# ObjectIntersection Class (CPP)

**Header:** #include <UnigineObjects.h>


This class is used to store the result of the object intersection (coordinates of the intersection point, as well as surface and instance indices).


## ObjectIntersection Class

### Enums

## TYPE

| Name | Description |
|---|---|
| **OBJECT_INTERSECTION** = 0 | [ObjectIntersection](../../../api/library/objects/class.objectintersection_cpp.md) (stores only the point of intersection, surface and triangle indices). |
| **OBJECT_INTERSECTION_NORMAL** = 1 | [ObjectIntersectionNormal](../../../api/library/objects/class.objectintersectionnormal_cpp.md) (stores the point of intersection, surface and triangle indices + normal coordinates at the point of intersection). |
| **OBJECT_INTERSECTION_TEX_COORD** = 2 | [ObjectIntersectionTexCoord](../../../api/library/objects/class.objectintersectiontexcoord_cpp.md) (stores the point of intersection, surface and triangle indices + normal and texture coordinates at the point of intersection). |
| **NUM_OBJECT_INTERSECTIONS** = 3 | Number of object intersection types. |

### Members

## void setInstance ( int instance )

Sets a new number of the intersected instance.
> **Notice:** Intersected instance number can be obtained for the following classes:
> - *[ObjectMeshSkinned](../../../api/library/objects/class.objectmeshskinned_cpp.md)*
> - *[ObjectMeshCluster](../../../api/library/objects/class.objectmeshcluster_cpp.md)*
> - *[ObjectMeshSplineCluster](../../../api/library/objects/class.objectmeshsplinecluster_cpp.md)*

### Arguments

- *int* **instance** - The number of the intersected instance

## int getInstance () const

Returns the current number of the intersected instance.
> **Notice:** Intersected instance number can be obtained for the following classes:
> - *[ObjectMeshSkinned](../../../api/library/objects/class.objectmeshskinned_cpp.md)*
> - *[ObjectMeshCluster](../../../api/library/objects/class.objectmeshcluster_cpp.md)*
> - *[ObjectMeshSplineCluster](../../../api/library/objects/class.objectmeshsplinecluster_cpp.md)*

### Return value

Current number of the intersected instance
## void setIndex ( int index )
