Bokeh / Depth Of Field

To provide a more realistic look for you applications, Gorilla3D supplies a simple to use Bokeh (or Depth Of Field) component.

In photography, bokeh (/ˈboʊkə/ BOH-kə or /ˈboʊkeɪ/ BOH-kay;[1] Japanese: [boke]) is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens.[2][3][4] Bokeh has been defined as "the way the lens renders out-of-focus points of light".[5] Differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting ("good" and "bad" bokeh, respectively).[6] Bokeh occurs for parts of the scene that lie outside the depth of field. Photographers sometimes deliberately use a shallow focus technique to create images with prominent out-of-focus regions. Bokeh is often most visible around small background highlights, such as specular reflections and light sources, which is why it is often associated with such areas.[6] However, bokeh is not limited to highlights; blur occurs in all out-of-focus regions of the image.
