Class ComposeFilter

java.lang.Object

com.jme3.post.Filter

com.jme3.post.filters.ComposeFilter

All Implemented Interfaces:

Savable

public class ComposeFilter
extends Filter

This filter compose a texture with the viewport texture. This is used to compose post processed texture from another viewport. the compositing is done using the alpha value of the viewportTexture : mix(compositeTextureColor, viewPortColor, viewportColor.alpha); It's important for a good result that the viewport clear color alpha be 0.

Method Summary

Modifier and Type	Method and Description
Texture2D	getCompositeTexture()
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
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	setCompositeTexture(Texture2D compositeTexture) sets the compositeTexture
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);
