Detailed Description

"Empty" shader that does nothing, used to allow the shader interface to be used by datafactories. It will never be able to be rendered, as is impossible to have an implementation for it.

Member Function Documentation

appliesSpecular()

bool appliesSpecular ( )

inlineoverridevirtual

Sub-classes only need to overide this if they apply specular high-lights (eg. Blinn-Phong).

Reimplemented from Shader.

appliesTransparency()

bool appliesTransparency ( ) const

inlineoverridevirtual

Subclasses must override this to specify whether they apply transparency to objects or not when they are enabled.

Implements Shader.

clone()

NullShader * clone ( ) const

inlineoverridevirtual

Returns

A clone of this object.

Note

Subclasses would normally return their own type rather than the Clonable type. The C++ language rules allow a more derived type to be returned from a virtual function and the compiler will still treat it as a valid override.

Implements Shader.

createImplementation()

ShaderImplementation * createImplementation ( SceneRenderer &  )

inlineoverridevirtual

Implements Shader.
