## 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 619 of file OgreRenderQueueSortingGrouping.h. References Ogre::RenderPriorityGroup::addOrganisationMode().

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

| Add a renderable to this group, with the given priority. Definition at line 492 of file OgreRenderQueueSortingGrouping.h. References Ogre::RenderPriorityGroup::addRenderable().

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 rougly the same kinds of renderables are going to be sent to the queue again next time. If true, completely destroys.
Definition at line 523 of file OgreRenderQueueSortingGrouping.h. References Ogre::RenderPriorityGroup::clear().

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. See also: QueuedRenderableCollection::OrganisationMode Definition at line 635 of file OgreRenderQueueSortingGrouping.h. References Ogre::RenderPriorityGroup::defaultOrganisationMode().

PriorityMapIterator Ogre::RenderQueueGroup::getIterator | ( | void |  | ) |

| Get an iterator for browsing through child contents. Definition at line 486 of file OgreRenderQueueSortingGrouping.h.

bool Ogre::RenderQueueGroup::getShadowsEnabled | ( | void |  | ) | const

| Are shadows enabled for this queue? Definition at line 555 of file OgreRenderQueueSortingGrouping.h.

void Ogre::RenderQueueGroup::resetOrganisationModes | ( | void |  | ) |

| Reset the organisation modes required 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 603 of file OgreRenderQueueSortingGrouping.h. References Ogre::RenderPriorityGroup::resetOrganisationModes().

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

| Sets whether or not objects which cast shadows should be treated as never receiving shadows. Definition at line 587 of file OgreRenderQueueSortingGrouping.h. References Ogre::RenderPriorityGroup::setShadowCastersCannotBeReceivers().

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 552 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 574 of file OgreRenderQueueSortingGrouping.h. References Ogre::RenderPriorityGroup::setSplitNoShadowPasses().

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

| Sets whether or not the queue will split passes by their lighting type, ie ambient, per-light and decal. Definition at line 560 of file OgreRenderQueueSortingGrouping.h. References Ogre::RenderPriorityGroup::setSplitPassesByLightingType().
