Typedef Documentation

◆ ArPose

typedef struct ArPose_ ArPose

A structured rigid transformation (value type).

Allocate with ArPose_create()
Release with ArPose_destroy()

Definition at line 175 of file arcore_c_api.h.

Function Documentation

◆ ArPose_create()

void ArPose_create ( const ArSession session,
const float *  pose_raw,
ArPose **  out_pose 
)

Allocates and initializes a new pose object. pose_raw points to an array of 7 floats, describing the rotation (quaternion) and translation of the pose in the same order as the first 7 elements of the Android Sensor.TYPE_POSE_6DOF values documented on SensorEvent.values()

The order of the values is: qx, qy, qz, qw, tx, ty, tz.

If pose_raw is null, initializes with the identity pose.

◆ ArPose_destroy()

void ArPose_destroy ( ArPose pose)

Releases memory used by a pose object.

◆ ArPose_getMatrix()

void ArPose_getMatrix ( const ArSession session,
const ArPose pose,
float *  out_matrix_col_major_4x4 
)

Converts a pose into a 4x4 transformation matrix.

Parameters
[in]sessionThe ARCore session
[in]poseThe pose to convert
[out]out_matrix_col_major_4x4Pointer to an array of 16 floats, to be filled with a column-major homogenous transformation matrix, as used by OpenGL.

◆ ArPose_getPoseRaw()

void ArPose_getPoseRaw ( const ArSession session,
const ArPose pose,
float *  out_pose_raw 
)

Extracts the quaternion rotation and translation from a pose object.

Parameters
[in]sessionThe ARCore session
[in]poseThe pose to extract
[out]out_pose_rawPointer to an array of 7 floats, to be filled with the quaternion rotation and translation as described in ArPose_create().
