An Atoms operator is an Atoms graph node but with already an out pose port and some function to access the agent what own this node.

The operator in this example add an offset to a joint transformAtomsオペレータは、組み込みのポーズポートと、Ownerエージェントにアクセスするための特定の機能を持つ、特殊なAtomsグラフノードです。この例のオペレータは、ジョイントの変換にオフセットを追加します。
