Figure Legend:
Pixel lighting with box and tent depth filters. The horizontal lines represent two image planes, the thick blue diagonal line the surface we wish to draw, and the thick blue horizontal lines the pixel intensities on the image planes; dark blue represents high intensity and pale blue represents low intensity. The box filter illuminates the far image plane at high intensity for all regions in which the simulated surface is closer to the far than the near plane. It illuminates the near plane at high intensity for all regions in which the simulated surface is closer to that plane. The tent filter weights intensities according to the proportion of the dioptric distance between the two image planes. This occurs along each line of sight. The sum of the two intensities is the same as the intensity on one plane in a conventional display. For details, see Akeley et al. (2004).
