Syntax

public class DXRayHitTestResult : DXHitTestResult

The DXRayHitTestResult type exposes the following members.

Constructors

	Name	Description
	DXRayHitTestResult(Vector3, Single)	Constructor
	DXRayHitTestResult(Vector3, SceneNode, Single)	Constructor

Fields

	Name	Description
	DistanceToRayOrigin	Distance to the ray's origin.
	HitPosition	Vector3 that specifies hit position.
	IsBackFacing	When false, then the ray hit the front facing triangle (triangle's normal is facing in the opposite direction as the ray). When true, then back facing triangle was hit. The triangle's normal is calculated as normal = Vector3.Cross(p1 - p2, p1 - p3) where p1, p2 and p3 are triangle positions based on the triangle indices.
	TriangleIndex	Index of the hit triangle. TriangleIndex can be converted into an index in the TriangleIndices collection or in indexBuffer with multiplying the TriangleIndex by 3.
