Detailed Description

The basic interface for a terrain world. How the terrain chunks are paged and displayed is up to the implementation.

Constructor & Destructor Documentation

		osg::Group *	compileRoot,
		Resource::ResourceSystem *	resourceSystem,
		Storage *	storage,
		int	nodeMask,

		int	borderMask
	)

Note: takes ownership of storage

Parameters

storage	Storage instance to get terrain data from (heights, normals, colors, textures..)
nodeMask	mask for the terrain root
preCompileMask	mask for pre compiling textures

Member Function Documentation

virtual void Terrain::World::cacheCell	(	View *	view,
		int	x,
		int	y
	)

inlinevirtual

Load a terrain cell at maximum LOD and store it in the View for later use.

Note: Thread safe.

Reimplemented in Terrain::QuadTreeWorld, and Terrain::TerrainGrid.

Here is the caller graph for this function:

void Terrain::World::clearAssociatedCaches ( )

virtual

Clears the cached land and landtexture data.

Note: Thread safe.

virtual View* Terrain::World::createView ( )

inlinevirtual

Create a View to use with preload feature. The caller is responsible for deleting the view.

Note: Thread safe.

Reimplemented in Terrain::QuadTreeWorld, and Terrain::TerrainGrid.

Here is the caller graph for this function:

virtual void Terrain::World::enable ( bool enabled )

inlinevirtual

Reimplemented in Terrain::QuadTreeWorld.

float Terrain::World::getHeightAt ( const osg::Vec3f & worldPos )

Here is the call graph for this function:

Here is the caller graph for this function:

Storage* Terrain::World::getStorage ( )

inline

void Terrain::World::loadCell	(	int	x,
		int	y
	)

virtual

Load the cell into the scene graph.

Note: Not thread safe.

Reimplemented in Terrain::TerrainGrid.

virtual void Terrain::World::preload	(	View *	view,
		const osg::Vec3f &	eyePoint
	)

inlinevirtual

Note: Thread safe, as long as you do not attempt to load into the same view from multiple threads.

Reimplemented in Terrain::QuadTreeWorld.

Here is the caller graph for this function:

virtual void Terrain::World::reportStats	(	unsigned int	frameNumber,
		osg::Stats *	stats
	)

inlinevirtual

Reimplemented in Terrain::QuadTreeWorld.

void Terrain::World::setBordersVisible ( bool visible )

virtual

virtual void Terrain::World::setDefaultViewer ( osg::Object * obj )

inlinevirtual

Set the default viewer (usually a Camera), used as viewpoint for any viewers that don't use their own viewpoint.

Reimplemented in Terrain::QuadTreeWorld.

void Terrain::World::setTargetFrameRate ( float rate )

See CompositeMapRenderer::setTargetFrameRate.

void Terrain::World::unloadCell	(	int	x,
		int	y
	)

virtual

Remove the cell from the scene graph.

Note: Not thread safe.

Reimplemented in Terrain::TerrainGrid.

Here is the caller graph for this function:

void Terrain::World::updateTextureFiltering ( )

Apply the scene manager's texture filtering settings to all cached textures.

Note: Thread safe.
