Chapter 78: MeshPhongNodeMaterial

Core Idea

Node material version of MeshPhongMaterial.

isMeshPhongNodeMaterial : boolean (readonly): This flag can be used for type testing.
lights : boolean: Set to true because phong materials react on lights.

Constructor

Signature
`new MeshPhongNodeMaterial( parameters : Object )`

Properties

Property	Description
`.isMeshPhongNodeMaterial : boolean (readonly)`	This flag can be used for type testing.
`.lights : boolean`	Set to `true` because phong materials react on lights.
`.shininessNode : Node.<float>`	The shininess of phong materials is by default inferred from the `shininess` property. This node property allows to overwrite the default and define the shininess with a node instead.
`.specularNode : Node.<vec3>`	The specular color of phong materials is by default inferred from the `specular` property. This node property allows to overwrite the default and define the specular color with a node instead.

Methods

Method	Description
`.setupEnvironment( builder : NodeBuilder ) : BasicEnvironmentNode.<vec3>`	Overwritten since this type of material uses BasicEnvironmentNode to implement the default environment mapping.
`.setupLightingModel() : PhongLightingModel`	Setups the lighting model.
`.setupVariants( builder : NodeBuilder )`	Setups the phong specific node variables.
