It was a nice way to teach myself OpenGL basics with complex 3D objects (spheres), and simple transforms. The code is shared as an example basis for those learning OpenGL; as I did.**\n\n![Callisto - Yet another Solar System simulator](https://valeriansaliou.github.io/callisto/images/solar-system-simulator.jpg)\n\n## Dependencies\n\n * **Go** (install it via: `brew install golang` on MacOS w/ Homebrew)\n * **OpenGL headers** and **GLFW headers** (built-in on MacOS)\n\nAlso, check that your `$GOPATH` is configured, and that `$GOPATH/bin` is sourced in your `$PATH`.\n\n### MacOS\n\nShould work out of the box.\n\n### Linux (Ubuntu, Debian)\n\nInstall the necessary utilities and libraries:\n\n`sudo apt-get install git libglfw-dev libxrandr-dev libxcursor-dev libxinerama-dev libxi-dev`\n\n## Install \u0026 Run\n\n 1. `go get github.com/valeriansaliou/callisto`\n 2. `callisto`\n\n## Controls\n\n * **Direction**\n  * `UP` `DOWN` `LEFT` `RIGHT`: move camera position\n  * `Mouse move`: move camera target\n\n * **Camera**\n  * `R`: reset camera position\n  * `SPACE`: turbo camera move (hold key)\n\n * **Simulation**\n  * `Scroll UP` `Scroll DOWN`: decrease/increase simulation speed\n\n * **Application**\n  * `ESCAPE`: exit Callisto\n\n## Disclaimer\n\nDistances and radiuses, as well as rotation/revolution periods have been respected. Since both the Sun, Jupiter and Saturn are quite huge relative to other Solar System objects, a square-root factor has been applied on all radiuses and distances. This makes huge objects smaller on display, and small objects visible on display.\n\n## Thanks\n\nThis project has been achieved following the excellent step-by-step tutorial available on [https://open.gl](https://open.gl)\n\n## Copyrights\n\nAssets (planets, moons, miscellaneous space object) are copyright NASA.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvaleriansaliou%2Fcallisto","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fvaleriansaliou%2Fcallisto","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvaleriansaliou%2Fcallisto/lists"}
