Detailed Description

template<int dim, class SourceSwarm, class TargetSwarm>
class Portage::SearchPointsByCells< dim, SourceSwarm, TargetSwarm >

A simple, crude search algorithm that does a linear-time search over a swarm of points.

Template Parameters

SourceSwarm	The swarm type of the input swarm.
TargetSwarm	The swarm type of the output swarm.

inline

Builds the search structure for finding neighboring points.

Parameters

[in]	source_swarm	Pointer to source swarm info.
[in]	target_swarm	Pointer to target swarm info.
[in]	source_extents	Array of extents for source particles.
[in]	target_extents	Array of extents for target particles.

Constructor for search structure for finding points from a source swarm that are near points in the target swarm.

operator()()

template<int dim, class SourceSwarm , class TargetSwarm >

std::vector<int> Portage::SearchPointsByCells< dim, SourceSwarm, TargetSwarm >::operator() ( int  pointId ) const

inline

Find the source swarm points within an appropriate distance of a target point.

Parameters

[in]	pointId	The index of the point in the target swarm for which we wish to find the candidate neighbor points in the source swarm.
[in,out]	candidates	Pointer to a vector of potential candidate points in the source swarm.
