Volumetric Fog

One of the themes we were going for in our animation was that of the looming economic depression. To highlight this in a visual sense we thought it might be nice to render everything in our animation with a covering of fog. We decided in the end that we wouldn't use this effect, becaues it made the animation a little too gloomy, but this is what we did when experimenting.

Maya has special objects which can be created, called Volume Primitives, which can have volumetric shaders applied to them. Using a cube shaped volume primitive, we applied a fog like shader to it, which filled the inside of the cube with three-dimensional fog. The effect was good, as shown in the image below, but as mentioned above was a little too gloomy for our overall animation.
