MapView.intersectMapObjects() method

Do a raycast on all objects in the scene. Useful for picking.

Signature:

intersectMapObjects(x: number, y: number, parameters?: IntersectParams): PickResult[];

Parameters

Parameter	Type	Description
x	number	The X position in css/client coordinates (without applied display ratio).
y	number	The Y position in css/client coordinates (without applied display ratio).
parameters	IntersectParams	(Optional) The intersection test behaviour may be adjusted by providing an instance of .

Returns:

[PickResult](./flywave-mapview.pickresult.md)<!-- -->\[\]

The list of intersection results.

## Remarks

Limited to objects that THREE.js can raycast, the solid lines that get their geometry in the shader cannot be tested for intersection.

Note, if a [DataSource](./flywave-mapview.datasource.md) adds an \[\[Object3D\]\] to a [Tile](./flywave-mapview.tile.md)<!-- -->, it will be only pickable once  has been called, this is because  method creates the internal three.js root \[\[Object3D\]\] which is used in the \[\[PickHandler\]\] internally. This method will not test for intersection custom objects added to the scene by for example calling directly the \[\[scene.add\]\] method from THREE.
