Constructor Detail

FresnelSpecularMethod

()

Constructor

public function FresnelSpecularMethod(basedOnSurface:Boolean = true, baseSpecularMethod:BasicSpecularMethod = null)

Creates a new FresnelSpecularMethod object.

Parameters

	`basedOnSurface:Boolean` (default = `true`) — Defines whether the fresnel effect should be based on the view angle on the surface (if true), or on the angle between the light and the view.

	`baseSpecularMethod:BasicSpecularMethod` (default = `null`)
