The DOMMatrix interface represents 4×4 matrices, suitable for 2D and 3D operations including rotation and translation. It is a mutable version of the DOMMatrixReadOnly interface. The interface is available inside web workers.

The DOMMatrixReadOnly interface represents a read-only 4×4 matrix, suitable for 2D and 3D operations. The DOMMatrix interface — which is based upon DOMMatrixReadOnly—adds mutability, allowing you to alter the matrix after creating it.

A DOMPoint object represents a 2D or 3D point in a coordinate system; it includes values for the coordinates in up to three dimensions, as well as an optional perspective value. DOMPoint is based on DOMPointReadOnly but allows its properties' values to be changed.

The DOMPointReadOnly interface specifies the coordinate and perspective fields used by DOMPoint to define a 2D or 3D point in a coordinate system.

A DOMQuad is a collection of four DOMPoints defining the corners of an arbitrary quadrilateral. Returning DOMQuads lets getBoxQuads() return accurate information even when arbitrary 2D or 3D transforms are present. It has a handy bounds attribute returning a DOMRectReadOnly for those cases where you just want an axis-aligned bounding rectangle.

A DOMRect describes the size and position of a rectangle.

The DOMRectReadOnly interface specifies the standard properties (also used by DOMRect) to define a rectangle whose properties are immutable.
