Description

pose_composepose_composePoseComposePoseComposepose_compose combines the poses in the tuples, PoseLeftPoseLeftPoseLeftposeLeftpose_left and PoseRightPoseRightPoseRightposeRightpose_right. If both tuples contain the same number of poses, the corresponding elements of both tuples are composed. Otherwise, either tuple PoseLeftPoseLeftPoseLeftposeLeftpose_left or PoseRightPoseRightPoseRightposeRightpose_right must contain only one pose. In this case, the composition is performed for each pose of the longer tuple with the single pose of the other tuple. For each composition, the poses are interpreted as transformations of coordinate systems. The poses in tuple PoseComposePoseComposePoseComposeposeComposepose_compose are therefore the result of applying the corresponding poses in PoseLeftPoseLeftPoseLeftposeLeftpose_left and PoseRightPoseRightPoseRightposeRightpose_right in sequence.

First, the respective poses in PoseLeftPoseLeftPoseLeftposeLeftpose_left and PoseRightPoseRightPoseRightposeRightpose_right are transformed into the corresponding homogeneous transformation matrices and . is then multiplied with . The resulting matrix is converted into a pose and returned at the corresponding index in tuple PoseComposePoseComposePoseComposeposeComposepose_compose.

If the respective poses in PoseLeftPoseLeftPoseLeftposeLeftpose_left and PoseRightPoseRightPoseRightposeRightpose_right have different types, the default pose type 0 ('Rp+T', 'gba', 'point') is returned. Otherwise, the returned poses have the same types as the poses used for their composition.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
