Shadow Shader

[AGP]

I'd love for you to include this shader in jpct. This is an example of how to call it:

Code Select Expand

//In the game loop:
           shadows.setCenter(batman.model.get(0).getTransformedCenter());
           shadows.updateShadowMap(theWorld, buffer, camera);
//The setup:
    private void setupShadows() {
       shadows = new ShadowMapper(1024);
       shadows.setLightDirection(new SimpleVector(.2f, .4f, -.3f));

       shadows.setShadowArea(360f);//120f
       shadows.setShadowBias(0.00f);
       shadows.setShadowDarkness(0.50f);
       shadows.setCenter(batman.model.get(0).getTransformedCenter());

       // ALL visible objects must be casters
       for (Object3D part : batman.model)
           shadows.addCaster(part);
       shadows.addCaster(batman.cape);

       for (Object3D part : joker.model)
           shadows.addCaster(part);

       shadows.addCaster(catwoman);

       shadows.addCaster(batmobile.hull);
       shadows.addCaster(grappleTarget);

       shadows.addReceiver(ground);

       for (Object3D obj : cityObjects)
           shadows.addReceiver(obj);
    }
