fmeobjects.FMEEllipse.isInPlane
- FMEEllipse.isInPlane(tolerance, normalVector, valD, recalculateD)
Works similarly to
isPlanar()
, but checks planarity with respect to given normal or given plane (if plane equation D is specified - see below). If given normal is the zero vector, the normal used to check the planarity is computed using Newell’s method as inisPlanar()
. valD is a reference to a value of D in the plane equation AX + BY + CZ = D. It can be used to make sure that multiple pieces lie in the same plane. If ‘recalculateD’ is set toFalse
, the passed in value of D will be used in the calculation. If ‘recalcualteD’ is set toTrue
, the passed in value is ignored and is instead automatically calculated (and returned in the second position of the returned tuple). A useful calling pattern for ensuring co-planarity is to get valD computed on the first call to the function setting recalculateD toTrue
, and then use this value for future calls with recalculateD toFalse
.- Parameters:
- Return type:
- Returns:
A tuple containing a boolean, tuple, and float representing: 1) Whether or not the area is in plane; 2) The normal vector returned; and 3) The value ‘D’. Note: If recalculateD is
False
, the tuple returned will only contain the boolean and vector tuple (i.e. ‘valD’ is not returned).
