Detailed Description

template<size_t N>
class CubbyFlow::CustomScalarField< N >

N-D scalar field with custom field function.

Constructor & Destructor Documentation

CustomScalarField() [1/3]

template<size_t N>

CubbyFlow::CustomScalarField< N >::CustomScalarField	(	std::function< double(const Vector< double, N > &)>	customFunction,
		double	derivativeResolution = 1e-3
	)

Constructs a field with given function.

This constructor creates a field with user-provided function object. To compute derivatives, such as gradient and Laplacian, finite differencing is used. Thus, the differencing resolution also can be provided as the last parameter.

CustomScalarField() [2/3]

template<size_t N>

CubbyFlow::CustomScalarField< N >::CustomScalarField	(	std::function< double(const Vector< double, N > &)>	customFunction,
		std::function< Vector< double, N >(const Vector< double, N > &)>	customGradientFunction,
		double	derivativeResolution = 1e-3
	)

Constructs a field with given field and gradient function.

This constructor creates a field with user-provided field and gradient function objects. To compute Laplacian, finite differencing is used. Thus, the differencing resolution also can be provided as the last parameter.

CustomScalarField() [3/3]

template<size_t N>

CubbyFlow::CustomScalarField< N >::CustomScalarField	(	std::function< double(const Vector< double, N > &)>	customFunction,
		std::function< Vector< double, N >(const Vector< double, N > &)>	customGradientFunction,
		std::function< double(const Vector< double, N > &)>	customLaplacianFunction
	)

Constructs a field with given field, gradient, and Laplacian function.
