com.jme3.post.ssao.SSAOFilter
public class SSAOFilter
SSAO stands for screen space ambient occlusion It's a technique that fake ambient lighting by computing shadows that near by objects would casts on each others under the effect of an ambient light more info on this in this blog post http://jmonkeyengine.org/2010/08/16/screen-space-ambient-occlusion-for-jmonkeyengine-3-0/

SSAOFilter()
Create a Screen Space Ambient Occlusion Filter |
|
SSAOFilter(float sampleRadius,
float intensity,
float scale,
float bias)
Create a Screen Space Ambient Occlusion Filter |
Method Summary | |
---|---|
float |
getBias()
Return the bias see setBias(float bias) |
float |
getIntensity()
returns the ambient occlusion intensity |
protected Material |
getMaterial()
Must return the material used for this filter. |
float |
getSampleRadius()
returns the sample radius see {link setSampleRadius(float sampleRadius)} |
float |
getScale()
returns the scale see setScale(float scale) |
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 |
boolean |
isUseAo()
debugging only , will be removed |
boolean |
isUseOnlyAo()
debugging only , will be removed |
protected void |
postQueue(RenderManager renderManager,
ViewPort viewPort)
Override this method if you want to make a pre pass, before the actual rendering of the frame |
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 |
setBias(float bias)
Sets the the width of the occlusion cone considered by the occludee default is 0.1f |
void |
setIntensity(float intensity)
Sets the Ambient occlusion intensity default is 1.2f |
void |
setSampleRadius(float sampleRadius)
Sets the radius of the area where random samples will be picked dafault 5.1f |
void |
setScale(float scale)
Returns the distance between occluders and occludee. |
void |
setUseAo(boolean useAo)
debugging only , will be removed |
void |
setUseOnlyAo(boolean useOnlyAo)
debugging only , will be removed |
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); |
