Class ValueFunctionRenderLayer

java.lang.Object

burlap.behavior.singleagent.auxiliary.valuefunctionvis.ValueFunctionRenderLayer

All Implemented Interfaces:

RenderLayer

public class ValueFunctionRenderLayer
extends java.lang.Object
implements RenderLayer

Used to visualize the value function for a collection of states. This class makes use of the StateValuePainter StatePolicyPainter and StaticDomainPainter to paint the value function. Each state is iterated over and the the respective classes are used to pain its value function. The visualizer requires a QComputablePlanner to retrieve the value function.
