EdgesGeometry

Can be used as a helper object to view the edges of a geometry.

Note: It is not yet possible to serialize/deserialize instances of this class.

Code Example

const geometry = new THREE.BoxGeometry();
const edges = new THREE.EdgesGeometry( geometry );
const line = new THREE.LineSegments( edges );
scene.add( line );

Constructor

new EdgesGeometry( geometry : BufferGeometry, thresholdAngle : number )

Constructs a new edges geometry.

geometry | The geometry. Default is null.
---|---
thresholdAngle | An edge is only rendered if the angle (in degrees) between the face normals of the adjoining faces exceeds this value. Default is 1.

Properties

.parameters : Object

Holds the constructor parameters that have been used to generate the geometry. Any modification after instantiation does not change the geometry.
