Detailed Description

Class representing the invocation of queue groups in a RenderQueue.

Remarks:: The default behaviour for OGRE's render queue is to render each queue group in turn, dealing with shadows automatically, and rendering solids in grouped passes, followed by transparent objects in descending order. This class, together with RenderQueueInvocationSequence and the ability to associate one with a Viewport, allows you to change that behaviour and render queue groups in arbitrary sequence, repeatedly, and to skip shadows, change the ordering of solids, or even prevent OGRE controlling the render state during a particular invocation for special effects.

: Note that whilst you can change the ordering of rendering solids, you can't change the ordering on transparent objects, since to do this would cause them to render incorrectly.

: As well as using this class directly and using the options it provides you with, you can also provide subclasses of it to a RenderQueueInvocationSequence instance if you want to gain ultimate control.

Note:: Invocations will be skipped if there are scene-level options preventing them being rendered - for example special-case render queues and render queue listeners that dictate this.

virtual bool Ogre::RenderQueueInvocation::getSuppressRenderStateChanges ( void ) const [virtual]

Gets whether shadows are suppressed when invoking this queue.

virtual bool Ogre::RenderQueueInvocation::getSuppressShadows ( void ) const [virtual]

Gets whether shadows are suppressed when invoking this queue.

virtual void Ogre::RenderQueueInvocation::invoke ( RenderQueueGroup * group,

SceneManager * targetSceneManager

) [virtual]

Invoke this class on a concrete queue group.

Remarks:
Implementation will send the queue group to the target scene manager after doing what it needs to do.

virtual void Ogre::RenderQueueInvocation::setSolidsOrganisation ( QueuedRenderableCollection::OrganisationMode org ) [virtual]

Set the organisation mode being used for solids in this queue group invocation.

Definition at line 89 of file OgreRenderQueueInvocation.h.

virtual void Ogre::RenderQueueInvocation::setSuppressRenderStateChanges ( bool suppress ) [virtual]

Sets whether render state changes are suppressed when invoking this queue.

Remarks:
When doing special effects you may want to set up render state yourself and have it apply for the entire rendering of a queue. In that case, you should call this method with a parameter of 'true', and use a RenderQueueListener to set the render state directly on RenderSystem yourself before the invocation.

Suppressing render state changes is only intended for advanced use, don't use it if you're unsure of the effect. The only RenderSystem calls made are to set the world matrix for each object (note - view an projection matrices are NOT SET - they are under your control) and to render the object; it is up to the caller to do everything else, including enabling any vertex / fragment programs and updating their parameter state, and binding parameters to the RenderSystem. We advise you use a RenderQueueListener in order to get a notification when this invocation is going to happen (use an invocation name to identify it if you like), at which point you can set the state you need to apply before the objects are rendered.

Definition at line 131 of file OgreRenderQueueInvocation.h.

virtual void Ogre::RenderQueueInvocation::setSuppressShadows ( bool suppress ) [virtual]

Sets whether shadows are suppressed when invoking this queue.

Remarks:
When doing effects you often will want to suppress shadow processing if shadows will already have been done by a previous render.
