Detailed Description

Groups a number of TerrainRenderables (tiles) into a page, which is the unit of loading / unloading.

Remarks:: Note that this class, whilst holding onto TerrainRenderable instances, does not actually process or initialise them itself - this is intentional so the TerrainPageSource which is providing the tiles is able to load and prepare each renderable incrementally if required, thus avoiding any 'single hit' load methods for the page.

: All this class does do is pre-create a 2D vector of 'slots' in which to place the TerrainRenderable pointers, which it does on construction. Note that this structure is public to allow completely free access to users of this class.

Constructor & Destructor Documentation

Ogre::TerrainPage::TerrainPage ( unsigned short numTiles )

The main constructor.

Parameters:

numTiles The number of terrain tiles (TerrainRenderable) across (and down) a page

virtual Ogre::TerrainPage::~TerrainPage ( ) [virtual]

Destructor, will organise the deletion of pages.

Member Function Documentation

TerrainRenderable* Ogre::TerrainPage::getTerrainTile ( const Vector3 & pt )

Returns the TerrainRenderable that contains the given pt.
If no tile exists at the point, it returns 0;

void Ogre::TerrainPage::linkNeighbours ( void )

After TerrainRenderables have been populated, this method adds the neighbour links.

Remarks:
Should be called before adding the page to the scene manager.

void Ogre::TerrainPage::setRenderQueue ( RenderQueueGroupID qid )

Sets the render queue group which the tiles should be rendered in.

Member Data Documentation

SceneNode* Ogre::TerrainPage::pageSceneNode

Terrain2D Ogre::TerrainPage::tiles

2-dimensional vector of tiles, pre-allocated to the correct size

Definition at line 54 of file OgreTerrainPage.h.

unsigned short Ogre::TerrainPage::tilesPerPage

The number of tiles across a page.
