hom_mat3d_to_pose — Convert a homogeneous transformation matrix into a 3D pose.
hom_mat3d_to_pose converts a homogeneous transformation matrix into the corresponding 3D pose with type code 0. For details about 3D poses and the corresponding transformation matrices please refer to create_pose.
A typical application of hom_mat3d_to_pose is that a 3D pose was converted into a homogeneous transformation matrix to further transform it, e.g., with hom_mat3d_rotate or hom_mat3d_translate, and now must be converted back into a pose to use it as input for operators like image_points_to_world_plane.
hom_mat3d_to_pose only supports rigid transformations in HomMat3D.
