Editing Cornell box (section)

=== The Original Cornell Box ===
The original Cornell Box was described by Cindy M. Goral, Kenneth E. Torrance, and Donald P. Greenberg in their 1984 paper titled ''Modeling the Interaction of Light Between Diffuse Surfaces'', presented at SIGGRAPH '84.<ref name="CornellBox1984"/>

In this initial version, the interior was painted in red, blue, and gray, and no occluding objects were placed inside the box. Rather than placing a light source inside, the box was illuminated indirectly using a set of lights and a white diffuse surface.<br>

<!-- Since thumb parameter can't be used in this CSS code: bSize(354px), cWidth(354px), cHeight(360px) and oTop(0px) values have been changed to rescale the image. The code is also pasted before the section, but this way it displays more efficiently because of the <hr> line. -->
