Member Function Documentation

◆ getProfiles()

virtual const ProfileList& Ogre::TerrainMaterialGenerator::getProfiles ( ) const

inlinevirtualinherited

Get the list of profiles that this generator supports.

◆ setActiveProfile() [1/2]

virtual void Ogre::TerrainMaterialGenerator::setActiveProfile ( const String & name )

inlinevirtualinherited

Set the active profile by name.

◆ setActiveProfile() [2/2]

virtual void Ogre::TerrainMaterialGenerator::setActiveProfile ( Profile * p )

inlinevirtualinherited

Set the active Profile.

◆ getActiveProfile()

Profile* Ogre::TerrainMaterialGenerator::getActiveProfile ( ) const

inlineinherited

Get the active profile.

◆ _markChanged()

void Ogre::TerrainMaterialGenerator::_markChanged ( )

inlineinherited

Internal method - indicates that a change has been made that would require material regeneration.

◆ getChangeCount()

unsigned long long int Ogre::TerrainMaterialGenerator::getChangeCount ( ) const

inlineinherited

Returns the number of times the generator has undergone a change which would require materials to be regenerated.

◆ getLayerDeclaration()

virtual const TerrainLayerDeclaration& Ogre::TerrainMaterialGenerator::getLayerDeclaration ( ) const

inlinevirtualinherited

Get the layer declaration that this material generator operates with.

◆ canGenerateUsingDeclaration()

virtual bool Ogre::TerrainMaterialGenerator::canGenerateUsingDeclaration ( const TerrainLayerDeclaration & decl )

inlinevirtualinherited

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.

◆ isVertexCompressionSupported()

virtual bool Ogre::TerrainMaterialGenerator::isVertexCompressionSupported ( ) const

inlinevirtualinherited

Return whether this material generator supports using a compressed vertex format.

This is only possible when using shaders.

◆ requestOptions()

virtual void Ogre::TerrainMaterialGenerator::requestOptions ( Terrain * terrain )

inlinevirtualinherited

Triggers the generator to request the options that it needs.

References Ogre::TerrainMaterialGenerator::Profile::requestOptions().

◆ generate()

virtual MaterialPtr Ogre::TerrainMaterialGenerator::generate ( const Terrain * terrain )

inlinevirtualinherited

Generate a material for the given terrain using the active profile.

References Ogre::TerrainMaterialGenerator::Profile::generate().

◆ generateForCompositeMap()

virtual MaterialPtr Ogre::TerrainMaterialGenerator::generateForCompositeMap ( const Terrain * terrain )

inlinevirtualinherited

Generate a material for the given composite map of the terrain using the active profile.

References Ogre::TerrainMaterialGenerator::Profile::generateForCompositeMap().

◆ setLightmapEnabled()

virtual void Ogre::TerrainMaterialGenerator::setLightmapEnabled ( bool enabled )

inlinevirtualinherited

Whether to support a light map over the terrain in the shader, if it's present (default true).

References Ogre::TerrainMaterialGenerator::Profile::setLightmapEnabled().

◆ getMaxLayers()

virtual uint8 Ogre::TerrainMaterialGenerator::getMaxLayers ( const Terrain * terrain ) const

inlinevirtualinherited

Get the maximum number of layers supported with the given terrain.

Note: When you change the options on the terrain, this value can change.

References Ogre::TerrainMaterialGenerator::Profile::getMaxLayers().

◆ updateCompositeMap()

virtual void Ogre::TerrainMaterialGenerator::updateCompositeMap	(	const Terrain *	terrain,
		const Rect &	rect
	)

inlinevirtualinherited

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.

References Ogre::TerrainMaterialGenerator::Profile::updateCompositeMap().

◆ updateParams()

virtual void Ogre::TerrainMaterialGenerator::updateParams	(	const MaterialPtr &	mat,
		const Terrain *	terrain
	)

inlinevirtualinherited

Update parameters for the given terrain using the active profile.

References Ogre::TerrainMaterialGenerator::Profile::updateParams().

◆ updateParamsForCompositeMap()

virtual void Ogre::TerrainMaterialGenerator::updateParamsForCompositeMap	(	const MaterialPtr &	mat,
		const Terrain *	terrain
	)

inlinevirtualinherited

Update parameters for the given terrain composite map using the active profile.

References Ogre::TerrainMaterialGenerator::Profile::updateParamsForCompositeMap().

◆ setDebugLevel()

virtual void Ogre::TerrainMaterialGenerator::setDebugLevel ( unsigned int dbg )

inlinevirtualinherited

Set the debug level of the material.

Remarks: Sets the level of debug display for this material. What this debug level means is entirely depdendent on the generator, the only constant is that 0 means 'no debug' and non-zero means 'some level of debugging', with any graduations in non-zero values being generator-specific.

◆ getDebugLevel()

virtual unsigned int Ogre::TerrainMaterialGenerator::getDebugLevel ( ) const

inlinevirtualinherited

Get the debug level of the material.

◆ _renderCompositeMap()

virtual void Ogre::TerrainMaterialGenerator::_renderCompositeMap	(	size_t	size,
		const Rect &	rect,
		const MaterialPtr &	mat,
		const TexturePtr &	destCompositeMap
	)

virtualinherited

Helper method to render a composite map.

Parameters

size	The requested composite map size
rect	The region of the composite map to update, in image space
mat	The material to use to render the map
destCompositeMap	A TexturePtr for the composite map to be written into

◆ _getCompositeMapRTT()

Texture* Ogre::TerrainMaterialGenerator::_getCompositeMapRTT ( )
