- FMETriangleFan.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 in
isPlanar(). 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 to
False, the passed in value of D will be used in the calculation. If ‘recalcualteD’ is set to
True, 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’ to
True, and then use this value for future calls with ‘recalculateD’ to
- Return type
A tuple containing a boolean, tuple, and float representing: 1) Whether or not the surface 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).
