Typedef Documentation

Stored

template<class P >

using EBGeometry::CSGDetail::Stored = typedef typename StoredAs<P>::type

Shorthand for the type a BVH union stores for a primitive of type P.

Template Parameters

P	Primitive type.

Function Documentation

fromStored()

template<class P >

P EBGeometry::CSGDetail::fromStored ( const Stored< P > &  a_stored, const PoolLocation &  a_location  )

inlinenoexcept

The primitive a stored entry stands for, resolving against a_location.

A pool-resident primitive is rebuilt from its layout and the union's own location, so it resolves against the same pool the union does: the host pool, a host mirror or a device mirror. Any other primitive is returned as stored.

Template Parameters

P	Primitive type.

Parameters

[in]	a_stored	Primitive as stored in the union's BVH.
[in]	a_location	The union's pool location.

Returns

The primitive.

toStored()

template<class P >

Stored< P > EBGeometry::CSGDetail::toStored ( const P &  a_primitive )

inlinenoexcept

Convert a primitive to the form a BVH union stores.

Template Parameters

P	Primitive type.

Parameters

[in]

a_primitive

Primitive.

Returns

The primitive, or its layout if it is a pool-resident handle.
