Interface ILineRenderable

Get line points and hit point info for rendering.

Namespace: UnityEngine.XR.Interaction.Toolkit
Syntax
public interface ILineRenderable

Methods

GetLinePoints(ref Vector3[], out Int32)

Gets the polygonal chain represented by a list of endpoints which form line segments to approximate the curve. Positions are in world space coordinates.

Declaration
bool GetLinePoints(ref Vector3[] linePoints, out int numPoints)
Parameters
Type Name Description
Vector3[] linePoints

When this method returns, contains the sample points if successful.
Int32 numPoints

When this method returns, contains the number of sample points if successful.
Returns
Type Description
Boolean

Returns true if the sample points form a valid line, such as by having at least two points. Otherwise, returns false.

TryGetHitInfo(out Vector3, out Vector3, out Int32, out Boolean)

Gets the current ray cast hit information, if a hit occurs. It returns the world position and the normal vector of the hit point, and its position in linePoints.

Declaration
bool TryGetHitInfo(out Vector3 position, out Vector3 normal, out int positionInLine, out bool isValidTarget)
Parameters
Type Name Description
Vector3 position

When this method returns, contains the world position of the ray impact point if a hit occurred.
Vector3 normal

When this method returns, contains the world normal of the surface the ray hit if a hit occurred.
Int32 positionInLine

When this method returns, contains the index of the sample endpoint within the list of points returned by GetLinePoints(ref Vector3[], out Int32) where a hit occurred. Otherwise, a value of 0 if no hit occurred.
Boolean isValidTarget

When this method returns, contains whether both a hit occurred and it is a valid target for interaction.
Returns
Type Description
Boolean

Returns true if a hit occurs, implying the ray cast hit information is valid. Otherwise, returns false.
