The Fast & Realistic OpenGL Displayer (FROG) is a generic framework dedicated to visualize events in a given geometry.

FROG has been firstly written by Loïc Quertenmont and Vincent Roberfroid in order to view, in a matter of seconds, events in the Compact Muon Solenoid detector.

This detector is located at CERN and is dedicated to measure emitted particles produced by the collisions of high energetic protons accelerated by the Large Hadron Collider.

Moreover, in comparison with the 2 other event displayers, FROG is very light and very fast and can run on various Operating System (Windows, Linux, Mac OS).

In addition, FROG is self-consistent and does not require installation of big libraries generally used by High Energy physic experiments such as ROOT.
