Enumerations

ArPointOrientationMode

ArPointOrientationMode

Indicates the orientation mode of the ArPoint .

Properties

 AR_POINT_ORIENTATION_ESTIMATED_SURFACE_NORMAL

The orientation of the ArPoint will follow the behavior described in ArHitResult_getHitPose .

 AR_POINT_ORIENTATION_INITIALIZED_TO_IDENTITY

The orientation of the ArPoint is initialized to identity but may adjust slightly over time.

Typedefs

ArPoint

struct ArPoint_ ArPoint

An arbitrary point in space ( reference type, long-lived ).

Trackable type: AR_TRACKABLE_POINT
Release with: ArTrackable_release

Functions

ArPoint_getOrientationMode

 void 
  
 ArPoint_getOrientationMode 
 ( 
  
 const 
  
  ArSession 
 
  
 * 
 session 
 , 
  
 const 
  
  ArPoint 
 
  
 * 
 point 
 , 
  
  ArPointOrientationMode 
 
  
 * 
 out_orientation_mode 
 )

Returns the ArPointOrientationMode of the point.

For ArPoint objects created by ArFrame_hitTest . If ArPointOrientationMode is AR_POINT_ORIENTATION_ESTIMATED_SURFACE_NORMAL , then normal of the surface centered around the ArPoint was estimated successfully.

Details

Parameters

`session`	The ARCore session.
`point`	The point to retrieve the pose of.
`out_orientation_mode`	OrientationMode output result for the point.

ArPoint_getPose

 void 
  
 ArPoint_getPose 
 ( 
  
 const 
  
  ArSession 
 
  
 * 
 session 
 , 
  
 const 
  
  ArPoint 
 
  
 * 
 point 
 , 
  
  ArPose 
 
  
 * 
 out_pose 
 )

Returns the pose of the point.

If ArPoint_getOrientationMode returns AR_POINT_ORIENTATION_ESTIMATED_SURFACE_NORMAL , the orientation will follow the behavior described in ArHitResult_getHitPose . If ArPoint_getOrientationMode returns AR_POINT_ORIENTATION_INITIALIZED_TO_IDENTITY , then returns an orientation that is identity or close to identity.

Details

Parameters

`session`	The ARCore session.
`point`	The point to retrieve the pose of.
`out_pose`	An already-allocated `ArPose` object into which the pose will be stored.
