A model's material with modifiable parameters. A glTF material
contains parameters defined by the material's technique with values
defined by the technique and potentially overridden by the material.
This class allows changing these values at runtime.
Use Model#getMaterial
to create an instance.

Methods
Returns the value of the parameter with the given
name
. The type of the
returned object depends on the glTF type of the parameter. It will be a floating-point
number, Cartesian, or matrix.
Name | Type | Description |
---|---|---|
name |
String | The name of the parameter. |
Returns:
The value of the parameter or
undefined
if the parameter does not exist.
Assigns a value to a material parameter. The type for

material.setValue('shininess', 256.0); // scalar
