Detailed Description

2-D Vertex-centered scalar grid structure.

This class represents 2-D vertex-centered scalar grid which extends ScalarGrid2. As its name suggests, the class defines the data point at the grid vertices (corners). Thus, A x B grid resolution will have (A+1) x (B+1) data points.

Constructor & Destructor Documentation

◆ VertexCenteredScalarGrid2() [1/4]

CubbyFlow::VertexCenteredScalarGrid2::VertexCenteredScalarGrid2 ( )

Constructs zero-sized grid.

◆ VertexCenteredScalarGrid2() [2/4]

CubbyFlow::VertexCenteredScalarGrid2::VertexCenteredScalarGrid2 ( 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.

◆ VertexCenteredScalarGrid2() [3/4]

CubbyFlow::VertexCenteredScalarGrid2::VertexCenteredScalarGrid2 ( 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.

◆ VertexCenteredScalarGrid2() [4/4]

CubbyFlow::VertexCenteredScalarGrid2::VertexCenteredScalarGrid2 ( const VertexCenteredScalarGrid2 other)

Copy constructor.

Member Function Documentation

◆ Clone()

std::shared_ptr<ScalarGrid2> CubbyFlow::VertexCenteredScalarGrid2::Clone ( ) const
overridevirtual

Returns the copy of the grid instance.

Implements CubbyFlow::ScalarGrid2.

◆ GetBuilder()

static Builder CubbyFlow::VertexCenteredScalarGrid2::GetBuilder ( )
static

Returns builder fox VertexCenteredScalarGrid2.

◆ GetDataOrigin()

Vector2D CubbyFlow::VertexCenteredScalarGrid2::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::VertexCenteredScalarGrid2::GetDataSize ( ) const
overridevirtual

Returns the actual data point size.

Implements CubbyFlow::ScalarGrid2.

◆ operator=()

VertexCenteredScalarGrid2& CubbyFlow::VertexCenteredScalarGrid2::operator= ( const VertexCenteredScalarGrid2 other)

Sets the contents with the given other grid.

◆ Set()

void CubbyFlow::VertexCenteredScalarGrid2::Set ( const VertexCenteredScalarGrid2 other)

Sets the contents with the given other grid.

◆ Swap()

void CubbyFlow::VertexCenteredScalarGrid2::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.
