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
