This templated class represents a quadric surface.
| Util::Quadric< Dim >::Quadric | ( | void | ) |
The default constructor sets the quadric to the zero function.
| Util::Quadric< Dim >::Quadric | ( | const Matrix< Dim, Dim > & | Q, |
| const Point< Dim > & | L, | ||
| const double & | C | ||
| ) |
Constructs a quadric with the prescribed quadratic, linear, and constant terms. (The quadric's matrix is set to the average of Q and its transpose.)
| Util::Quadric< Dim >::Quadric | ( | const Matrix< Dim+1, Dim+1 > & | Q | ) |
Constructs a quadric with the prescribed matrix.
| double Util::Quadric< Dim >::getConstant | ( | void | ) | const |
This method returnsthe quadric's constant term.
| Point< Dim > Util::Quadric< Dim >::getLinear | ( | void | ) | const |
This method returns (half) the quadric's linear term.
| Matrix< Dim, Dim > Util::Quadric< Dim >::getQuadratic | ( | void | ) | const |
This method returns the quadric's quadratic term.
| Quadric< 1 > Util::Quadric< Dim >::intersect | ( | const Ray< Dim > & | ray | ) | const |
This method returns the one-dimensional quadric obtained by restricting the Dim-dimensional quadratic to the ray.
| double Util::Quadric< Dim >::operator() | ( | const Point< Dim > & | p | ) | const |
This method returns the evaluation of the quadric at a prescribed point.
| SquareMatrix< Dim+1 > Util::Quadric< Dim >::operator() | ( | void | ) | const |
This method returns the quadric as a homogenous matrix.
| Quadric< _Dim > Util::Quadric< Dim >::operator* | ( | const Matrix< Dim, _Dim > & | T | ) | const |
This method returns the quadric in _Dim dimensions obtained by transforming this quadric. The evaluation of the new quadric at the point p is the value of the original quadric at the point T*p.
| Quadric< Dim > Util::Quadric< Dim >::operator+ | ( | const Point< Dim > & | t | ) | const |
This method returns the translated quadric. The evaluation of the translated quadric at the point p is the value of the original quadric at the point p+t
| void Util::Quadric< Dim >::setConstant | ( | double | C | ) |
This method sets the linear term
| bool Util::Quadric< Dim >::setExtremum | ( | Point< Dim > & | extremum | ) | const |
This method sets the extremum of the quadric. As it is possible for the extremum not to be unique (e.g. for a cylinder), this method will return a boolean value indicating if the setting of the extremum was successfull.
| void Util::Quadric< Dim >::setLinear | ( | Point< Dim > | L | ) |
This method sets the (half) linear term
| void Util::Quadric< Dim >::setQuadratic | ( | Matrix< Dim, Dim > | Q | ) |
This method sets the quadratic term
