A sprite is a plane that always faces towards the camera, generally with a
|
||
|
|
partially transparent texture applied.<br /><br />
|
||
|
|
|
||
|
|
Sprites do not cast shadows, setting <code>castShadow = true</code> will have no effect.

<h2>Code Example</h2>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
const map = new THREE.TextureLoader().load( 'sprite.png' );
|
||
|
|
const material = new THREE.SpriteMaterial( { map: map } );
|
||
|
|
|
||
|
|
const sprite = new THREE.Sprite( material );
|
||
|
|
scene.add( sprite );
|
||
|
|
</code>
|
||
|
|
|
||
|

<h3>[property:SpriteMaterial material]</h3>

<h3>[property:Vector2 center]</h3>
|
||
|
|
<p>
