Member Data Documentation

constantHeight

float Ogre::Terrain::ImportData::constantHeight

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

deleteInputData

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.

inputBias

Real Ogre::Terrain::ImportData::inputBias

How to bias the input values provided (if any)

inputFloat

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.

inputImage

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.

inputScale

Real Ogre::Terrain::ImportData::inputScale

How to scale the input values provided (if any)

layerDeclaration

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.

layerList

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.

maxBatchSize

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).

minBatchSize

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.

pos

Vector3 Ogre::Terrain::ImportData::pos

Position of the terrain.

Remarks

Represents the position of the centre of the terrain.

terrainAlign

Alignment Ogre::Terrain::ImportData::terrainAlign

The alignment of the terrain.

terrainSize

uint16 Ogre::Terrain::ImportData::terrainSize

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

worldSize

Real Ogre::Terrain::ImportData::worldSize

The world size of the terrain.
