OpenSCADのビューウィンドウには下記のようなオプションがある。
The surface view is the initial model view that appears when the model code is first rendered.
The Grid Only view presents only the "scaffolding" beneath the surface.  Think of the Eiffel Tower.
This view mode will utilize the open constructive solid geometry library to generating the model view utilizing opengl. If the opencsg library is not available or the video card or drivers do not support opengl, then this view will produce no visible output.
