Alignment Ogre::Terrain::ImportData::terrainAlign |
The alignment of the terrain.
Referenced by operator=().
uint16 Ogre::Terrain::ImportData::terrainSize |
Terrain size (along one edge) in vertices; must be 2^n+1.
Referenced by operator=().
uint16 Ogre::Terrain::ImportData::maxBatchSize |
Maximum batch size (along one edge) in vertices; must be 2^n+1 and <= 65.
The terrain will be divided into hierarchical tiles, and this is the maximum size of one tile in vertices (at any LOD).
Referenced by operator=().
uint16 Ogre::Terrain::ImportData::minBatchSize |
Minimum batch size (along one edge) in vertices; must be 2^n+1.
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.
Represents the position of the centre of the terrain.
Referenced by operator=().
Real Ogre::Terrain::ImportData::worldSize |
The world size of the terrain.
Referenced by operator=().
Image* Ogre::Terrain::ImportData::inputImage |
Optional heightmap providing the initial heights for the terrain.
If supplied, should ideally be terrainSize * terrainSize, but if it isn't it will be resized.
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.
Referenced by operator=().
float Ogre::Terrain::ImportData::constantHeight |
If neither inputImage or inputFloat are supplied, the constant height at which the initial terrain should be created (flat).
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.
Referenced by operator=().
Real Ogre::Terrain::ImportData::inputScale |
How to scale the input values provided (if any)
Referenced by operator=().
Real Ogre::Terrain::ImportData::inputBias |
How to bias the input values provided (if any)
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.
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.
