Plane defines an infinite plane in 3D space.
The equation of a plane is a*x + b*y + c*z = d, any point that satisfies this equation is on the plane.
| openstudio::Plane::Plane | ( | const Plane & | other | ) |
copy constructor
construct with point and outward normal, throws openstudio::Exception if outwardNormal has 0 length.
| openstudio::Plane::Plane | ( | const std::vector< Point3d > & | points | ) |
construct with points, will fit least squares plane.
attempts to align outward normal with that of the points (according to right hand rule). throws openstudio::Exception if cannot compute plane for these points.
