Function Documentation

float planeEq (  int    q1, int    q2, int    q3, float    n1, float    n2, float    n3 )  [inline]

Calculates if point Q lies on plane with normal N. See also: calculateCuttingPlane() Parameters: q1  q2 q3 Coordinates of point Q, Q=<q1,q2,q3> n1  n2 n3 Components of normal vector, N=<n1,n2,n3> This function calculates if point Q lies on plane N and returns 0 if it is on the plane, <0 if it is less than, >0 if greater than.
