VertexNormalsHelper

THREE.VertexNormalsHelper
See theVertexNormalsHelper companion object
class VertexNormalsHelper(`object`: Object3D, var size: Double, var color: Double | Color | String) extends LineSegments

Visualizes an object's vertex normals.

Requires that normals have been specified in the geometry as a buffer attribute or have been calculated using BufferGeometry#computeVertexNormals.

Attributes

Example 
 val geometry = new BoxGeometry(10, 10, 10, 2, 2, 2)
 val material = new MeshStandardMaterial()
 val mesh     = new Mesh(geometry, material)
 scene.add(mesh)
 val helper = new VertexNormalsHelper(mesh, 1, 0xff0000)
 scene.add(helper)
