Antialiasing with Three.js appears to be malfunctioning specifically on iPhone 5 and iPhone 5s devices

As a newbie to three.js, I managed to finish my project successfully. To enhance the graphics quality, I decided to enable antialiasing.

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

Unfortunately, after enabling antialiasing on iPhone 5 and iPhone 5s devices, the renderer ceased to function.

  • iPhone 5 runs on iOS version 9.2.1
  • iPhone 5s operates on iOS version 7.1.2
  • The browser being used is Safari

Is there a way to disable antialiasing specifically for these devices? How can I resolve this issue?

Answer №1

Dealing with performance issues on iPhones can be tricky, especially when it comes to antialiasing on retina displays. While high-density displays already have built-in antialiasing, sometimes there may still be issues that need to be addressed. One way to tackle this problem is by adjusting the renderer settings like so:

var devicePixelRatio = window.devicePixelRatio || 1;
var renderer = new THREE.WebGLRenderer({antialias: devicePixelRatio === 1});
