Class Material

    java.lang.Object

          javax.media.j3d.NodeComponent
              javax.media.j3d.Material

    public class Material

extends NodeComponent

The Material object defines the appearance of an object under illumination. If the Material object in an Appearance object is `null`, lighting is disabled for all nodes that use that Appearance object.

The properties that can be set for a Material object are:

- Ambient color - the ambient RGB color reflected off the surface of the material. The range of values is 0.0 to 1.0. The default ambient color is (0.2, 0.2, 0.2).

- Diffuse color - the RGB color of the material when illuminated. The range of values is 0.0 to 1.0. The default diffuse color is (1.0, 1.0, 1.0).

- Specular color - the RGB specular color of the material (highlights). The range of values is 0.0 to 1.0. The default specular color is (1.0, 1.0, 1.0).

- Emissive color - the RGB color of the light the material emits, if any. The range of values is 0.0 to 1.0. The default emissive color is (0.0, 0.0, 0.0).

- Shininess - the material's shininess, in the range [1.0, 128.0] with 1.0 being not shiny and 128.0 being very shiny. Values outside this range are clamped. The default value for the material's shininess is 64.

- Color target - the material color target for per-vertex colors, one of: AMBIENT, EMISSIVE, DIFFUSE, SPECULAR, or AMBIENT_AND_DIFFUSE. The default target is DIFFUSE.

The Material object also enables or disables lighting.
