Detailed Description

template<typename T, ind N, typename Vec = std::array<T, N>>
class inviwo::discretedata::AnalyticChannel< T, N, Vec >

Data channel by function evaluated at each (linear) index.

Realization of DataChannel.

Data is stored implicitly by a function f:index -> vec<T, N>, where the destination memory is pre-allocated. Indices are linear.

Author: Anke Friederici and Tino Weinkauf

Constructor & Destructor Documentation

◆ AnalyticChannel()

template<typename T , ind N, typename Vec = std::array<T, N>>

inviwo::discretedata::AnalyticChannel< T, N, Vec >::AnalyticChannel	(	Function	dataFunction,
		ind	numElements,
		const std::string &	name,
		GridPrimitive	definedOn = `GridPrimitive::Vertex`
	)

inline

Direct construction.

Parameters

dataFunction	Data generator, mapping of linear index to T*
numElements	Total number of indexed positions
name	Name associated with the channel
definedOn	GridPrimitive the data is defined on, default: 0D vertices
