EdgeSplitModifier

The modifier can be used to split faces at sharp edges. This allows to compute normals without smoothing the edges which can lead to an improved visual result.

Code Example

const modifier = new EdgeSplitModifier();
geometry = modifier.modify( geometry, Math.PI * 0.4 );

Import

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

import { EdgeSplitModifier } from 'three/addons/modifiers/EdgeSplitModifier.js';

Constructor

new EdgeSplitModifier()

Methods

.modify( geometry : BufferGeometry, cutOffAngle : number, tryKeepNormals : boolean ) : BufferGeometry

Returns a new, modified version of the given geometry by applying an edge-split operation. Please note that the resulting geometry is always indexed.

geometry

The geometry to modify.
cutOffAngle

The cut off angle in radians.
tryKeepNormals

Whether to try to keep normals or not.

Default is true.
Returns: A new, modified geometry.
