Detailed Description

Build a region of intersecting surfaces as a CSG node.

This is the building block for constructing shapes, solids, and so forth. The result of this class is:

CSG nodes describing the inserted surfaces which have been transformed into the global reference frame
Metadata combining the surfaces names with the object name
Bounding boxes (interior and exterior)

Internally, this class uses:

SurfaceClipper to update bounding boxes for closed quadric surfaces (axis aligned cylinders, spheres, planes)
apply_transform (which calls detail::SurfaceTransformer and its siblings) to generate new surfaces based on the local transformed coordinate system
RecursiveSimplifier to take transformed or user-input surfaces and reduce them to more compact quadric representations

Constructor & Destructor Documentation

◆ IntersectSurfaceBuilder()

celeritas::orangeinp::IntersectSurfaceBuilder::IntersectSurfaceBuilder	(	UnitBuilder *	ub,
		State *	state
	)

Construct with persistent unit builder and less persistent state.

Both arguments must have lifetimes that exceed the surface builder, but the "unit builder" will have a duration of the whole unit construction, whereas the state just has the duration of the surface set being built.

Member Function Documentation

◆ operator()() [1/3]

void celeritas::orangeinp::IntersectSurfaceBuilder::operator()	(	Sense	sense,
		BBox const &	bbox
	)

inline

Promise that all bounding surfaces are inside/outside this bbox.

"inside" will shrink the exterior bbox, and "outside" will grow the interior bbox. All bounding surfaces within the region must be inside the exterior region and outside the interior region.

◆ operator()() [2/3]

template<class S >

void celeritas::orangeinp::IntersectSurfaceBuilder::operator()	(	Sense	sense,
		S const &	surf
	)

Add a surface with a sense.

The resulting surface MUST result in a intersect region.
