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)

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.

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.

virtual void Ogre::PageStrategy::frameEnd	(	Real	timeElapsed,
		PagedWorldSection *	section
	)			`[virtual, inherited]`

Called when the frame ends.

Definition at line 93 of file OgrePageStrategy.h.

virtual void Ogre::PageStrategy::frameStart	(	Real	timeSinceLastFrame,
		PagedWorldSection *	section
	)			`[virtual, inherited]`

Called when the frame starts.

Definition at line 91 of file OgrePageStrategy.h.

PageManager* Ogre::PageStrategy::getManager ( ) const [inherited]

Definition at line 88 of file OgrePageStrategy.h.

const String& Ogre::PageStrategy::getName ( void ) const [inherited]

Definition at line 87 of file OgrePageStrategy.h.

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.

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.
