public void Invalidate(

Public Sub Invalidate ( 
	tile As TerrainTile,
	layer As TerrainLayer
)

public:
void Invalidate(
	TerrainTile^ tile, 
	TerrainLayer^ layer
)

member Invalidate : 
        tile : TerrainTile * 
        layer : TerrainLayer -> unit 

Parameters

tile

Type: DigitalRune.GraphicsTerrainTile
The terrain tile owning the terrain layer.

layer

Type: DigitalRune.GraphicsTerrainLayer
The terrain layer which should be invalidated.

This method notifies the renderers that cached data (e.g. terrain clipmaps) needs to be updated.

The Invalidate method or its overloads are called automatically when terrain tiles or layers are added to/removed from the terrain. If any other data that affects the appearance of the terrain is changed, the method Invalidate needs to be called manually.
