SceneViewGetAllHitObjects(Ray, HitTestOptions) Method

public List<RayHitTestResult> GetAllHitObjects(
	Ray ray,
	HitTestOptions? customHitTestOptions = null
)

Parameters

ray  Ray

Ray object that defines the ray that is used for hit testing

customHitTestOptions  HitTestOptions  (Optional)

Optional HitTestOptions that will be used for this hit test. When null (by default), then DefaultHitTestOptions from Scene will be used.

Return Value

GetAllHitObjects method executes a hit testing on the SceneNodes that are shown by this SceneView and returns a list of RayHitTestResult objects sorted from the closest to the farthest object. When no object is hit, an empty list is returned.

This method takes a Ray as a parameter. The ray can be created by the GetRayFromCamera(Single, Single, Boolean) or GetRayFromNearPlane(Single, Single, Boolean) methods. You can also use the GetAllHitObjects(Single, Single, Boolean, HitTestOptions) method that takes mouse coordinates instead of a Ray.

To control advanced hit-testing options set the customHitTestOptions parameter (HitTestOptions) or change the Scene.DefaultHitTestOptions that is used when customHitTestOptions parameter is not set (null by default).

To get only the closest hit result, use the GetClosestHitObject(Single, Single, Boolean, HitTestOptions) or GetClosestHitObject(Ray, HitTestOptions) methods.
