Detailed Description

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

N-D vector field with custom field function.

Constructor & Destructor Documentation

CustomVectorField() [1/3]

template<size_t N>

CubbyFlow::CustomVectorField< N >::CustomVectorField	(	std::function< Vector< double, N >(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.

CustomVectorField() [2/3]

template<size_t N>

CubbyFlow::CustomVectorField< N >::CustomVectorField	(	std::function< Vector< double, N >(const Vector< double, N > &)>	customFunction,
		std::function< double(const Vector< double, N > &)>	customDivergenceFunction,
		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.

CustomVectorField() [3/3]

template<size_t N>

CubbyFlow::CustomVectorField< N >::CustomVectorField	(	std::function< Vector< double, N >(const Vector< double, N > &)>	customFunction,
		std::function< double(const Vector< double, N > &)>	customDivergenceFunction,
		std::function< typename GetCurl< N >::Type(const Vector< double, N > &)>	customCurlFunction
	)

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