virtual void FEAT::Geometry::VoxelMasker< MeshType::CoordType , dim_ >::mask_line ( std::vector< int > &  mask, const CoordType  x_min, const CoordType  x_max, const PointType &  point  )

pure virtualinherited

Computes the mask for an entire X-coordinate row.

This function is called by the VoxelMap class to perform the inside/outside-test for a line of points with common Y/Z coordinates, where the X coordinates of the points have to be computed from the X-coordinate range and the number points by calling the x_coord helper function.

Attention

This function must be implemented in a thread-safe fashion, since the VoxelMap class makes use of OpenMP parallelization to speed up the map computation time.

Parameters

[in,out]	mask	The mask vector for the current X-row. Is allocated to correct size, but its contents are undefined upon entry. Assuming that the length of this vector is n, then the i-th entry of the mask vector is to be set to 1 if the point with the X-coordinate equal to x_coord(x_min, x_max, i, mask.size()) is inside the mask, otherwise it is to be set to 0.
[in]	x_min,x_max	The minimal and maximal X-coordinate of the X-line for which the mask is to be computed.
[in]	point	The point that contains the Y- and (in 3D) Z-coordinates of the X-line that for which the mask is to be computed. The first coordinate, i.e. point[0], is undefined, so only point[1] and (in 3D) point[2] are set to the Y-/Z-coords.

x_coord()

static CoordType FEAT::Geometry::VoxelMasker< MeshType::CoordType , dim_ >::x_coord ( const CoordType  x_min, const CoordType  x_max, const std::size_t  i, const std::size_t  n  )

inlinestaticinherited

Computes the X-coordinate for a given point.

This helper function can be used by derived classes to compute the X-coordinate for a single point on the mask line.

Parameters

[in]	x_min,x_max	The minimal and maximal X-coordinate of the X-line for which the mask is to be computed.
[in]	i	The index of the current point in the X-line that is being tested
[in]	n	The number of points in the line; corresponds to mask.size()

Returns

The X-coordinate of the current point
