Detailed Description

Page strategy which loads new pages based on a regular 3D grid.

Remarks

The grid can be up to 1024 x 1024 x 1024 cells in size. PageIDs are generated like this: (slice*1024 + row) * 1024 + col. The grid is centred around the grid origin, such that the boundaries of the cell around that origin are [-CellSize/2, CellSize/2)

Member Function Documentation

createData()

PageStrategyData* Ogre::Grid3DPageStrategy::createData ( )

virtual

Create a PageStrategyData instance containing the data specific to this PageStrategy.

This data will be held by a given PagedWorldSection and the structure of the data will be specific to the PageStrategy subclass.

Implements Ogre::PageStrategy.

destroyData()

void Ogre::Grid3DPageStrategy::destroyData ( PageStrategyData *  d )

virtual

Destroy a PageStrategyData instance containing the data specific to this PageStrategy.

This data will be held by a given PagedWorldSection and the structure of the data will be specific to the PageStrategy subclass.

Implements Ogre::PageStrategy.

frameEnd()

virtual void Ogre::PageStrategy::frameEnd ( Real  timeElapsed, PagedWorldSection *  section  )

inlinevirtualinherited

Called when the frame ends.

frameStart()

virtual void Ogre::PageStrategy::frameStart ( Real  timeSinceLastFrame, PagedWorldSection *  section  )

inlinevirtualinherited

Called when the frame starts.

getManager()

PageManager* Ogre::PageStrategy::getManager ( ) const

inlineinherited

getName()

const String& Ogre::PageStrategy::getName ( void  ) const

inlineinherited

getPageID()

PageID Ogre::Grid3DPageStrategy::getPageID ( const Vector3 &  worldPos, PagedWorldSection *  section  )

virtual

Get the page ID for a given world position.

Returns

The page ID

Implements Ogre::PageStrategy.

notifyCamera()

void Ogre::Grid3DPageStrategy::notifyCamera ( Camera *  cam, PagedWorldSection *  section  )

virtual

Called when a camera is used for any kind of rendering.

Remarks

This is probably the primary way in which the strategy will request new pages.

Parameters

cam	Camera which is being used for rendering. Class should not rely on this pointer remaining valid permanently because no notification will be given when the camera is destroyed.

Reimplemented from Ogre::PageStrategy.

updateDebugDisplay()

void Ogre::Grid3DPageStrategy::updateDebugDisplay ( Page *  p, SceneNode *  sn  )

virtual

Update the contents of the passed in SceneNode to reflect the debug display of a given page.

Remarks

The PageStrategy is to have complete control of the contents of this SceneNode, it must not be altered / added to by others.

Implements Ogre::PageStrategy.
