Bloom blend effect for three.js.
This effect relies on THREE.EffectComposer.
var composer = new THREE.EffectComposer();
composer.addPass(new THREE.RenderPass(scene, camera));
var bloomPass = new THREE.BloomBlendPass(
2.0, // the amount of blur
1.0, // interpolation(0.0 ~ 1.0) original image and bloomed image
new THREE.Vector2(1024, 1024) // image resolution
);
bloomPass.renderToScreen = true;
composer.addPass(bloomPass);
composer.render();
