DOMPointReadOnly - Web APIs
the dompointreadonly interface specifies the coordinate and perspective fields used by dompoint to define a 2d or 3d point in a coordinate system.
... there are two ways to create a new dompointreadonly instance.
... first, you can use its constructor, passing in the values of the parameters for each dimension and, optionally, the perspective: /* 2d */ const point = new dompointreadonly(50, 50); /* 3d */ const point = new dompointreadonly(50, 50, 25); /* 3d with perspective */ const point = new dompointreadonly(100, 100, 100, 1.0); the other option is to use the static dompointreadonly.frompoint() method: const point = dompointreadonly.frompoint({x: 100, y: 100, z: 50; w: 1.0}); constructor dompointreadonly() creates a new dompointreadonly object given the values of its coordinates and perspective.
