Detailed Description

template<class T>
struct EBGeometry::RayDetail::GrownRayQuery< T >

A BVH ray query whose boxes are grown by a radius: what a mesh's offset faces are walked with.

Internal helper; not part of the public API. Growing [lo, hi] by g moves each axis's slab distances by g / |direction component| outward.

Template Parameters

T	Floating-point precision.

Constructor & Destructor Documentation

GrownRayQuery()

template<class T >

The query along a ray.

Parameters
