Sets the reflectance properties of surfaces and patches.

Category: Graphics > Formatting and Annotation

Syntax

material shiny

Strong specular highlights that take the color of the light.

material dull

No specular highlight, mostly diffuse reflection.

material metal

Strong specular highlight that takes the color of the surface.

material default

Restores the default values.

material([ka kd ks n sc])

Sets the five parameters directly.

Description

The setting changes the AmbientStrength, DiffuseStrength, SpecularStrength, SpecularExponent and SpecularColorReflectance properties of every surface and patch in the axes. A larger specular exponent makes the highlight smaller and sharper.

Like all lighting settings it has a visible effect only when a light is present in the axes.

Input arguments

[ka kd ks n sc]: Ambient, diffuse and specular strength, specular exponent and specular color reflectance.

Example

Shiny sphere

s = surf(sphere(40));
shading interp
lighting gouraud
camlight
material shiny
s.SpecularExponent

Output

ans = 10
