C Specification

A pose is defined by the XrPosef structure:

typedef struct XrPosef {
    XrQuaternionf    orientation;
    XrVector3f       position;
} XrPosef;

Members

Member Descriptions

  • orientation is an XrQuaternionf representing the orientation within a space.

  • position is an XrVector3f representing position within a space.

A construct representing a position and orientation within a space, with position expressed in meters, and orientation represented as a unit quaternion. When using XrPosef the rotation described by orientation is always applied before the translation described by position.

Description

A runtime must return XR_ERROR_POSE_INVALID if the orientation norm deviates by more than 1% from unit length.
