Maple Graphics

The graphics seen on this page was created by myself with the use of a software known as Maple 8.

The picture below looks similar to fluttering Butterfly wings and therefore it got it's name. it was created using the formulae:     This file is saved in the *.gif format.

The next picture was created in VRML format and can be viewed with a programme such as Cortona Player for instance. the formulae used to create this animation is :

VRML image: Small Pox Growth

The above picture was downloaded from the web site: http://www-personal.engin.umich.edu/~kraghava/SmallPox.htm It shows the growth of Small pox of a person's hand.

Small Pox  is a is an acute contagious disease caused by variola virus, a member of the orthopoxvirus family.

Smallpox, which is believed to have originated over 3,000 years ago in India or Egypt, is one of the most devastating diseases known to humanity. For centuries, repeated epidemics swept across continents, decimating populations and changing the course of history.

The disease, for which no effective treatment was ever developed, killed as many as 30% of those infected. Between 65–80% of survivors were marked with deep pitted scars (pockmarks), most prominent on the face.

In the early 1950s – 150 years after the introduction of vaccination – an estimated 50 million cases of smallpox occurred in the world each year, a figure which fell to around 10–15 million by 1967 because of vaccination.

Through the success of the global eradication campaign, smallpox was finally pushed back to the horn of Africa and then to a single last natural case, which occurred in Somalia in 1977. A fatal laboratory-acquired case occurred in the United Kingdom in 1978. The global eradication of smallpox was certified, based on intense verification activities in countries, by a commission of eminent scientists in December 1979 and subsequently endorsed by the World Health Assembly in 1980.
