I had some grand plans for the application, but they were never realised so it's probably more useful to just release it as it is for others to take a look! There are plenty of issues with it and it's pretty rough having been developed over 2 years ago now, but if it's some use to anyone that's great. Example at https://alexanderperrin.com.au/triangles/ballooning. Use the arrow keys or the left and right sides of the screen on touch devices to move the balloon. ## Features - Procedurally generated infinite terrain & tree placement - Happy flapping birds - Shoreline boathouse placement - Pleasant mountain ballooning - Statically batched tree rendering - Runs on desktop and mobile ## Development Feel free to have a dig around in the code and change things. I've setup a [webpack](https://webpack.js.org/) development environment with hot module replacement that you can use to quickly iterate the application. - Ensure that you have node and npm installed on your machine. You can follow the official instructions at https://www.npmjs.com/get-npm - Clone the repository into your desired project folder - Run `npm install` from within the project folder to install dependencies - Ensure webpack-cli is either available globally or installed locally (`npm install --save-dev webpack-cli`) - Run `npm start`. This will spin up a webpack development server running at http://localhost:8080 - Change the code you like and see what happens! ## Building - Run `npm run build` to build a production ready version of the web app. - Contents will be processed into /dist, which you can upload to your web server. ## License MIT ## Warranty None whatsoever. ================================================ FILE: bundle.js ================================================ /******/ (function(modules) { // webpackBootstrap /******/ // The module cache /******/ var installedModules = {}; /******/ // The require function /******/ function __webpack_require__(moduleId) { /******/ // Check if module is in cache /******/ if(installedModules[moduleId]) /******/ return installedModules[moduleId].exports; /******/ // Create a new module (and put it into the cache) /******/ var module = installedModules[moduleId] = { /******/ exports: {}, /******/ id: moduleId, /******/ loaded: false /******/ }; /******/ // Execute the module function /******/ modules[moduleId].call(module.exports, module, module.exports, __webpack_require__); /******/ // Flag the module as loaded /******/ module.loaded = true; /******/ // Return the exports of the module /******/ return module.exports; /******/ } /******/ // expose the modules object (__webpack_modules__) /******/ __webpack_require__.m = modules; /******/ // expose the module cache /******/ __webpack_require__.c = installedModules; /******/ // __webpack_public_path__ /******/ __webpack_require__.p = ""; /******/ // Load entry module and return exports /******/ return __webpack_require__(0); /******/ }) /************************************************************************/ /******/ ([ /* 0 */ /***/ function(module, exports, __webpack_require__) { __webpack_require__(1); (function webpackMissingModule() { throw new Error("Cannot find module \"run\""); }()); (function webpackMissingModule() { throw new Error("Cannot find module \"dev\""); }()); /***/ }, /* 1 */ /***/ function(module, exports, __webpack_require__) { /* WEBPACK VAR INJECTION */(function(THREE) {'use strict'; var _Detector = __webpack_require__(3); var _Detector2 = _interopRequireDefault(_Detector); var _player = __webpack_require__(5); var _player2 = _interopRequireDefault(_player); var _terrainPatch = __webpack_require__(7); var _terrainPatch2 = _interopRequireDefault(_terrainPatch); var _heightmap = __webpack_require__(8); var _heightmap2 = _interopRequireDefault(_heightmap); var _bird = __webpack_require__(10); var _bird2 = _interopRequireDefault(_bird); var _mathf = __webpack_require__(6); var _mathf2 = _interopRequireDefault(_mathf); var _jquery = __webpack_require__(11); var _jquery2 = _interopRequireDefault(_jquery); function _interopRequireDefault(obj) { return obj && obj.__esModule ?
