Mayaviのpipeline
Every visualization created in Mayavi is constructed with a pipeline.ということで、pipelineの構造はこんな感じか？
Engine <- Scenes <- data Sources <- Filter <- Filter <- ... <- Visualization Modules
矢印方向を辿るのがparent attribute、逆方向がchildren attribute。他のattribute、name attributeがあり、nodeの名前が見れる。
Displaying the pipeline view is the easiest way to understand what pipeline was built.ということで、show_pipeline() mlab commandが使える。詳しくはこちら：Assembling pipelines with mlab — mayavi 4.4.4 documentationとか
