Abstract

FROG is a generic framework dedicated to visualisation of events in high energy experiment. It is suitable to any particular physics experiment or detector design. The code is light (<3 MB) and fast (browsing time ~20 events per second for a large High Energy Physics experiment) and can run on various operating systems, as its object-oriented structure (C++) relies on the cross-platform OPENGL and GLUT libraries. Moreover, FROG does not require installation of third party libraries for the visualisation. This document describes the features and principles of FROG version 1.106, its working scheme and numerous functionalities such as: 3D and 2D visualisations, graphical user interface, mouse interface, configuration files, production of pictures of various format, integration of personal objects, etc. Finally, several examples of its current applications are presented for illustration.
