DOMPointReadOnly: w property

{{APIRef("Geometry Interfaces")}}{{AvailableInWorkers}}

The DOMPointReadOnly interface's w property holds the point's perspective value, w, for a read-only point in space.

If your script needs to be able to change the value of this property, you should instead use the {{domxref("DOMPoint")}} object.

Value

A double-precision floating-point value indicating the w perspective value for the point. This value is unrestricted, meaning that it is allowed to be infinite or invalid (that is, its value may be {{jsxref("NaN")}} or {{jsxref("Infinity", "±Infinity")}}). The default is 1.0.
