Class Compositor

java.lang.Object

com.bonzaiengine.renderer.deferred.Compositor

All Implemented Interfaces:

IDestroyable

public class Compositor
extends java.lang.Object
implements IDestroyable

Full screen compositor

Implementation example:
Fragment code:

 uniform sampler2D diffuseSpecMap;
 uniform sampler2D lightFactorsMap;
 varying vec2 vUv;
 void main() {
        vec4 diffuseSpec = texture2D(lightFactorsMap, vUv);
        vec4 lightFactors = texture2D(lightFactorsMap, vUv);
        vec4 finalColor = diffuseSpec * lightFactors;
        gl_FragColor = vec4(finalColor.rgb + finalColor.a, 1.0);
 }

Implementation:

 new Compositor(gl, fragmentStream) {
