Detailed Description

Base class that users can derive from in order to implement custom passes for the compositor.

How to implement one: You need to derive three classes:

1. CompositorPassProvider
2. CompositorPassDef
3. CompositorPass

The first one is this class. You need to overload the two public virtuals. i.e. CompositorPassDef* MyProvider::addPassDef( ... ) { return OGRE_NEW MyPassDef( ... ); }

CompositorPass* MyProvider::addPass( ... ) { return OGRE_NEW MyPass( ... ); }

The second and third one are the implementations.

See also

CompositorPassScene and

CompositorPassSceneDef,

CompositorPassQuad and

CompositorPassQuadDef,

CompositorPassClear and

CompositorPassClearDef for examples on how to implement your own pass. For example, you could literally copy the code from CompositorPassClear & CompositorPassClearDef and implement your own custom pass that clears the render target.

Member Function Documentation

addPass()

virtual CompositorPass * Ogre::CompositorPassProvider::addPass ( const CompositorPassDef *  definition, Camera *  defaultCamera, CompositorNode *  parentNode, const CompositorChannel &  target, SceneManager *  sceneManager  )

pure virtual

Creates a CompositorPass from a CompositorPassDef for Compositor Pass of type 'custom'.

Remarks

If you have multiple custom pass types then you will need to use dynamic_cast<>() on the CompositorPassDef to determine what custom pass it is.

addPassDef()

virtual CompositorPassDef * Ogre::CompositorPassProvider::addPassDef ( CompositorPassType  passType, IdString  customId, CompositorTargetDef *  parentTargetDef, CompositorNodeDef *  parentNodeDef  )

pure virtual

Called from CompositorTargetDef::addPass when adding a Compositor Pass of type 'custom'.

Parameters

passType
customId	Arbitrary ID in case there is more than one type of custom pass you want to implement. Defaults to IdString()
rtIndex
parentNodeDef

inlineinherited

operator new() [1/3]

template<class Alloc >

void * Ogre::AllocatedObject< Alloc >::operator new ( size_t  sz )

inlineinherited

operator new() [2/3]

template<class Alloc >

void * Ogre::AllocatedObject< Alloc >::operator new ( size_t  sz, const char *  file, int  line, const char *  func  )

inlineinherited

operator new() [3/3]

operator new[]() [1/2]

template<class Alloc >

template<class Alloc >

void * Ogre::AllocatedObject< Alloc >::operator new[] ( size_t  sz, const char *  file, int  line, const char *  func  )

inlineinherited

translateCustomPass()

virtual void Ogre::CompositorPassProvider::translateCustomPass ( const AbstractNodePtr &  node, CompositorPassDef *  customPassDef  )

inlinevirtual

Optional override which allows users to define custom properties in the compositor scripts for custom passes.

Remarks

Please note this is called after CompositorPassProvider::addPassDef and similar to addPass you will need to dynamic_cast<>() to determine custom pass type.

Parameters

node	The AST node for this pass
customPassDef	The CompositorPassDef returned in CompositorPassProvider::addPassDef
