[page:BufferGeometry] →

# [name]

This can be used as a helper object to view the edges of a [page:Geometry Geometry] object.

## Example

[example:webgl_helpers helpers] `var geometry = new THREE.BoxBufferGeometry( 100, 100, 100 ); var edges = new THREE.EdgesGeometry( geometry ); var line = new THREE.LineSegments( edges, new THREE.LineBasicMaterial( { color: 0xffffff } ) ); scene.add( line );`

## Constructor

### [name]( [param:Geometry geometry], [param:Integer thresholdAngle] )

geometry — Any geometry object.
thresholdAngle — An edge is only rendered if the angle (in degrees) between the face normals of the adjoining faces exceeds this value. default = 1 degree.

## Properties

See the base [page:BufferGeometry] class for common properties.

### [property:Object parameters]

An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.

## Methods

See the base [page:BufferGeometry] class for common methods.
