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 { 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 }
