Detailed Description

Abstract wrapper of a grid.

Member Function Documentation

virtual std::auto_ptr<GeometryFactory> Bempp::Grid::elementGeometryFactory ( ) const

pure virtual

Factory able to construct empty geometries of codimension 0 compatible with this grid.

void Bempp::Grid::getBoundingBox	(	arma::Col< double > &	lowerBound,
		arma::Col< double > &	upperBound
	)		const

Get bounding box.

The grid lies in the box defined by the inequalities lowerBound(i) <= x_i <= upperBound(i), where x_i is the ith coordinate.

Referenced by maxDistance().

virtual int Bempp::Grid::maxLevel ( ) const

pure virtual

Maximum level defined in this grid.

Levels are numbered 0 ... maxLevel() with 0 the coarsest level.

Parameters

[in]	grid	A grid representing a closed 2D surface embedded in a 3D space.
[in]	points	A 2D array of dimensions (3, `n`) whose (`i`, `j`)th element is the `i'th` coordinate of `j'th` point.

Returns: A vector of length n whose j'th element is true if the j'th point lies inside grid, false otherwise.

Note: The results produced by this function are undefined if the grid does not represent a closed surface.; This function has only been tested for triangular grids.; The implementation assumes that no grid vertices are separated by less than 1e-9.

Note: The returned number is an upper bound rather than an exact value (it is calculated from the bounding boxes of the two grids)
