    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.

    CTruck3D _Open

    realistic truck & car simulator, with OpenGL graphics

    update: https://sourceforge.net/projects/newctruck3drally/ It's a 3D, physically realistic truck/car simulator, oriented to dirt tracks. This is subsancially kept as hystorical. The environment is a hilly terrain which can also be user-defined in the form of a Bitmap image file (where intensity of red component defines height). It's similar to the classic "Terep 2". Particular care for internal cam. Written in standard C. There's a Windows executable ready for use, but it's compilable and playable on all Linux, BSD, MacOSX systems. Official VIDEO presentation: http://www.youtube.com/watch?v=B74QvPGyBYM The physical simulation was written from 0 of course, so no external 'third-party' libraries are used; except GLUT+OpenGL for the graphical visualisation & good interactivity.

    skunks

    skunks

    3D driving simulation based on Open Dynamics Engine

    Sour*eforge.net has become inaccesible to me because of Cl*udflare. The latest version of skunks is on my site: https://matei.one/. 3D realistic driving (not racing) simulation with software rendering, based on Open Dynamics Engine (which is included in all *.tar.gz files so it doesn't have to be downloaded separately). 10 cars (all electric) and 16 tracks are available in version 5.1.0. Cars and tracks can be easily created and modified. Only SDL 1.2 or SDL 2 required besides standard C library. GNU/Linux and Wind0ws executables are available. If using GNU/Linux and SDL 2, it might be necessary to add -lpthread in the comp file, at line 2.

    a collection of small and medium-sized simulation programs that I made explicitely for dydactic and/or documentation purposes. Browse the files, don't click on widnload because there are multiple zips!! All are related to rigidbody dynamics used to make vehicle simulators in the simplest way. Other types of programs may figure too: Snake or Tetris in C for showing the C programming style opted for the other, more specific programs. Possibly this is a link for supplying material to some Wiki articles related to videogames and gamep-physics.
