Protected Types

typedef vector< RenderablePass >
::type 
RenderablePassList
 Vector of RenderablePass objects, this is built on the assumption that vectors only ever increase in size, so even if we do clear() the memory stays allocated, ie fast.
typedef vector< Renderable * >
::type 
RenderableList
typedef map< Pass
*, RenderableList
*, PassGroupLess >::type 
PassGroupRenderableMap
 Map of pass to renderable lists, this is a grouping by pass.

Protected Member Functions

void acceptVisitorGrouped (QueuedRenderableVisitor *visitor) const
 Internal visitor implementation.
void acceptVisitorDescending (QueuedRenderableVisitor *visitor) const
 Internal visitor implementation.
void acceptVisitorAscending (QueuedRenderableVisitor *visitor) const
 Internal visitor implementation.

Protected Attributes

uint8 mOrganisationMode
 Bitmask of the organisation modes requested.
PassGroupRenderableMap mGrouped
 Grouped.
RenderablePassList mSortedDescending
 Sorted descending (can iterate backwards to get ascending).

Static Protected Attributes

static RadixSort
< RenderablePassList,
RenderablePass, uint32
msRadixSorter1
 Radix sorter for accessing sort value 1 (Pass).
static RadixSort
< RenderablePassList,
RenderablePass, float > 
msRadixSorter2
 Radix sorter for sort value 2 (distance).

Detailed Description

Lowest level collection of renderables.

Remarks:
To iterate over items in this collection, you must call the accept method and supply a QueuedRenderableVisitor. The order of the iteration, and whether that iteration is over a RenderablePass list or a 2-level grouped list which causes a visit call at the Pass level, and a call for each Renderable underneath.

Definition at line 113 of file OgreRenderQueueSortingGrouping.h.


Member Typedef Documentation

Map of pass to renderable lists, this is a grouping by pass.

Definition at line 199 of file OgreRenderQueueSortingGrouping.h.

Definition at line 197 of file OgreRenderQueueSortingGrouping.h.

Vector of RenderablePass objects, this is built on the assumption that vectors only ever increase in size, so even if we do clear() the memory stays allocated, ie fast.

Definition at line 196 of file OgreRenderQueueSortingGrouping.h.


Member Enumeration Documentation

Organisation modes required for this collection.

Remarks:
This affects the internal placement of the items added to this collection; if only one type of sorting / grouping is to be required, then renderables can be stored only once, whilst if multiple types are going to be needed then internally there will be multiple organisations. Changing the organisation needs to be done when the collection is empty.
Enumerator:
OM_PASS_GROUP 

Group by pass.

OM_SORT_DESCENDING 

Sort descending camera distance.

OM_SORT_ASCENDING 

Sort ascending camera distance Note value overlaps with descending since both use same sort.

Definition at line 124 of file OgreRenderQueueSortingGrouping.h.

void Ogre::QueuedRenderableCollection::acceptVisitor ( QueuedRenderableVisitor visitor,
OrganisationMode  om 
) const

Accept a visitor over the collection contents.

Parameters:
visitor Visitor class which should be called back
om The organisation mode which you want to iterate over. Note that this must have been included in an addOrganisationMode call before any renderables were added.
void Ogre::QueuedRenderableCollection::acceptVisitorAscending ( QueuedRenderableVisitor visitor  )  const [protected]

Internal visitor implementation.

void Ogre::QueuedRenderableCollection::acceptVisitorDescending ( QueuedRenderableVisitor visitor  )  const [protected]

Internal visitor implementation.

void Ogre::QueuedRenderableCollection::acceptVisitorGrouped ( QueuedRenderableVisitor visitor  )  const [protected]

Internal visitor implementation.

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

Add a required sorting / grouping mode to this collection when next used.

Remarks:
You can only do this when the collection is empty.
