Detailed Description

2-D Cell-centered scalar grid structure.

This class represents 2-D cell-centered scalar grid which extends ScalarGrid2. As its name suggests, the class defines the data point at the center of a grid cell. Thus, the dimension of data points are equal to the dimension of the cells.

Constructor & Destructor Documentation

◆ CellCenteredScalarGrid2() [1/4]

CubbyFlow::CellCenteredScalarGrid2::CellCenteredScalarGrid2 ( )

Constructs zero-sized grid.

◆ CellCenteredScalarGrid2() [2/4]

CubbyFlow::CellCenteredScalarGrid2::CellCenteredScalarGrid2	(	size_t	resolutionX,
		size_t	resolutionY,
		double	gridSpacingX = `1.0`,
		double	gridSpacingY = `1.0`,
		double	originX = `0.0`,
		double	originY = `0.0`,
		double	initialValue = `0.0`
	)

Constructs a grid with given resolution, grid spacing, origin and initial value.

◆ CellCenteredScalarGrid2() [3/4]

CubbyFlow::CellCenteredScalarGrid2::CellCenteredScalarGrid2	(	const Size2 &	resolution,
		const Vector2D &	gridSpacing = `Vector2D(1.0, 1.0)`,
		const Vector2D &	origin = `Vector2D()`,
		double	initialValue = `0.0`
	)

Constructs a grid with given resolution, grid spacing, origin and initial value.

◆ CellCenteredScalarGrid2() [4/4]

CubbyFlow::CellCenteredScalarGrid2::CellCenteredScalarGrid2 ( const CellCenteredScalarGrid2 & other )

Copy constructor.

Member Function Documentation

◆ Clone()

std::shared_ptr<ScalarGrid2> CubbyFlow::CellCenteredScalarGrid2::Clone ( ) const

overridevirtual

Returns the copy of the grid instance.

Implements CubbyFlow::ScalarGrid2.

◆ GetBuilder()

static Builder CubbyFlow::CellCenteredScalarGrid2::GetBuilder ( )

static

Returns builder fox CellCenteredScalarGrid2.

◆ GetDataOrigin()

Vector2D CubbyFlow::CellCenteredScalarGrid2::GetDataOrigin ( ) const

overridevirtual

Returns data position for the grid point at (0, 0). Note that this is different from origin() since origin() returns the lower corner point of the bounding box.

Implements CubbyFlow::ScalarGrid2.

◆ GetDataSize()

Size2 CubbyFlow::CellCenteredScalarGrid2::GetDataSize ( ) const

overridevirtual

Returns the actual data point size.

Implements CubbyFlow::ScalarGrid2.

◆ operator=()

CellCenteredScalarGrid2& CubbyFlow::CellCenteredScalarGrid2::operator= ( const CellCenteredScalarGrid2 & other )

Sets the contents with the given other grid.

◆ Set()

void CubbyFlow::CellCenteredScalarGrid2::Set ( const CellCenteredScalarGrid2 & other )

Sets the contents with the given other grid.

◆ Swap()

void CubbyFlow::CellCenteredScalarGrid2::Swap ( Grid2 * other )

overridevirtual

Swaps the contents with the given other grid.

This function swaps the contents of the grid instance with the given grid object other only if other has the same type with this grid.

Implements CubbyFlow::Grid2.
