// Cloned by Michael Walsh on 29 Nov 2022 from World "ASCII" by Three.js porting demo 
// Please leave this clone trail 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
