Detailed Description

Collection of renderables by priority.

This class simply groups renderables for rendering. All the renderables contained in this class are destined for the same RenderQueueGroup (coarse groupings like those between the main scene and overlays) and have the same priority (fine groupings for detailed overlap control).

This class can order solid renderables by a number of criteria; it can optimise them into groups based on pass to reduce render state changes, or can sort them by ascending or descending view depth. Transparent objects are always ordered by descending depth.

To iterate over items in the collections held by this object you should retrieve the collection in use (e.g. solids, solids with no shadows, transparents) and use the accept() method, providing a class implementing QueuedRenderableVisitor.

resetOrganisationModes()

void Ogre::RenderPriorityGroup::resetOrganisationModes

(

void

)

addOrganisationMode()

void Ogre::RenderPriorityGroup::addOrganisationMode

(

QueuedRenderableCollection::OrganisationMode

om

)

You can only do this when the group is empty, i.e. after clearing the queue.

See also

QueuedRenderableCollection::OrganisationMode

defaultOrganisationMode()

void Ogre::RenderPriorityGroup::defaultOrganisationMode

(

void

)

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

You can only do this when the group is empty, i.e. after clearing the queue.

sort()

void Ogre::RenderPriorityGroup::sort

(

const Camera *

cam

)

Sorts the objects which have been added to the queue; transparent objects by their depth in relation to the passed in Camera.

clear()

setSplitNoShadowPasses()

void Ogre::RenderPriorityGroup::setSplitNoShadowPasses ( bool  split )

inline

Sets whether or not passes which have shadow receive disabled should be separated.

setShadowCastersCannotBeReceivers()

merge()

void Ogre::RenderPriorityGroup::merge

(

const RenderPriorityGroup *

rhs

)

Merge group of renderables.
