VolumetricLighting
Volumetric Lighting library for JMonkey Game Engine
Usage:
//1. FPP to add the filter
FilterPostProcessor filterPostProcessor = new FilterPostProcessor(assetManager);
//2. Basic settings
ColorRGBA color=new ColorRGBA(0.8f , 0.6f , 0f,1.0f ).mult(0.5f);
Vector3f pos= new Vector3f(1.4053185f, 5.5330953f, -1.5833765f);
//3. Spotlight which is contains basic config data and provides real lighting
SpotLight spot = new SpotLight();
spot.setSpotRange(6);
spot.setSpotInnerAngle(0.1f); //distance from pos - origin
spot.setSpotOuterAngle(0.4f); //width of the end part
spot.setColor(color);
spot.setPosition(pos);
spot.setDirection(new Vector3f(-0f,-1.0f,0.0f));
rootNode.addLight(spot);
//4. Filter config
VolumeLightFilter vsf = new VolumeLightFilter(spot, 128, 0.46f, rootNode);
vsf.setInensity(3);
//5. Add
filterPostProcessor.addFilter(vsf);
viewPort.addProcessor(filterPostProcessor);
