordinates
| Name | Type | Description |
|---|---|---|
position | Vector3 | The new cursor position |
this
AbstractCursor.setCursorPosition
▸ setOptions(options?): CrossHair2DCursor
Set options, the given json will be merged with the object's state so that only the given options will be changed.
| Name | Type | Description |
|---|---|---|
Optional options | OptionsBase | The options |
this
▸ setPosition(position): CrossHair2DCursor
Set Object's local position.
| Name | Type | Description |
|---|---|---|
position | Object | local position |
Optional position.x | number | |
Optional position.y | number | |
Optional position.z | number |
this
▸ setRotation(x, y, z, order?): CrossHair2DCursor

this
▸ updateObject(scene, camera): CrossHair2DCursor
This function is called prior to rendering and can update this object's content.
It should not trigger any invalidateObject though.
Note that it is not necessary nor recommended to explicitly call updateObject on this object's children as updateObject will be called on all nodes present in the scene.
This will be executed before the transformations simplification.

▸ useOwnHighlight(): boolean
Returns true if this object make its own highlight effect (like geotoolkit3d.scene.reservoir.hexahedral.ReservoirGrid) This is to prevent unnecessary executions of the costly highlight passes.
boolean
AbstractCursor.useOwnHighlight
▸ Static getClassName(): string
string
▸ Static register(): void
Register object for special processing through a callback function
Example
geotoolkit3d.util.ObjectProcessor.getDefaultInstance().registerObject(this.getClassName(), callback);Deprecated
since 5.0, to allow custom object highlighting, please instead make your Object implement the interface geotoolkit3d/scene/ICustomHighlight.
