Generating virtual shadows for displayable elements
Abstract:
A computing device can present a plurality of displayable elements, some of which appear to be on top of or overlaying others. The computing device can determine which displayable elements should cast virtual shadows on which other displayable elements based, at least in part, on a respective virtual depth value associated with each of the displayable elements. In general, a displayable element with a higher depth value can cast a shadow on a displayable element with a lower depth value. The device can select a first displayable element for which a virtual shadow is to be generated. The device can acquire a graphical representation of the first displayable element. The computing device can then apply a blurring technique, a color filtering process, and a transparency filtering process to the graphical representation to generate a virtual shadow for the first displayable element. Then the device can draw or display the shadow.
