quat_composeT_quat_composeQuatComposeQuatComposequat_compose (Operator)
Name
quat_composeT_quat_composeQuatComposeQuatComposequat_compose — Multiply two quaternions.
Signature
Description
The operator quat_composequat_composeQuatComposeQuatComposequat_compose multiplies the two quaternions
QuaternionLeftQuaternionLeftQuaternionLeftquaternionLeftquaternion_left and QuaternionRightQuaternionRightQuaternionRightquaternionRightquaternion_right and returns the
result in QuaternionComposedQuaternionComposedQuaternionComposedquaternionComposedquaternion_composed.
A quaternion is given by
.
In HALCON, a quaternion is represented by a four value tuple:
.
The product of two quaternions and is defined as:
As a consequence, the multiplication of two quaternions is not
commutative, i.e. .
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
