Antialiasing not working in Three.js

Question

I am new to three.js and have starting working with it a lot recently. I really enjoy it and I have created some incredible things. However, I'm unsure why but when setting antialiasing to true I see no difference.

 renderer = new THREE.WebGLRenderer({ antialiasing: true });

I have searched for possible solutions, yet I can't seem to find or understand why this doesn't work. Is there something I am missing or need to in order to get antialiasing to work?

EDIT:

Links that helped me fix this issue: https://github.com/mrdoob/three.js/blob/master/examples/webgl_materials_normalmap2.html https://github.com/mrdoob/three.js/tree/master/examples/js

It took some digging but the developers for three.js have it covered!

Answer 1

The property name you are using in the argument object of the WebGLRenderer constructor is incorrect. According to the documentation, the name of the property should be 'antialias', not 'antialiasing'.

I tested it in Google Chrome for Mac OS and there was a noticeable smoothing in the rendering of edges in a demo featuring a spinning cube.

Answer 2

The property is called antialias and It is activated like this:

renderer = new THREE.WebGLRenderer({ antialias: true });

Doesn't work for all browsers, check this issue for more information.

Note:
The property is NOT publicly accessible, so setting antialias after construction like this:

renderer.antialias = true; // <-- DOES NOT WORK

will not work.

Answer 3

In case your computer does not support default WebGL AA, resizing the renderer size and canvas width gives me much better result than FXAA. Mind you the CSS holds the real width and height values.

var w,h = [your prefs];

renderer.setSize(window.innerWidth*2, window.innerHeight*2);

renderer.domElement.style.width = w;
renderer.domElement.style.height = h;
renderer.domElement.width = w*2
renderer.domElement.height = h*2

Answer 4

renderer = new THREE.WebGLRenderer( { antialias: true } );

The above works with my desktop computer, but it doesn't seem to work with my laptop.
