// template is blank
// define your own Three.js World here
// Port of ASCII example:
// https://threejs.org/examples/#webgl_effects_ascii
// Unusually among the three.js examples, screenshot will actually be of a HTML area, not of a WebGL canvas
// So use "Web page" API, with a "grab HTML" screenshot library, not a "grab canvas" screenshot library
// Uses JS Module form of Three.js library
// load CSS (do everything from JS)
AB.loadCSS ( '/uploads/threeport/main.css' );
// edit paths to JS
