## javax.media.j3d
Class ShaderAppearance

    java.lang.Object
      javax.media.j3d.SceneGraphObject
          javax.media.j3d.NodeComponent
              javax.media.j3d.Appearance
                  javax.media.j3d.ShaderAppearance

    public class ShaderAppearance

extends Appearance

The ShaderAppearance object defines programmable shading attributes that can be set as a component object of a Shape3D node. The ShaderAppearance rendering state adds the following attributes in addition to those defined by Appearance:

- Shader program - specifies the shader program...

- Shader attribute set - specifies the shader parameters, both as explicit attributes and as implicit bindings to Java 3D state...

The ShaderAppearance object modifies the definition of some of the attributes in Appearance:

- Coloring attributes - XXXXX

- Line attributes - XXXXX

- Point attributes - XXXXX

- Polygon attributes - XXXXX

- Rendering attributes - XXXXX

- Transparency attributes - XXXXX

- Material - XXXXX

- Texture - XXXXX

- Texture attributes - XXXXX

- Texture coordinate generation - XXXXX

- Texture unit state - XXXXX

Since:
  Java 3D 1.4

Constructor Detail

### ShaderAppearance

    public ShaderAppearance()

  Constructs a ShaderAppearance component object using defaults for all state variables. All component object references are initialized to null.

Method Detail

### setShaderProgram

    public void setShaderProgram(ShaderProgram shaderProgram)

  Sets the ShaderProgram object to the specified object. Setting it to null causes a default pass-through shader to be used ???

  Parameters:
    `shaderProgram` - object that specifies the desired shader program
  Throws:
    `CapabilityNotSetException` - if appropriate capability is not set and this object is part of live or compiled scene graph

### getShaderProgram

    public ShaderProgram getShaderProgram()

  Retrieves the current ShaderProgram object.

  Returns:
    the ShaderProgram object
  Throws:
    `CapabilityNotSetException` - if appropriate capability is not set and this object is part of live or compiled scene graph

### setShaderAttributeSet

    public void setShaderAttributeSet(ShaderAttributeSet shaderAttributeSet)

  Sets the ShaderAttributeSet object to the specified object. Setting it to null is equivalent to specifying an empty set of attributes.

  Parameters:
    `shaderAttributeSet` - object that specifies the desired shader attributes
  Throws:
    `CapabilityNotSetException` - if appropriate capability is not set and this object is part of live or compiled scene graph

### getShaderAttributeSet

    public ShaderAttributeSet getShaderAttributeSet()

  Retrieves the current ShaderAttributeSet object.

  Returns:
    the ShaderAttributeSet object
  Throws:
    `CapabilityNotSetException` - if appropriate capability is not set and this object is part of live or compiled scene graph

### cloneNodeComponent

    public NodeComponent cloneNodeComponent()

  Deprecated. replaced with cloneNodeComponent(boolean forceDuplicate)

  Overrides:
    `cloneNodeComponent` in class `Appearance`

### duplicateNodeComponent

    public void duplicateNodeComponent(NodeComponent originalNodeComponent)

  Deprecated. replaced with duplicateNodeComponent( NodeComponent originalNodeComponent, boolean forceDuplicate)

  NOTE: Applications should not call this method directly. It should only be called by the cloneNode method.

  Overrides:
    `duplicateNodeComponent` in class `Appearance`
