Since CSG was not implemented, I modelled several of the features of the final scene/model here. Below are some water effects and a model that were meant for the final scene.

This is the texture map used for the water effect (available here)

This is the height map I made for it by converting the image into grayscale using Photoshop.

And here is a scene featuring it modelled in a modified Cornell box at a slight angle. The back texture map is used to accentuate the way refraction is affected by the water cube.

Here is the model of the Listerine bottle with texture mapping using non-CSG methods.
