Simulation of historical and contemporary launch vehicles
ORT is a tool for modelling and flying launch vehicles of arbitrary size and complexity. Unlike OpenRocket, it does not focus on amateur rockets but on real-world launch vehicles.
The bundle includes a graphical design tool with an integrated simulation engine for rocket launches. Also included in the bundle is a playback application and a headless driver for logging simulations into spreadsheets.
ORT integrates JME3 for 3D rendering.
Jplanets is a simple game for one or two players. Every player has a starship, between the ships there are three planets. The goal is to shoot and destroy the other starship launching a rocket that obey the gravity laws.
