C Specification

The XrSpaceVelocity structure is defined as:

// Provided by XR_VERSION_1_0
typedef struct XrSpaceVelocity {
    XrStructureType         type;
    void*                   next;
    XrSpaceVelocityFlags    velocityFlags;
    XrVector3f              linearVelocity;
    XrVector3f              angularVelocity;
} XrSpaceVelocity;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR.

  • velocityFlags is a bitfield, with bit masks defined in XrSpaceVelocityFlagBits, to indicate which members contain valid data. If none of the bits are set, no other fields in this structure should be considered to be valid or meaningful.

  • linearVelocity is the relative linear velocity of the origin of xrLocateSpace::space with respect to and expressed in the reference frame of xrLocateSpace::baseSpace, in units of meters per second.

  • angularVelocity is the relative angular velocity of xrLocateSpace::space with respect to xrLocateSpace::baseSpace. The vector’s direction is expressed in the reference frame of xrLocateSpace::baseSpace and is parallel to the rotational axis of xrLocateSpace::space. The vector’s magnitude is the relative angular speed of xrLocateSpace::space in radians per second. The vector follows the right-hand rule for torque/rotation.
