Root-based simulator for ray tracing (ROBAST) is a non-sequential ray tracing program which utilizes the 3D geometry library in ROOT. Its function is very simple compared to Geant4 Optical, but much easier to use.
ROBAST is designed for ROOT users who would like to simulate a cosmic-ray or gamma-ray telescope which requires only geometrical optics.
Introductory document is available at http://arxiv.org/abs/1110.4448
(a full ROBAST paper is coming in 2015).
