Configuration options for hit-testing in SCNNode and SCNSceneRenderer
public class SCNHitTestOptions : Foundation.DictionaryContainertype SCNHitTestOptions = class
inherit DictionaryContainer- Inheritance
Remarks
You create an instance of this class to configure how hit-testing should be evaluated by the HitTest methods.
Hit testing uses two 3D vectors in the case of SCNNode and a 2D point in the case of the SCNSceneRenderer.
Constructors
| Name | Description |
|---|---|
| SCNHitTestOptions() |
Creates a new SCNHitTestOptions with default (empty) values. |
| SCNHitTestOptions(NSDictionary) |
Creates a new SCNHitTestOptions from the values that are specified in |
Properties
| Name | Description |
|---|---|
| BackFaceCulling |
Determines whether to ignore polygons that are not facing the camera for hit-testing. |
| BoundingBoxOnly |
Control whether hit-testing uses the node's geometry, or if a bounding-box is used to optmize the hit-testing process speed. |
| Dictionary |
Gets the wrapped NSDictionary. (Inherited from DictionaryContainer) |
| FirstFoundOnly |
Controls whether only the first hit match is returned. Caveat: the first match returned might not be the nearest object. |
| IgnoreChildNodes |
Controls whether hit-testing will consider all nodes of the hierarchy, or only the node specified in the RootNode property. |
| IgnoreHiddenNodes |
Controls whether hit-testing will return hidden nodes or not. |
| IgnoreLightArea | |
| RootNode |
Limits the hit-testing to this node as well as its children (you must also set IgnoreChildNodes). |
| SearchMode | |
| SortResults |
If set, sorts the returned hit-test results from nearest to farthest. |
