    AirSim

    AirSim

    A simulator for drones, cars and more, built on Unreal Engine

    AirSim is an open-source, cross platform simulator for drones, cars and more vehicles, built on Unreal Engine with an experimental Unity release in the works. It supports software-in-the-loop simulation with popular flight controllers such as PX4 & ArduPilot and hardware-in-loop with PX4 for physically and visually realistic simulations. It is developed as an Unreal plugin that can simply be dropped into any Unreal environment. AirSim's development is oriented towards the goal of creating a platform for AI research to experiment with deep learning, computer vision and reinforcement learning algorithms for autonomous vehicles. For this purpose, AirSim also exposes APIs to retrieve data and control vehicles in a platform independent way. AirSim is fully enabled for multiple vehicles. This capability allows you to create multiple vehicles easily and use APIs to control them.

    We do not know the reasons of being abandoned by Ryan in 2018. Fortunately, we have a record which can be traced back to 2017 after figuring out how to obtain in bazaar way COMPLETELY, I translate the revision to git , we might have a chance to ignite again. IF successful, we can do whatever we like. I DO NOT FULLY TRUST AN ENTITY EVEN THAT ENTITY IS OK. SO PLEASE FORK THIS ONE AS SOON AS POSSIBLE ONCE YOU SEE , THE MORE FORKING THE BETTER. IF This helps you, You might consider to help us to get one domain, also try running longer. It is said the consideration might be eye dropping twenty hundred bucks , If you like to, you may contact me for further detail.

    Cambridge Rocketry Simulator

    Simulate high power rocket flights with splash down plots

    This software allows you perform six degree of freedom simulations of High Power Rocket (HPR) and model rocket flights. Parachute descent is also simulated. 3D flight trajectories are produced as well as detailed tabular flight data. Running in Monte Carlo mode allows generates multiple possible flight paths and splash down plots, indicating the probability of landing in an area.

    XCTruck3D _Truck

    realistic truck simulator with 3D graphics done from zero

    A truck/car simulator,with realistic physics and oldstyle graphics: it displays pixels through the SDL graphics routines, or the X11 if using that version (has some issues:so use the SDL ver).While the 3D graphics is done by the program itself without external libraries.The environment is a hilly terrain:total freedom to drive around.A remake of the classic "Terep 2". Written in the C programming language: although the code is 30 pages long, it's simple. Trailer can be detouched pressming 'l' (minuscle ELL) so to drive a normal car. There's an OpenGL version too: see the CTruck3D _Open,and an ASCII-Art ver (Term_ CTruck3D). This is also a good dydactical software: code is easy to undersand,and drawing procedures and physics sim procedure are written from 0 so it's clearly understandable how a complete 3D game is done in C, starting from a blank page of any plain text editor.Only basic knowledge of C was used. VID: http://youtu.be/n_O-9EFW5zk Lagrande_Rally_3D is an evolution of this
