Multi-fidelity API
register_fidelity({f1:continuous[0..1], f2:discrete[hier,prog]});
hint_resource(CPU, (f2 == hier) ? 1.4 nf1log(nf1) : 2 n2f12);
hint_constraint(LATENCY, 0.05 seconds);
When the user requests a coloring operation
begin_fidelity_op(1000 input data size in polygons);returns {f1=0.4, f2=hier} values of fidelity metrics
� run the radiosity computation �
end_fidelity_op(); signals end of interactive computation
