VolumeTexture.AddDirtyBox Method ()
Adds a dirty region to a volume texture resource.
Overload List
public void AddDirtyBox(); public void AddDirtyBox(Box);
Remarks
For performance reasons, dirty regions are recorded only for level 0 of a texture. For sublevels, it is assumed that the corresponding (scaled) rectangle or box is also dirty. Dirty regions are automatically recorded when CubeTexture.LockRectangle is called without LockFlags.NoDirtyUpdate or LockFlags.ReadOnly.
Applications can specify which subset of a resource is copied in a Device.UpdateTexture call by specifying dirty regions. This can be used for optimization.
Exceptions
The method call is invalid. For example, a method's parameter might contain an invalid value.
