◆ renderableQueued()

virtual bool Ogre::RenderQueue::RenderableListener::renderableQueued ( Renderable rend,
uint8  groupID,
ushort  priority,
Technique **  ppTech,
RenderQueue pQueue 
)
pure virtual

Method called when a Renderable is added to the queue.

Remarks
You can use this event hook to alter the Technique used to render a Renderable as the item is added to the queue. This is a low-level way to override the material settings for a given Renderable on the fly.
Parameters
rendThe Renderable being added to the queue
groupIDThe render queue group this Renderable is being added to
priorityThe priority the Renderable has been given
ppTechA pointer to the pointer to the Technique that is intended to be used; you can alter this to an alternate Technique if you so wish (the Technique doesn't have to be from the same Material either).
pQueuePointer to the render queue that this object is being added to. You can for example call this back to duplicate the object with a different technique
Returns
true to allow the Renderable to be added to the queue, false if you want to prevent it being added
