Detailed Description

template<class Real, class MemSpace = typename Kokkos::DefaultExecutionSpace::memory_space>
class peclet::core::geom::SceneQueryDevice< Real, MemSpace >

Owns everything a SceneQueryView needs on ONE memory space: the DeviceScene, the extracted sphere-union arrays when the scene is a plain sphere union (mode selected ONCE, here), the candidate-grid CSR, and the periodicity.

flow's set_scene, the resolved-CFD-DEM coupling and the AMR device builders are meant to hold one of these instead of private uploads.

build()

template<class Real , class MemSpace = typename Kokkos::DefaultExecutionSpace::memory_space>

static SceneQueryDevice peclet::core::geom::SceneQueryDevice< Real, MemSpace >::build ( const SceneBuilder< Real > &  b, Vec3< Real >  origin, Vec3< Real >  extent, PeriodicBox< Real >  box, bool  accelerate = true, int  nbHint = 0  )

inlinestatic

Build from a host SceneBuilder.

origin/extent bound the candidate grid's coverage (queries outside fall back to full scans — exact); accelerate=false skips the grid (right for a handful of instances, e.g. a single stirrer).
