◆ _getCompositeMapRTT()

Texture * Ogre::TerrainMaterialGenerator::_getCompositeMapRTT ( )
inlineinherited

◆ _markChanged()

void Ogre::TerrainMaterialGenerator::_markChanged ( )
inlineinherited

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

◆ _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
sizeThe requested composite map size
rectThe region of the composite map to update, in image space
matThe material to use to render the map
destCompositeMapA TexturePtr for the composite map to be written into

◆ 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.

◆ generate()

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

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

◆ 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.

◆ getActiveProfile()

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

Get the active profile.

◆ 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.

◆ getDebugLevel()

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

Get the debug level of the material.

◆ getLayerDeclaration()

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

Get the layer declaration that this material generator operates with.

◆ 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.

◆ getProfiles()

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

Get the list of profiles that this generator supports.

◆ 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.

◆ operator new() [2/3]

inlineinherited

operator new, with debug line info

template<class Alloc >
void * Ogre::AllocatedObject< Alloc >::operator new[] ( size_t  sz,
const char file,

)
inlineinherited

array operator new, with debug line info

◆ requestOptions()

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

Triggers the generator to request the options that it needs.

◆ 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.

◆ 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.

◆ 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).

◆ 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.

◆ updateParams()

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

Update parameters for the given terrain using the active profile.

◆ 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.
