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.

◆ getSingleton()

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.

◆ getSingletonPtr()

void Ogre::TerrainGlobalOptions::setCastsDynamicShadows ( bool s )

inline

Whether the terrain will be able to cast shadows (texture shadows only are supported, and you must be using depth shadow maps).

This value can be set dynamically, and affects all existing terrains. It defaults to false.

◆ setCompositeMapAmbient()

inline

Set the composite map ambient light to use.

◆ setCompositeMapDiffuse()

inline

Set the default world size for a layer 'splat' texture to cover.

◆ setDefaultMaterialGenerator()

Set the default material generator.

◆ setDefaultResourceGroup()

inline

Set the default resource group to use to load / save terrains.

◆ setLayerBlendMapSize()

void Ogre::TerrainGlobalOptions::setLayerBlendMapSize ( uint16 sz )

inline

Sets the default size of blend maps for a new terrain.

This is the resolution of each blending layer for a new terrain. Once created, this information will be stored with the terrain.

◆ setLightMapDirection()

void Ogre::TerrainGlobalOptions::setLightMapDirection ( const Vector3 & v )

inline

Set the shadow map light direction to use (world space).

◆ setLightMapSize()

void Ogre::TerrainGlobalOptions::setLightMapSize ( uint16 sz )

inline

Sets the default size of lightmaps for a new terrain.

◆ setMaxPixelError()

void Ogre::TerrainGlobalOptions::setMaxPixelError ( Real pixerr )

inline

Set the maximum screen pixel error that should be allowed when rendering.

Note: This value can be varied dynamically and affects all existing terrains. It will be weighted by the LOD bias on viewports.

◆ setQueryFlags()

void Ogre::TerrainGlobalOptions::setQueryFlags ( uint32 flags )

inline

Set the default query flags for terrains.

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

◆ setRenderQueueGroup()

void Ogre::TerrainGlobalOptions::setRenderQueueGroup ( uint8 grp )

inline

Set the render queue group that terrains will be rendered into.

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

◆ setSkirtSize()

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

inline

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.

◆ setUseRayBoxDistanceCalculation()

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

inline

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.

◆ setUseVertexCompressionWhenAvailable()

void Ogre::TerrainGlobalOptions::setUseVertexCompressionWhenAvailable ( bool enable )

inline

Set whether to allow vertex compression to be used when the material generator states that it supports it.

Note: You should only call this before creating any terrain instances. The default is true, so if a material generator supports compressed vertices, and so does the hardware (this basically means shader support), they will be used). However you can disable this in an emergency if required.

◆ setVisibilityFlags()

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

inline

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
