## Detailed Description

A grouping level underneath RenderQueue which groups renderables to be issued at coarsely the same time to the renderer.

Remarks:
  Each instance of this class itself hold RenderPriorityGroup instances, which are the groupings of renderables by priority for fine control of ordering (not required for most instances).

## Member Function Documentation

void Ogre::RenderQueueGroup::addOrganisationMode | ( | QueuedRenderableCollection::OrganisationMode | om | ) |

Add a required sorting / grouping mode for the solids in this group.

Remarks:
  You can only do this when the group is empty, ie after clearing the queue.

See also:
  QueuedRenderableCollection::OrganisationMode

Definition at line 655 of file OgreRenderQueueSortingGrouping.h.

void Ogre::RenderQueueGroup::addRenderable | ( | Renderable * | pRend,
|  | Technique * | pTech,
|  | ushort | priority
| ) |  |

Add a renderable to this group, with the given priority.

Definition at line 520 of file OgreRenderQueueSortingGrouping.h.

References Ogre::RenderPriorityGroup::addOrganisationMode(), Ogre::RenderPriorityGroup::addRenderable(), OGRE_NEW, and Ogre::RenderPriorityGroup::resetOrganisationModes().

void Ogre::RenderQueueGroup::clear | ( | bool | destroy = `false` | ) |

Clears this group of renderables.

Parameters:

  destroy | If false, doesn't delete any priority groups, just empties them. Saves on memory deallocations since the chances are roughly the same kinds of renderables are going to be sent to the queue again next time. If true, completely destroys.

void Ogre::RenderQueueGroup::defaultOrganisationMode | ( | void |  | ) |

Setthe sorting / grouping mode for the solids in this group to the default.

Remarks:
  You can only do this when the group is empty, ie after clearing the queue.

Definition at line 637 of file OgreRenderQueueSortingGrouping.h.

void Ogre::RenderQueueGroup::setShadowCastersCannotBeReceivers | ( | bool | ind | ) |

Sets whether or not objects which cast shadows should be treated as never receiving shadows.

Definition at line 621 of file OgreRenderQueueSortingGrouping.h.

void Ogre::RenderQueueGroup::setShadowsEnabled | ( | bool | enabled | ) |

Indicate whether a given queue group will be doing any shadow setup.

Remarks:
  This method allows you to inform the queue about a queue group, and to indicate whether this group will require shadow processing of any sort. In order to preserve rendering order, OGRE has to treat queue groups as very separate elements of the scene, and this can result in it having to duplicate shadow setup for each group. Therefore, if you know that a group which you are using will never need shadows, you should preregister the group using this method in order to improve the performance.

Definition at line 586 of file OgreRenderQueueSortingGrouping.h.

void Ogre::RenderQueueGroup::setSplitNoShadowPasses | ( | bool | split | ) |

Sets whether or not the queue will split passes which have shadow receive turned off (in their parent material), which is needed when certain shadow techniques are used.

Definition at line 608 of file OgreRenderQueueSortingGrouping.h.

void Ogre::RenderQueueGroup::setSplitPassesByLightingType | ( | bool | split | ) |
