Simulating a window requires the creation of an outdoor scene. Windauga tested various configurations of images. Only full 3D images succeeded in creating the feeling of a real window. Various details were optimized to enhance the depth of the system. Windauga also found that the most appealing images are not simple landscape photographs,but full 3D systems,mixing 3D images and physical elements on the inner side of the window.

Windauga scenes combine remote scenes and neighbouring elements. These are for instance building components such as window posts,lintels or sills, which can be made of wood, masonry or bricks. They could also be tree branches, plants, or objects located near the window.

Daylight varies in intensity and colour. Such variations can be simulated using various processes. At least two light sources of different colours are necessary. Windauga proposes to use up to 4 channels of coloured light able to simulate daylight, sunlight, clouds, blue sky, sunset,haze , reflexions on water, etc.


The time dimension was found to be essential, not only because it makes sense that light coming through a window varies, but mainly because careful continuous recording of real daylight variations with spectrophotometers demonstrated the subtle fluctuations of light and colour over time.
