STEP 3: Diagonal Waves

 

float wave_macro = getWave(s, macro_freq, phase, macro_chop, p);

float wave_micro = getWave(s*t, macro_freq, phase, micro_chop, p);

hump = wave_macro + wave_micro;
P = P - n * hump * Km;
N = calculatenormal(P);

A second set of waves added, this time moving diagonally from the bottom corner.
