DecalGeometry

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.

Please not that decal projections can be distorted when used around corners. More information at this GitHub issue: Decal projections without distortions.

Reference: How to project decals

Code Example

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 );

Import

DecalGeometry is an addon, and must be imported explicitly, see Installation#Addons.

import { DecalGeometry } from 'three/addons/geometries/DecalGeometry.js';

Constructor

new DecalGeometry( mesh : Mesh, position : Vector3, orientation : Euler, size : Vector3 )

Constructs a new decal geometry.

mesh	The base mesh the decal should be projected on.
position	The position of the decal projector.
orientation	The orientation of the decal projector.
size	The scale of the decal projector.
