# Module ltp

Local Tangent Plane (LTP) and local cartesian coordinates.

Local cartesian and local tangent plane classes LocalCartesian and Ltp, LocalError and Attitude and Frustum.

See Also: Local tangent plane coordinates and class LocalCartesian, transcoded from Charles Karney's C++ classLocalCartesian.

Version: 21.11.28

Classes
| Attitude The orientation of a plane or camera in space.
| AttitudeError An Attitude or Attitude4Tuple issue.
| Frustum A rectangular pyramid, typically representing a camera's field-of-view (fov) and the intersection with (or projection to) a local tangent plane.
| LocalError A LocalCartesian or Ltp related issue.
| LocalCartesian Conversion between geodetic `(lat, lon, height)` and local cartesian `(x, y, z)` coordinates with geodetic origin `(lat0, lon0, height0)`, transcoded from Karney's C++ class LocalCartesian.
| Ltp A local tangent plan LTP, a sub-class of `LocalCartesian` with configurable ECEF converter and without optional rotation matrix.

Function Details

### tyr3d (tilt=0, yaw=0, roll=0, Vector=<class 'pygeodesy.vector3d.Vector3d'>, **Vector_kwds) |
Convert an attitude oriention into a (3-D) direction vector. Arguments: `tilt` - Pitch, elevation from horizontal (`degrees`), negative down (clockwise rotation along and around the x-axis). `yaw` - Bearing, heading (compass `degrees360`), clockwise from North (counter-clockwise rotation along and around the z-axis). `roll` - Roll, bank (`degrees`), positive to the right and down (clockwise rotation along and around the y-axis). Returns: A named `Vector` instance or if `Vector` is `None`, a named Vector3Tuple`(x, y, z)`. See Also: Yaw, pitch, and roll rotations and function pygeodesy.hartzell argument `los`.
