VertexPicker

A class that provides functionality for picking vertices in a 3D scene.

Extends​

Implements​

Properties​

components​

components: Components

A reference to the Components instance associated with this VertexPicker.

Overrides​

Component.components


onDisposed​

readonly onDisposed: Event<unknown>

Disposable.onDisposed

Implementation of​

Disposable . onDisposed


onEnabled​

readonly onEnabled: Event<boolean>

An event that is triggered when the picker is enabled or disabled


onVertexFound​

readonly onVertexFound: Event<Vector3>

An event that is triggered when a vertex is found. The event passes a THREE.Vector3 representing the position of the found vertex.


onVertexLost​

readonly onVertexLost: Event<Vector3>

An event that is triggered when a vertex is lost. The event passes a THREE.Vector3 representing the position of the lost vertex.


workingPlane​

workingPlane: null | Plane = null

A reference to the working plane used for vertex picking. This plane is used to determine which vertices are considered valid for picking. If this value is null, all vertices are considered valid.

Accessors​

config​

get config(): Partial <VertexPickerConfig>

Gets the current configuration for the VertexPicker component.

Example​

const currentConfig = vertexPicker.config;
console.log(currentConfig.snapDistance); // Output: 0.25

set config(value): void

Sets the configuration for the VertexPicker component.

Example​

vertexPicker.config = {
snapDistance: 0.5,
showOnlyVertex: true,
};

Parameters​

ParameterTypeDescription
valuePartial <VertexPickerConfig>A Partial object containing the configuration properties to update.
The properties not provided in the value object will retain their current values.

Returns​

Partial <VertexPickerConfig>

A copy of the current VertexPickerConfig object.


enabled​

get enabled(): boolean

Gets the current enabled state of the VertexPicker.

set enabled(value): void

Sets the enabled state of the VertexPicker. When enabled, the VertexPicker will actively search for vertices in the 3D scene. When disabled, the VertexPicker will stop searching for vertices and reset the picked point.

Parameters​

ParameterTypeDescription
valuebooleanThe new enabled state.

Returns​

boolean

The current enabled state.

Methods​

dispose()​

dispose(): void

Disposable.dispose

Returns​

void

Implementation of​

Disposable . dispose


get()​

get(world): Promise<null | Vector3>

Performs the vertex picking operation based on the current state of the VertexPicker.

Parameters​

ParameterTypeDescription
worldWorldThe World instance to use for raycasting.

Returns​

Promise<null | Vector3>

The current picked point, or null if no point is picked.

Remarks​

This method checks if the VertexPicker is enabled. If not, it returns the current picked point. If enabled, it performs raycasting to find the closest intersecting object. It then determines the closest vertex or point on the face, based on the configuration settings. If the picked point is on the working plane (if defined), it triggers the onVertexFound event and updates the pickedPoint. If the picked point is not on the working plane, it resets the pickedPoint. If no intersecting object is found, it triggers the onVertexLost event and resets the pickedPoint.
