Detailed Description

Adaptor exposing a 2D point cloud to nanoflann.

This class provides the minimal interface required by nanoflann to access a set of 2D points stored as separate x and y coordinate arrays.

The data is not owned by the adaptor; it references external vectors.

Constructor & Destructor Documentation

NanoflannPointCloudAdaptor()

hmap::NanoflannPointCloudAdaptor::NanoflannPointCloudAdaptor	(	const std::vector< float > &	x_,
		const std::vector< float > &	y_
	)

Construct the adaptor from coordinate arrays.

Parameters

x_	Vector of x coordinates
y_	Vector of y coordinates
