Detailed Description

template<class Real>
struct peclet::core::geom::SceneQueryView< Real >

The one POD every consumer captures: sphere-union fast path when the scene is a plain sphere union, general scene otherwise, candidate-accelerated in both modes, min-image periodic.

Mode selection happens ONCE at build (SceneQueryDevice / SceneQueryHost), so numerics are deterministic per scene; the sphere path is fma-canonical (bitwise host==device), the general tree walk is judged by the sign+ULP rule across backends.

◆ evalOwner()

template<class Real >

PECLET_HD Real peclet::core::geom::SceneQueryView< Real >::evalOwner	(	Vec3< Real >	p,
		int &	own
	)		const

inline

eval(p) AND the index of the instance (sphere-union mode: the sphere) whose surface is nearest — the argmin behind eval's min, in ONE traversal.

own is -1 for an empty scene. Ties break to the lowest index; see the determinism contract above. The returned value is bitwise eval's, so a consumer that needs both never has to reconcile two numbers.
