	Aabb aabb
)

member Invalidate : 
        aabb : Aabb -> unit 

Parameters

aabb

Type: DigitalRune.Geometry.ShapesAabb
The axis-aligned bounding box of the invalid region.

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.
