This contribution reports the simulation results of EE2 Test 1.15. In Test 1.15, two new additional planar modes are proposed where only the horizontal interpolation or only the vertical interpolation are used to obtain the predicted samples. It is reported that on top of ECM-6.0, the overall coding performance impact for {Y, U, V, EncT, DecT} are {-0.08%, 0.06%, 0.06%, 115%, 100%} for AI and {-0.03%, 0.02%, -0.04%, 102%, 100%} for RA.
