				<div class="class-description"><p>This class can be used to create a decal mesh that serves different kinds of purposes e.g.
adding unique details to models, performing dynamic visual environmental changes or covering seams.</p>
<p>Please not that decal projections can be distorted when used around corners. More information at
this GitHub issue: <a href="https://github.com/mrdoob/three.js/issues/21187" target="_blank" rel="noopener">Decal projections without distortions</a>.</p>

				<h2>Code Example</h2>
				<div translate="no"><pre><code class="language-js">const geometry = new DecalGeometry( mesh, position, orientation, size );
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
const mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );
