Instance Method Details

#between?(point1, point2, on_point = true) ⇒ Boolean

Checks if a point is on line between two other points.

point1 and point2 should be a Geom::Point3d, Array object, or and object that implements a .position method that returns a 3d position.

When on_point is true the method will return true if self is equal to point1 or point2.

Parameters:

  • point1 (Geom::Point3d|Mixed)
  • point2 (Geom::Point3d|Mixed)
  • on_point (Boolean) (defaults to: true)

Returns:

  • (Boolean)

Since:

  • 2.5.0

  # (!) May return  different hash for identical positions.

  #[self.x, self.y, self.z].hash
  # (!) Experimental!
  # Convert X, Y and Z to ints at 1000th accuracy to avoid inconsistent hash
  # values for identical positions.
