Getting Started with iGeo

Install Processing

Please have Processing installed. Currently iGeo works on Processing version 2.1.1, version 2.0.3 and version 1.5.1. If you have a problem around OpenGL and a graphic card in Processing 2.0 or later, please try processing stable version 1.5.1 and iGeo library for Processing 1.5. For download and installation of Processing, please see Processing's download page.

Install iGeo

1.     To install iGeo library, download an installation file at the download page and put the downloaded igeo.zip file inside the "libraries" folder under the location of Processing's sketchbook, and unzip the file there.
Default locations of "libraries" folder under Processing's sketchbook are like below.

Default location in Windows

My Documents\Processing\libraries\

Default location in Mac

~/Documents/Processing/libraries/

When it's unzipped, sub folders of "igeo/library/" is created automatically and the JAR file should be located like below.

...../Processing/libraries/igeo/library/igeo.jar

2.     Restart Processing.

3.     It's successful if you can see "iGeo" at the menu "Sketch" > "Import Library..."

For more information about the installation of a library please see "How to Install a Contributed Library" at processing.org.

Importing Library

1.     Import iGeo library by the menu "Sketch" > "Import Library..." > "iGeo".

2.     If you are using Processing stable version 1.5, import also OpenGL library by the menu "Sketch" > "Import Library..." > "OpenGL". In Processing 2.0 or later, you don't need to import OpenGL.

Or, simply you can type these two lines in the beginning of the code.

import processing.opengl.*;
import igeo.*;

3.     Now you are ready to code. Have fun coding with iGeo.

Please go ahead to see other tutorial pages to start writing example codes.
