Public Attributes
T	m_value

	The point the leaf was evaluated at.

Detailed Description

template<class T>
struct EBGeometry::CSGOps::Tagged< T >

A value with the deciding leaf it comes from: the leaf whose surface the composed value is taken from there, and the point that leaf was evaluated at (in its own frame).

The operations below work on a plain value T and on a Tagged<T> alike. On a Tagged<T> they compute the value as on a T and carry the tag of the operand the value comes from (see Tape::closestPrimitive()).

Template Parameters

T	Floating-point precision.

m_tag

template<class T >

uint32_t EBGeometry::CSGOps::Tagged< T >::m_tag

The deciding leaf, as the structure numbers it (NoTag for none).

No default member initializer: the tape keeps a fixed stack of values, and one would write every slot of it on every evaluation (a tagged float tape on a GPU was 59% slower). A value that names no leaf is made with noLeaf().
