Abstract: An apparatus and method for 3D rendering of a canvas and at least a first background in a ZUI environment are disclosed herein. Within a viewing window, display at least a portion of the canvas and at least a portion of the first background in parallax. Receive a user action taken on the viewing window that triggers a change in the displaying of the canvas and the first background. Calculate a first transform value and a first transparency value for the first background, in response to the received user action. Update the display of the canvas and the first background in response to the received user action, the canvas updated in accordance with the received user action and the first background updated in accordance with the first transform value and the first transparency value.
