The DOMPoint interface's w property holds the point's perspective value, w, for a point in space.


var perspective = DOMPoint.w;


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 NaN or ±Infinity). The default is 1.0.
