Types

type Material

type Material struct {
	// The Color of the material. Default: white
	Color color.Color
	// The Ambient reflection of the material. Range is [0, 1]. Default is 0.1.
	Ambient float64
	// The Diffuse reflection of the material. Range is [0, 1]. Default is 0.9
	Diffuse float64
	// The Specular reflection of the material. Range is [0, 1]. Default is 0.9
	Specular float64
	// The Shininess of the material. Range is [10, 200]. Default is 200.0
	Shininess float64
}

Material represents a material on the surface of an object. It uses the Phong reflection model to simulate the reflection of light.

func NewDefaultMaterial

func NewDefaultMaterial() *Material

NewDefaultMaterial returns a new Material with default values.

func NewMaterial

func NewMaterial(c color.Color, ambient, diffuse, specular, shininess float64) *Material

NewMaterial returns a new Material having the passed values.
