The Cornell Program of Computer Graphics has become best known
for its research on physically based rendering.
We believe that computer graphics simulations
will never become predictive of reality unless
we correctly model the physics of light reflection
and light energy propagation within physical environments.
The Cornell Box experiments
have come to symbolize our approach to physically based rendering.
The Cornell box is a simple physical environment
for which we have measured the lighting, geometry,
and material reflectance properties.
Synthetic images of this environment are then created,
and compared to images captured with a calibrated CCD camera.
In this way, we can confirm the accuracy of our simulations.

History |
The box has been used for many experiments over the years,
and has changed to adapt to the needs of our researchers.

Comparison |
See an example of how synthetic images of the box are
compared with photographs of the real thing.

Data |
Specifications of the geometry and material properties of the box
are provided for public use.
