Public function CreateTerrainMesh(Texture, HeightMap: TImage; const StretchSize: TDimension; MaxHeight: Single; Driver: TVideoDriver; const DefaultVertexBlockSize: TSize; DebugBorders: Boolean = False): TMesh; inline;

Creates a terrain mesh from an image representing a heightfield.

Parameters
Texture
The texture to apply to the terrain.
HeightMap
An image that will be interpreted as a heightmap. The brightness (average color) of each pixel is interpreted as a height, with a 255 brightness pixel producing the maximum height.
StretchSize

DefaultVertexBlockSize
(to be documented).
DebugBorders
(to be documented).
Returns
