Abstract:
Many publications on rendering at some point make reference to a theoretical or ideal pinhole camera model, the implication being that an infinitely small hole will produce a perfectly sharp image. However this is not the case. The assumptions of ray, and particle based models of light transport do not accurately represent the results obtained from small aperture systems. Here we consider a more appropriate model, which is capable of reproducing the results of a real pinhole camera, and in doing so generate an interesting interpretation of diffraction, as a sampling artifact.
