Public Member Functions
constexpr	NeighborWindow ()=default
	Default window: no floor, at most two bins per axis.
constexpr	NeighborWindow (std::array< std::uint8_t, 2 > windowMin, std::array< std::uint8_t, 2 > windowMax)
	Window with an explicit floor and bound per axis.
constexpr	NeighborWindow (std::uint8_t maxNeighborDistance)
	Isotropic window: at least one bin unless the bound forbids it, at most maxNeighborDistance.

Public Attributes
std::array< std::uint8_t, 2 >	max = {2, 2}
	Most bins served in each direction; also sizes the neighbor cache.
std::array< std::uint8_t, 2 >	min = {0, 0}
	Fewest bins served in each direction, regardless of the crossing angle.

Detailed Description

Bounds on the neighbor window, in bins per grid axis.

The floor serves lookups that cannot see the surfaces the fill saw, e.g. under alignment.

Constructor & Destructor Documentation

NeighborWindow() [1/2]

Acts::SurfaceArray::NeighborWindow::NeighborWindow ( std::array< std::uint8_t, 2 > windowMin, std::array< std::uint8_t, 2 > windowMax )

constexpr

Window with an explicit floor and bound per axis.

Parameters

windowMin	Fewest bins served in each direction
windowMax	Most bins served in each direction

NeighborWindow() [2/2]

Acts::SurfaceArray::NeighborWindow::NeighborWindow ( std::uint8_t maxNeighborDistance )

constexpr

Isotropic window: at least one bin unless the bound forbids it, at most maxNeighborDistance.

Deprecated

The two axes of a layer grid are not equivalent, give the bounds per axis.

Parameters

maxNeighborDistance

Most bins served in each direction
