## Constructor

### Point3d

function Point3d (
x:Number, y:Number, z:Number)

Creates 3d point object.
Parameters:
x:
The horizontal coordinate of the point.
y:
The vertical coordinate of the point.
z:
The depth coordinate of the point.

## Class methods

### distance

static function distance (
firstPoint:Point3d, secondPoint:Point3d) : Number

Determines the distance between the first and second points in 3D space.
Parameters:
firstPoint :
The first point.
secondPoint:
The second point.

## Instance methods

### clone

function clone (

Returns:
• A new point object with the same values as this point.

### destroy

function destroy (
) : Void

Overrides:

### equals

function equals (
pointObject:Point3d) : Boolean

Determines whether the point specified in the `pointObject` parameter is equal to this point object.
Parameters:
pointObject:
A defined Point3d object.
Returns:
• Returns `true` if shape's location is identical; otherwise `false`.

### getZ

function getZ (
) : Number

Returns:
• The Z position.

### offset

function offset (
x:Number, y:Number, z:Number) : Void

Offsets the Point object by the specified amount.
Parameters:
x:
The amount by which to offset the horizontal coordinate.
y:
The amount by which to offset the vertical coordinate.
z:
The amount by which to offset the depth coordinate.

### setZ

function setZ (
z:Number) : Void

Sets the Z coordinate.
Parameters:
z:
The depth coordinate of the point.
