    • Cylinder

      public Cylinder​(Material material, Ray ray, double radius, double height)
      This constructs a Cylinder.
      Parameters:
      material - The Material the cylinder is made from.
      ray - The ray that makes up the center of the Cylinder.
      radius - A positive double that represents the radius.
      height - A positive double that represents the height of the Cylinder.
      Throws:
      java.lang.IllegalArgumentException - if the radius is zero or the height is not positive.

    • normal

      public NormalizedVector normal​(Point p)
      This function returns the normal vector relative to the Point p. p is assumed to be on the surface of the Cylinder. Anything else is undefined behavior.
      Specified by:
      normal in class Geometry
      Parameters:
      p - The point at which to find the normal vector.
      Returns:
      A NormalizedVector perpendicular to the surface of the shape at the given Point.

    • intersect

      public java.util.List<Intersection> intersect​(LineSegment line)
      Description copied from interface: Intersectible
      Calculates all the intersections between a given LineSegment and this object.
      Parameters:
      line - The LineSegment to check for intersections.
      Returns:
      A list of all the intersections with the given LineSegment.

    • boundary

      public geometries.Boundary boundary()
      Description copied from interface: Intersectible
      Get the Boundary of this intersectible.
      Returns:
      The bounding box of this intersectible.
