19# modeling-solid-shape-1: Solid Shape : the cutted cube
20
21# Solid shapes are similar to simple shapes, but when they are cut by the camera front,
22# plane the section is drawn, so as they appear as "solid / plain" and not "empty".
23
24# Solid shapes are slower than simple shape, thus you should use them only
25# when the shape is often cut by the camera. They are usefull for light effect, e.g.
26# light cones,...
