Simulates an ASCII art style using a three.js renderer and an SVG mask.
By using a semi transparent SVG mask that doesn't update at runtime frame rate is drastically improved over alternative methods such as the ascii effect example (which was the original inspiration for this project). The limitation of this method is that updating the text or the viewport size is an expensive operation so they can't change often.
Grab ascii-renderer.js or the minified version and set it up according to the
example in index.html. There are code docs in the js.
var renderer = new THREE.WebGLRenderer();
// This step is important, the renderer must have a parent
container.appendChild(renderer.domElement);
var asciiRenderer = new AsciiRenderer(renderer, {
charSet: '010011',
opacity: 0.7,
});Use npm install to set up dependencies. You can start a dev server with
npm run start and minify with npm run start. If you use VS Code
you can also use the shortcut ctrl+shift+B to start the dev server.
- Toon lighting has issues when viewed from behind. Try a custom lighting model.
- Test font ratio detection so that any monospace font can be used.
- Remove unnecessary
<tspan>at the end of the text mask.
