Helper method to render a composite map.

Parameters:

  size | The requested composite map size

  mat | The material to use to render the map
  outBox | The box region of the texture which has been updated, and should be copied into your final texture

virtual bool Ogre::TerrainMaterialGenerator::canGenerateUsingDeclaration | ( | const TerrainLayerDeclaration & | decl | ) | `[virtual, inherited]`

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.

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

virtual void Ogre::TerrainMaterialGenerator::setActiveProfile | ( | Profile * | p | ) | `[virtual, inherited]`

virtual void Ogre::TerrainMaterialGenerator::setDebugLevel | ( | unsigned int | dbg | ) | `[virtual, inherited]`

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.

Definition at line 349 of file OgreTerrainMaterialGenerator.h.

virtual void Ogre::TerrainMaterialGenerator::updateCompositeMap | ( | const Terrain * | terrain,
|  | const Rect & | rect
| ) |  | `[virtual, inherited]`

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.

virtual void Ogre::TerrainMaterialGenerator::updateParams | ( | const MaterialPtr & | mat,
