+ *      
+ *      //setting the water plane
+ *      Vector3f waterLocation=new Vector3f(0,-20,0);
+ *      waterProcessor.setPlane(new Plane(Vector3f.UNIT_Y, waterLocation.dot(Vector3f.UNIT_Y)));
+ *      //setting the water color 
+ *      waterProcessor.setWaterColor(ColorRGBA.Brown);
+ *
+ *      //creating a quad to render water to
+ *      Quad quad = new Quad(400,400);
+ *
+ *      //the texture coordinates define the general size of the waves
+ *      quad.scaleTextureCoordinates(new Vector2f(6f,6f));
+ *
+ *      //creating a geom to attach the water material

+ *      water.setLocalRotation(new Quaternion().fromAngleAxis(-FastMath.HALF_PI, Vector3f.UNIT_X));
