<h2>代码示例</h2>
|
||
|
||
<code>
|
||
const light = new THREE.PointLight( 0xffffff, 1.5, 2000 );
|
||
|
||
const textureLoader = new THREE.TextureLoader();
|
||
|
||
const textureFlare0 = textureLoader.load( "textures/lensflare/lensflare0.png" );
|
||
const textureFlare1 = textureLoader.load( "textures/lensflare/lensflare2.png" );
|
||
const textureFlare2 = textureLoader.load( "textures/lensflare/lensflare3.png" );
|
||
|
||
const lensflare = new Lensflare();
|
||
|
||
lensflare.addElement( new LensflareElement( textureFlare0, 512, 0 ) );
|
