qc_open_library('quarc_library/Math Operations/Quaternions')Description
The Quaternion to Homogeneous Transformation block converts a unit quaternion to a 4x4 homogeneous transformation.
The block assumes the input is a unit quaternion in order to reduce its computation time, particularly since most of the Quaternion blocks deal with unit quaternions. To normalize a quaternion in order to get a unit quaternion, use the Normalize block, which can normalize vectors or quaternions.
Input Ports
q
The input is the unit quaternion to convert to a homogeneous transformation.
Output Ports
4x4
The output is a 4x4 homogeneous transformation matrix. Multiplying this homogeneous transformation by an augmented vector (i.e. y = R [u 1]') will rotate the vector in the same way as the quaternion when the Quaternion Rotate Vector block is used.
Data Type Support
This block accepts inputs of type double. The block output is
of type double.
Parameters and Dialog Box
The Quaternion to Homogeneous Transformation block has no parameters.
