## Detailed Description

Options class which just stores default options for the terrain.

Remarks:
  None of these options are stored with the terrain when saved. They are options that you can use to modify the behaviour of the terrain when it is loaded or created.

Note:
  You should construct a single instance of this class per application and do so before you start working with any other terrain classes.

static TerrainGlobalOptions& Ogre::TerrainGlobalOptions::getSingleton | ( | void |  | ) | `[static]`

Override standard Singleton retrieval.

Remarks:
  Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

  This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

Reimplemented from Ogre::Singleton< TerrainGlobalOptions >.

void Ogre::TerrainGlobalOptions::setSkirtSize | ( | Real | skirtSz | ) |

method - the default size of 'skirts' used to hide terrain cracks (default 10)

Remarks:
  Changing this value only applies to Terrain instances loaded / reloaded afterwards.

Definition at line 1853 of file OgreTerrain.h.

void Ogre::TerrainGlobalOptions::setUseRayBoxDistanceCalculation | ( | bool | rb | ) |

Sets whether to use an accurate ray / box intersection to determine distance from a terrain tile, or whether to use the simple distance from the tile centre.

Using ray/box intersection will result in higher detail terrain because the LOD calculation is more conservative, assuming the 'worst case scenario' of a large height difference at the edge of a tile. This is guaranteed to give you at least the max pixel error or better, but will often give you more detail than you need. Not using the ray/box method is cheaper but will only use the max pixel error as a guide, the actual error will vary above and below that. The default is not to use the ray/box approach.

Definition at line 1942 of file OgreTerrain.h.

void Ogre::TerrainGlobalOptions::setVisibilityFlags | ( | uint32 | flags | ) |

Set the visbility flags that terrains will be rendered with.

Remarks:
  This applies to newly created terrains, after which they will maintain their own settings
