#### Intersection

The `intersection` object creates a shape containing only those areas where all components overlap. A point is part an intersection if it is inside both objects, `A` and `B`, as show in the figure below.

The intersection of two objects.

The syntax is:

INTERSECTION:

`
  intersection {
` SOLID_OBJECTS... [OBJECT_MODIFIERS...] `}`

The component objects must have well defined inside/outside properties. Patch objects are not allowed. Note that if all components do not overlap, the intersection object disappears.

Here is an example that overlaps:

      intersection {

        box { <-1.5, -1, -1>, <0.5, 1, 1> }

        cylinder { <0.5, 0, -1>, <0.5, 0, 1>, 1 }

      }
