PhongMaterial

A material class specifies reflection properties of a shiny surface, uses Blinn-Phong model for underlying implementation.

Usage

Create a material class

const phongMaterial = new PhongMaterial({
  ambient: 0.2,
  diffuse: 0.5,
  shininess: 32,
  specularColor: [255, 255, 255]
});

Methods

constructor

The constructor for the PhongMaterial class. Use this to create a new PhongMaterial.

const phongMaterial = new PhongMaterial({ambient, diffuse, shininess, specularColor});

• ambient - (number,) Ambient light reflection ratio, default value is 0.4.
• diffuse - (number) Diffuse light reflection ratio, default value is 0.6.
• shininess - (number) Parameter to control specular highlight radius, default value is 32.
• specularColor - (array) Color applied to specular lighting, default value is [255, 255, 255].
