Examples of javax.media.j3d.Material

javax.media.j3d.Material
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.
