IMAGE DESCRIPTION:

This image is a tribute to Leonardo Da Vinci. A man who was a physicist, before there were
physicists, and a mathematician of true genious. The render is of the invention that IMO best
represents his talents in these two fields ; The Da Vinci Helicopter.

DESCRIPTION OF HOW THIS IMAGE WAS CREATED:

As the original sketch for the Da Vinci helicopter was exactly that, a sketch and not a
resolved design, I decided to apply the same restrictions on the render. The model of the
helicopter is very sketchy, and there are some areas that are unresolved. The room in which the
helicopter is placed is also unresolved in detail. Another feature of the image is the
primarily monochromatic pallet.

The helicopter spiral blade was created using a DeJong Box. I grabbed the original DeJong Box
file from the POVray CD rom and upgraded the code to POV3 syntax. The rest of the image 
modelling is very simple. A classical room (roughly of the same time as Da Vinci) was created
using my Column Plugin and drafted in Autocad.

Finally the image was rendered using an atmospheric effect to give depth and texture to the
image along with some standard radiosity settings to give form to the architectural relief.
Also note the use of a carefully placed mirror to make the corridor to the left look longer 
without having to model it the entire length.
