template<typename Derived>
class BaseDenseGrid2 : public beluga::BaseRegularGrid<Derived>

Dense 2D grid base type.

When instantiated, it satisfies Beluga named requirements: DenseGrid2.

Template Parameters:

Derived – Concrete dense grid type. It must define Derived::width(), Derived::height(), Derived::resolution(), Derived::data_at(index), and Derived::index_at(int, int) as described in Beluga named requirements: DenseGrid2.

Subclassed by beluga::BaseLinearGrid2< ValueGrid2< T > >, beluga::BaseLinearGrid2< ValueGrid2< float > >, beluga::BaseLinearGrid2< Derived >

Public Functions

inline bool contains(int xi, int yi) const

Checks if a cell is included in the grid.

Parameters:

  • xi – Grid cell x-axis coordinate.

  • yi – Grid cell y-axis coordinate.

inline bool contains(const Eigen::Vector2i &pi) const

Checks if a cell is included in the grid.

Parameters:

pi – Grid cell coordinates.

inline auto data_at(int xi, int yi) const

Gets cell data, if included.

Parameters:

  • xi – Grid cell x-axis coordinate.

  • yi – Grid cell y-axis coordinate.

Returns:

Cell data if included, std::nullopt otherwise.

inline auto data_at(const Eigen::Vector2i &pi) const

Gets cell data, if included.

Parameters:

pi – Grid cell coordinates.

Returns:

Cell data if included, std::nullopt otherwise.

inline auto data_near(double x, double y) const

Gets nearest cell data, if included.

Parameters:

  • x – Plane x-axis coordinate.
