Description copied from class: Filter

Must return the material used for this filter. this method is called every frame.

Specified by:

getMaterial in class Filter

the material used for this filter.

initFilter

protected void initFilter(AssetManager manager,
 RenderManager renderManager,
 ViewPort vp,
 int w,
 int h)

Description copied from class: Filter

Initialization of filter subclasses. This method is called once when the filter is added to the FilterPostProcessor It should contain Material initializations and extra passes initialization

Specified by:

initFilter in class Filter

w - the width of the filter

h - the height of the filter

preFrame

protected void preFrame(float tpf)

Description copied from class: Filter

Override this method if you want to modify parameters according to tpf before the rendering of the frame. This is useful for animated filters Also it can be the place to render pre passes

Overrides:

preFrame in class Filter

Parameters:

tpf - the time used to render the previous frame

getDuration

public float getDuration()

returns the duration of the effect

Parameters:

ex - the exporter (not null)

Throws:

IOException - from the exporter

read

public void read(JmeImporter im)
          throws IOException
