Detailed Description

A terrain filter takes a height field as input and output another height field.

There are two interfaces to access a terrain filter: The shell interface (I3DShTerrainFilter) and the external interface (I3DExTerrainFilter) . You can get one from the other using QueryInterface.

Whenever it is possible you should use the Shell interface (I3DShTerrainFilter) to access the component because the Shell will make sure that the parameter map of the external component is valid. This is especially important if the component is animated. For more information on components see the Overview of the SDK.

Member Function Documentation

virtual boolean MCCOMAPI I3DShTerrainFilter::CanBuildPreview (  )  [pure virtual]

Returns true if the filter is able to make a preview of the final map working on a smaller map

virtual void MCCOMAPI I3DShTerrainFilter::Filter ( TMCArray< real > &  heightField,
TVector2 heightBound,
const TIndex2 size,
const TVector2 cellSize 
) [pure virtual]

Filter the height field. This is where the real work is done.

Parameters:
heightField Array of real that defines the height field.
heightBound Height min and max of the terrain (must be updated by this function if the height bounds changed)
size size of the array
cellSize size of a cell of the grid
virtual I3DShPrimitiveComponent* MCCOMAPI I3DShTerrainFilter::GetTerrain (  )  [pure virtual]

Returns the terrain primitive on which the filter is applied

virtual void MCCOMAPI I3DShTerrainFilter::SetTerrain ( I3DShPrimitiveComponent terrainPrimitive  )  [pure virtual]

Sets the terrain on which the filter is applied

Parameters:
terrainPrimitive A pointer to the terrain primitive.
virtual void MCCOMAPI I3DShTerrainFilter::Shuffle (  )  [pure virtual]

Should change the seed of the random generator used by this filter (if the filter has a random component).
