Member Function Documentation

void TrackerData::clear ( ) [inline]

Removes all data from the structure.

Definition at line 42 of file trackerData.I.

double TrackerData::get_dt ( ) const [inline]

Returns the amount of elapsed time over which the information (pos and orient) were computed.

It is an error to call this if has_dt() does not return true. See set_dt().

Definition at line 206 of file trackerData.I.

References has_dt().

const LOrientation & TrackerData::get_orient ( ) const [inline]

Returns the current orientation of the tracker.

It is legal to call this if has_orient() returns false; in this case, the result is always the identity orientation.

Definition at line 162 of file trackerData.I.

References has_orient(), and LQuaternionf::ident_quat().

Referenced by TrackerNode::do_transmit_data(), and TrackerNode::get_orient().

const LPoint3 & TrackerData::get_pos ( ) const [inline]

Returns the current position of the tracker.

It is legal to call this if has_pos() returns false; in this case, the position will always be (0, 0, 0).

Definition at line 118 of file trackerData.I.

References has_pos().

double TrackerData::get_time ( ) const [inline]

Returns the time at which the position information (pos and orient) are effective.

It is an error to call this if has_time() does not return true. See set_time().

Definition at line 81 of file trackerData.I.

bool TrackerData::has_dt ( ) const [inline]

Returns true if the computed elapsed time is available.

See set_dt().

bool TrackerData::has_orient ( ) const [inline]

Returns true if the current orientation is available.

See set_orient().

Definition at line 149 of file trackerData.I.

bool TrackerData::has_pos ( ) const [inline]

Returns true if the current position is available.

See set_pos().

Definition at line 106 of file trackerData.I.

Referenced by get_pos().

bool TrackerData::has_time ( ) const [inline]

Returns true if the position information time is available.

See set_time().

Referenced by get_time(), and TrackerNode::has_time().

void TrackerData::set_dt ( double  dt) [inline]

Indicates the amount of elapsed time over which which the information (pos and orient) were computed.

This only makes sense if the information represents velocity or acceleration, rather than position. This is an elapsed time in seconds.

Definition at line 181 of file trackerData.I.

void TrackerData::set_orient ( const LOrientation &  orient) [inline]

Indicates the current orientation of the tracker sensor in space.

The coordinate system of this orientation is defined by the tracker, but should be the same coordinate system as that reflected by set_pos().

Definition at line 137 of file trackerData.I.

void TrackerData::set_pos ( const LPoint3 &  pos) [inline]

Indicates the current position of the tracker sensor in space.

The coordinate system of this position is defined by the tracker.

Definition at line 94 of file trackerData.I.

void TrackerData::set_time ( double  time) [inline]

Indicates the time at which the position information (pos and orient) are effective.

This is a time elapsed in seconds since some undefined epoch; it may or may not correspond to the clock time indicated in the global ClockObject.
