JSURFER - VISUALIZATION OF ALGEBRAIC SURFACES MAC BUNDLE
--------------------------------------------------------

GENERAL
A programme developed by the Mathematisches Forschungsinstitu Oberwolfach in co-operation with the University Halle, Germany. jSurfer is part of the traveling math art exhibition IMAGINARY, see www.imaginary-exhibition.com.

Note: jSurfer is a Java alternative of the programme Surfer written in C. Surfer offers more options and information, especially sample galleries, extended ray tracing or resolution settings and options to create videos. Surfer is available under a open source license for Linux systems and Windows (a Mac version is available via Fink) at:

INSTALLATION
Just start the jSurfer.app (drag it into your application folder or on your dock).

HOW TO USE JSURFER
Algebraic surfaces are produced by simple equations in three spatial coordinates x,y,z. All points which satisfy these equations are drawn. For example, the equation x2 + y2 + z2 = 1 results in a sphere.
In the formula field on the bottom you can enter your algebraic equation. If the syntax of the formula is incorrect, the form field is displayed in red and no surface is shown. Turn the surface in space by dragging it with our mouse. With the mouse wheel or the up/down keys you can zoom in and out (the clipping sphere is becoming smaller or bigger). On the right side you can choose colours for the front or backside of the surface. With the "save image" button a png file in resolution 1024x1024 can be saved on your computer.
We are collecting the most beautiful surfaces and organize SURFER picture competitions with prizes, please see our IMAGINARY website www.imaginary-exhibition.com or our Facebook page www.facebook.com/imaginary.exhibition for ongoing activities.
