Boolean operation

Boolean geometry operations require the geometry it operates on to be defined:

Property	Type	Description
type	'union', 'intersection', 'difference', 'xor'
condition	formula (optional)
repeat	repeat (optional)
step	boolean, formula (optional)
defs	Definition (optional)
geometry	Geometry	The geometry used in the Boolean operation

Union example

{
  type: "union",
  geometry: [
    { type: "ellipse",
      x: 0.25,
      w: 0.75,
      h: 0.75
    }
    { type: "ellipse",
      y: 0.25,
      w: 0.75,
      h: 0.75
    }
  ]
}

Intersection example

{
  type: "intersection",
  geometry: [
    { type: "ellipse",
      x: 0.25,
      w: 0.75,
      h: 0.75
    }
    { type: "ellipse",
      y: 0.25,
      w: 0.75,
      h: 0.75
    }
  ]
}

Difference example

{
  type: "difference",
  geometry: [
    { type: "ellipse",
      x: 0.25,
      w: 0.75,
      h: 0.75
    }
    { type: "ellipse",
      y: 0.25,
      w: 0.75,
      h: 0.75
    }
  ]
}

XOR example

{
  type: "xor",
  geometry: [
    { type: "ellipse",
      x: 0.25,
      w: 0.75,
      h: 0.75
    }
    { type: "ellipse",
      y: 0.25,
      w: 0.75,
      h: 0.75
    }
  ]
}
