class RenderModifier

Class RenderModifier: Some ModelRenderer implementations provide vertex management behaviour but allow fragment stages to be modified by a plugged in RenderModifier. You should use RenderModifierPtr when referencing RenderModifiers.

RenderModifier

public RenderModifier();

~RenderModifier

public virtual ~RenderModifier();

BeginPass

public virtual u32 BeginPass( uint pass )= 0;

BeginPass: Setup OpenGL for the given rendering pass. Must be implemented by derived classes.

Parameters:

pass - The current pass number (pass == 0 is the first pass)

Returns:

The streamflags that indicate which vertex components are required by the fragment stages (see STREAM_XYZ constants).

EndPass

public virtual bool EndPass( uint pass )= 0;

EndPass: Cleanup OpenGL state after the given pass. This function may indicate that additional passes are needed. Must be implemented by derived classes.

Parameters:

pass - The current pass number (pass == 0 is the first pass)

Returns:

true if rendering is complete, false if an additional pass is needed. If false is returned, BeginPass is then called with an increased pass number.

GetTexGenMatrix

public const CMatrix3D* GetTexGenMatrix( uint UNUSED( pass ) );

GetTexGenMatrix: If BeginPass returns STREAM_TEXGENTOUVx, the caller must call this function to query the texture matrix that will be used to transform vertex positions into texture coordinates. Default implementation raises a runtime error.

Parameters:

pass - the current pass number (pass == 0 is the first pass)

Returns:

a pointer to the texture matrix for the given pass

PrepareModel

public void PrepareModel( uint UNUSED( pass ), CModel* UNUSED( model ) );

LitRenderModifier implementation

PrepareTexture

public virtual void PrepareTexture( uint pass, CTexture* texture )= 0;

PrepareTexture: Called before rendering models that use the given texture. Must be implemented by derived classes.

Parameters:

pass - The current pass number (pass == 0 is the first pass)

texture - The texture used by subsequent models
