Detailed Description

A struct to access generated vertices from surface polyhedrons These vertices are then used to find the bin boundary box for the indexed grid.

The grid filling then completes the empty bins in between and expands if necessary.

◆ references()

const std::vector< Vector3 > Acts::PolyhedronReferenceGenerator::references	(	const GeometryContext &	gctx,
		const Surface &	surface ) const

overridevirtual

Helper to access the Center point of for filling the grid.

Parameters

gctx	the geometry context of this operation
surface	the surface for which the reference point is to be accessed

Returns: a vector of reference points for filling

Implements Acts::IReferenceGenerator.
