Terrain Namespace Reference

Classes
class	BufferCache
	Implements creation and caching of vertex buffers for terrain chunks. More...
class	ChunkManager
	Handles loading and caching of terrain chunks. More...
class	CompositeMap
class	CompositeMapRenderer
	The CompositeMapRenderer is responsible for updating composite map textures in a blocking or non-blocking way. More...
struct	LayerInfo
struct	TextureLayer
class	LodCallback
class	QuadTreeNode
class	DefaultLodCallback
class	RootNode
class	QuadTreeBuilder
class	QuadTreeWorld
	Terrain implementation that loads cells into a Quad Tree, with geometry LOD and texture LOD. The entire world is displayed at all times. More...
class	Storage
class	TerrainDrawable
class	MyView
class	TerrainGrid
	Simple terrain implementation that loads cells in a grid, with no LOD. Only requested cells are loaded. More...
struct	UpdateTextureFilteringFunctor
class	TextureManager
class	ViewData
class	ViewDataMap
class	View
	A View is a collection of rendering objects that are visible from a given camera/intersection. The base View class is part of the interface for usage in conjunction with preload feature. More...
class	World
	The basic interface for a terrain world. How the terrain chunks are paged and displayed is up to the implementation. More...
