Class BloomFilter

java.lang.Object

com.jme3.post.Filter

com.jme3.post.filters.BloomFilter

All Implemented Interfaces:

Savable

public class BloomFilter
extends Filter

BloomFilter is used to make objects in the scene have a glow effect.
There are 2 mode : Scene and Objects.
Scene mode extracts the bright parts of the scene to make them glow
Object mode makes objects glow according to their material's glowMap or their GlowColor
See advanced:bloom_and_glow for more details

Constructor Detail

BloomFilter

public BloomFilter()

Creates a Bloom filter

BloomFilter

public BloomFilter(BloomFilter.GlowMode glowMode)

Creates the bloom filter with the specified glow mode

Parameters:

glowMode - the desired mode (default=Scene)

Method Detail

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

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

reInitFilter

protected void reInitFilter()

getMaterial

protected Material getMaterial()

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

Returns:

the material used for this filter.

postQueue

protected void postQueue(RenderQueue queue)

Description copied from class: Filter

Override this method if you want to make a pre pass, before the actual rendering of the frame

Overrides:

postQueue in class Filter

Parameters:

queue - the RenderQueue

cleanUpFilter

protected void cleanUpFilter(Renderer r)

Description copied from class: Filter

override this method if you have some cleanup to do

Overrides:

cleanUpFilter in class Filter

Parameters:

r - the renderer

getBloomIntensity

public float getBloomIntensity()

returns the bloom intensity

Returns:

the intensity value

setBloomIntensity

public void setBloomIntensity(float bloomIntensity)

intensity of the bloom effect default is 2.0

Parameters:

bloomIntensity - the desired intensity (default=2)

getBlurScale

public float getBlurScale()

returns the blur scale

Returns:

the blur scale

setBlurScale

public void setBlurScale(float blurScale)

sets The spread of the bloom default is 1.5f

Parameters:

blurScale - the desired scale (default=1.5)

getExposureCutOff

public float getExposureCutOff()

returns the exposure cutoff
for more details see setExposureCutOff(float exposureCutOff)

Returns:

the exposure cutoff

setExposureCutOff

public void setExposureCutOff(float exposureCutOff)

Define the color threshold on which the bloom will be applied (0.0 to 1.0)

Parameters:

exposureCutOff - the desired threshold (≥0, ≤1, default=0)

getExposurePower

public float getExposurePower()

returns the exposure power
for more details see setExposurePower(float exposurePower)

Returns:

the exposure power

setExposurePower

public void setExposurePower(float exposurePower)

defines how many times the bloom extracted color will be multiplied by itself. default is 5.0
a high value will reduce rough edges in the bloom and somehow the range of the bloom area

Parameters:

exposurePower - the desired exponent (default=5)

getDownSamplingFactor

public float getDownSamplingFactor()

returns the downSampling factor
for more details see setDownSamplingFactor(float downSamplingFactor)

Returns:

the downsampling factor

setDownSamplingFactor

public void setDownSamplingFactor(float downSamplingFactor)

Sets the downSampling factor : the size of the computed texture will be divided by this factor. default is 1 for no downsampling A 2 value is a good way of widening the blur

Parameters:

downSamplingFactor - the desired factor (default=1)
