Detailed Description

Pose representation derived from the Rotation class

The rotation part of the transformation is handled by Rotation . The translation part is stored internally using homogeneous 4-vector.

Internally in ALVAR we assume coordinate system where 'x' is right, 'y' is down, and 'z' is forward. However the SetMatrixGL and GetMatrixGL change the pose to support coordinates commonly used in OpenGL: 'x' is right, 'y' is up, and 'z' is backward.

Examples:

SampleCamCalib.cpp, SampleMarkerCreator.cpp, SampleMarkerDetector.cpp, SampleMarkerHide.cpp, SampleMarkerlessDetector.cpp, SampleMultiMarker.cpp, SampleMultiMarkerBundle.cpp, and SamplePointcloud.cpp.
