Constructor and Description
FogFilter() Creates a FogFilter
FogFilter(ColorRGBA fogColor, float fogDensity, float fogDistance) Create a fog filter

Method Summary

Modifier and Type	Method and Description
ColorRGBA	getFogColor() returns the fog color
float	getFogDensity() returns the fog density
float	getFogDistance() returns the fog distance
protected Material	getMaterial() Must return the material used for this filter.
protected void	initFilter(AssetManager manager, RenderManager renderManager, ViewPort vp, int w, int h) Initialization of sub classes filters This method is called once when the filter is added to the FilterPostProcessor It should contain Material initializations and extra passes initialization
protected boolean	isRequiresDepthTexture() Override this method and return true if your Filter needs the depth texture
void	read(JmeImporter im) Override this method if you want to load extra properties when the filter is loaded else only basic properties of the filter will be loaded This method should always begin by super.read(im);
void	setFogColor(ColorRGBA fogColor) Sets the color of the fog
void	setFogDensity(float fogDensity) Sets the density of the fog, a high value gives a thick fog
void	setFogDistance(float fogDistance) the distance of the fog.
void	write(JmeExporter ex) Override this method if you want to save extra properties when the filter is saved else only basic properties of the filter will be saved This method should always begin by super.write(ex);

Constructor Detail

FogFilter

public FogFilter()

Creates a FogFilter

FogFilter

public FogFilter(ColorRGBA fogColor,
                 float fogDensity,
                 float fogDistance)

Create a fog filter

Parameters:

fogColor - the color of the fog (default is white)

fogDensity - the density of the fog (default is 0.7)

fogDistance - the distance of the fog (default is 1000)

Method Detail

isRequiresDepthTexture

protected boolean isRequiresDepthTexture()

Description copied from class: Filter

Override this method and return true if your Filter needs the depth texture

Overrides:

isRequiresDepthTexture in class Filter

Returns:

true if your Filter need the depth texture

initFilter

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

Description copied from class: Filter

Initialization of sub classes filters 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

Parameters:

manager - the assetManager

renderManager - the renderManager

vp - the viewPort where this filter is rendered

w - the width of the filter

h - the height of the filter

getMaterial
