• Generates C++ code
• Written in Java (needs JDK 1.2)

Helpful Links

• To use the GPE you need to have Java installed on your machine and download GPE.jar from http://erpc1.naruto-u.ac.jp/~geant4/index.html
setenv CLASSPATH./GPE.jar
java -green gpe
• Look at slide number 24 to see an example of the main panel.
• To see an example of the particle panel, see slide number 25.
