Method Detail

getAmount
public float getAmount() Gets the amount of ghosting, which corresponds to the scaling of the ghost image. Returns: Ghosting amount

render
public void render( int pass, RenderingContext context, RenderTarget renderedFrame ) Renders the frame for the current pass. On pass 0 the raw rendering output is given to the function, and subsequent passes receive output from their predecessor. The rendering context can be used to draw elements for the next pass (if there is one), or for the final output of this filter. Note that the result of the final pass might still be processed by other post-processing filters before actually being displayed on the screen. Specified By: render in PostProcessingFilter

public void render(
    int pass,

    RenderTarget renderedFrame
)
