float Ogre::Terrain::ImportData::constantHeight

If neither inputImage or inputFloat are supplied, the constant height at which the initial terrain should be created (flat).

Definition at line 373 of file OgreTerrain.h.

Referenced by operator=().

bool Ogre::Terrain::ImportData::deleteInputData

Whether this structure should 'own' the input data (inputImage and inputFloat), and therefore delete it on destruction.

The default is false so you have to manage your own memory. If you set it to true, then you must have allocated the memory through OGRE_NEW (for Image) and OGRE_ALLOC_T (for inputFloat), the latter with the category MEMCATEGORY_GEOMETRY.

Real Ogre::Terrain::ImportData::inputBias

How to bias the input values provided (if any)

Definition at line 387 of file OgreTerrain.h.

Referenced by operator=().

float* Ogre::Terrain::ImportData::inputFloat

Optional list of terrainSize * terrainSize floats defining the terrain.

The list of floats wil be interpreted such that the first row in the array equates to the bottom row of vertices.

Definition at line 368 of file OgreTerrain.h.

Referenced by operator=().

Image* Ogre::Terrain::ImportData::inputImage

Optional heightmap providing the initial heights for the terrain.

Remarks: If supplied, should ideally be terrainSize * terrainSize, but if it isn't it will be resized.

Real Ogre::Terrain::ImportData::inputScale

How to scale the input values provided (if any)

Definition at line 385 of file OgreTerrain.h.

Referenced by operator=().

TerrainLayerDeclaration Ogre::Terrain::ImportData::layerDeclaration

Definition of the contents of each layer (required).

Most likely, you will pull a declaration from a TerrainMaterialGenerator of your choice.

Definition at line 393 of file OgreTerrain.h.

Referenced by operator=().

LayerInstanceList Ogre::Terrain::ImportData::layerList

List of layer structures, one for each layer required.

Can be empty or underfilled if required, list will be padded with blank textures.

Definition at line 398 of file OgreTerrain.h.

Referenced by operator=().

uint16 Ogre::Terrain::ImportData::maxBatchSize

Maximum batch size (along one edge) in vertices; must be 2^n+1 and <= 65.

Remarks: The terrain will be divided into hierarchical tiles, and this is the maximum size of one tile in vertices (at any LOD).

Definition at line 335 of file OgreTerrain.h.

Referenced by operator=().

uint16 Ogre::Terrain::ImportData::minBatchSize

Minimum batch size (along one edge) in vertices; must be 2^n+1.

Remarks: The terrain will be divided into tiles, and this is the minimum size of one tile in vertices (at any LOD). Adjacent tiles will be collected together into one batch to drop LOD levels once they are individually at this minimum, so setting this value higher means greater batching at the expense of making adjacent tiles use a common LOD. Once the entire terrain is collected together into one batch this effectively sets the minimum LOD.

Vector3 Ogre::Terrain::ImportData::pos

Position of the terrain.

Remarks: Represents the position of the centre of the terrain.

Definition at line 352 of file OgreTerrain.h.

Referenced by operator=().

Alignment Ogre::Terrain::ImportData::terrainAlign

The alignment of the terrain.

Definition at line 327 of file OgreTerrain.h.

Referenced by operator=().

uint16 Ogre::Terrain::ImportData::terrainSize

Terrain size (along one edge) in vertices; must be 2^n+1.

Definition at line 329 of file OgreTerrain.h.

Referenced by operator=().

Real Ogre::Terrain::ImportData::worldSize

The world size of the terrain.
