Final stage of the Portugal SURFER competition
There is still more than one week left to participate in the ongoing SURFER picture competition, so start being creative and upload your images! The competition, that started already on May 18, 2012 will run until April 28, 2013. Then a judging panel will decide about the winners of the competition.
Algebraic surfaces are produced by simple equations in three spatial coordinates x,y,z. All points which satisfy these equations are drawn. With SURFER, images of algebraic surfaces are easily generated. You will find the program for download and a guidance manual on the SURFER page.
The competition requires creativity, intuition and mathematical skill in order to create equations yourself or to change given equations to produce beautiful images. To participate in the competition, create an image with SURFER, save it as a png file and then upload it on the competition homepage (which is only available in Portuguese – just click on the “Enviar Imagem” item to submit your picture).
