Detailed Description

template<int DIM>
class SAMRAI::appu::EmbeddedBoundaryShapePolygon< DIM >

Provides an analytic description of a convex polygon. It inherets from the EmbeddedBoundaryShape base class and provides a concrete implementation of the "isInside()" method, which specifies whether a cell is INSIDE the convex poly.

The user must specify at least three coordinates that define the vertices the poly. If the problem is 3D, a height must also be specified. An example input entry would look like:

 *        Polygon1{
 *           type = "POLYGON"
 *           coords_1 = 1.0 , 1.0
 *           coords_2 = 2.0 , 1.0
 *           coords_3 = 2.0 , 2.0
 *           coords_4 = 1.0 , 2.0
 *           height = 8.0
 *        }
 *

Member Function Documentation

template<int DIM>

bool SAMRAI::appu::EmbeddedBoundaryShapePolygon< DIM >::isInside

(

const double *

xyz

)

const [inline, virtual]

Concrete implementation of the isInside() method defined by the EmbeddedBoundaryShapeX base class. This method indicates whether the supplied xyz coordinates are inside or outside of the polygon.

Parameters:

xyz

double array[DIM] specifying coordinates.

Reimplemented from SAMRAI::appu::EmbeddedBoundaryShape< DIM >.

template<int DIM>

void SAMRAI::appu::EmbeddedBoundaryShapePolygon< DIM >::isInside	(	const int *	nx,
		const double *	dx,
		const double *	origin,
		int *	inout
	)			const [inline, virtual]

Concrete implementation of the isInside() method defined by the EmbeddedBoundaryShapeX base class. This method indicates whether the array of xyz coordinates are inside or outside of the polygon.

Parameters:

	nx	integer array [DIM] specifying number of points in each dir
	dx	double array [DIM] specifying spacing of points in each dir
	origin	double array [DIM] specifying origin of lower corner
	inout	int array dimensioned the total number of points (i.e. nx[0]*nx[1]*nx[2]). This is an OUTPUT quantity.

Reimplemented from SAMRAI::appu::EmbeddedBoundaryShape< DIM >.

template<int DIM>

void SAMRAI::appu::EmbeddedBoundaryShapePolygon< DIM >::printClassData

(

std::ostream &

os

)

const [virtual]

Dump data to supplied stream.

Implements SAMRAI::appu::EmbeddedBoundaryShape< DIM >.
