Hi, Can you tell me the mean of MAX() and MIN() in this expression?
alpha = M_PI/2. - acos(MAX(-1.,MIN(1.,NV_DOT(normal,p->state.V)/MAX(NV_MAG(p->state.V),DPM_SMALL)))); |

MAX(x,y)=
x if x>y y if y>x MIN(x,y)= y if x>y x if y>x |

MAX is maximum and MIN is minimum.
Actually this function compares its arguments and return the maximum/minimum value. |
