C# Класс Axiom.Components.Terrain.TerrainMaterialGenerator

Class that provides functionality to generate materials for use with a terrain.

Terrains are composed of one or more layers of texture information, and require that a material is generated to render them. There are various approaches to rendering the terrain, which may vary due to:

Hardware support (static)
Texture instances assigned to a particular terrain (dynamic in an editor)
User selection (e.g. changing to a cheaper option in order to increase performance, or in order to test how the material might look on other hardware (dynamic)

Subclasses of this class are responsible for responding to these factors and to generate a terrain material. @par In order to cope with both hardware support and user selection, the generator must expose a number of named 'profiles'. These profiles should function on a known range of hardware, and be graded by quality. At runtime, the user should be able to select the profile they wish to use (provided hardware support is available).

Метод	Описание
CanGenerateUsingDeclaration ( TerrainLayerDeclaration decl ) : bool	Whether this generator can generate a material for a given declaration. By default this only returns true if the declaration is equal to the standard one returned from getLayerDeclaration, but if a subclass wants to be flexible to generate materials for other declarations too, it can specify here.
Dispose ( ) : void
Generate ( Axiom.Components.Terrain.Terrain terrain ) : Material	Generate a material for the given terrain using the active profile.
GenerateForCompositeMap ( Axiom.Components.Terrain.Terrain terrain ) : Material	Generate a material for the given composite map of the terrain using the active profile.
GetMaxLayers ( Axiom.Components.Terrain.Terrain terrain ) : byte	Get the maximum number of layers supported with the given terrain.
MarkChanged ( ) : void	Internal method - indicates that a change has been made that would require material regeneration
RenderCompositeMap ( int size, Rectangle rect, Material mat, Axiom.Core.Texture destCompositeMap ) : void	Helper method to render a composite map.
RequestOption ( Axiom.Components.Terrain.Terrain terrain ) : void	Triggers the generator to request the options that it needs.
SetActiveProfile ( string name ) : void	Set the active profile by name.
UpdateCompositeMap ( Axiom.Components.Terrain.Terrain terrain, Rectangle rect ) : void	Update the composite map for a terrain. The composite map for a terrain must match what the terrain should look like at distance. This method will only be called in the render thread so the generator is free to render into a texture to support this, so long as the results are blitted into the Terrain's own composite map afterwards.
UpdateParams ( Material mat, Axiom.Components.Terrain.Terrain terrain ) : void	Update parameters for the given terrain using the active profile.
UpdateParamsForCompositeMap ( Material mat, Axiom.Components.Terrain.Terrain terrain ) : void	Update parameters for the given terrain using the active profile.

UpdateCompositeMap() публичный метод

Update the composite map for a terrain. The composite map for a terrain must match what the terrain should look like at distance. This method will only be called in the render thread so the generator is free to render into a texture to support this, so long as the results are blitted into the Terrain's own composite map afterwards.
