Constructor & Destructor Documentation

SweepAndPrune() [1/2]

pbat::gpu::geometry::SweepAndPrune::SweepAndPrune	(	std::size_t	nPrimitives,
		std::size_t	nOverlaps )

Construct a new Sweep And Prune object with space allocated for nPrimitives and at most nOverlaps.

Parameters

nPrimitives	Number of primitives
nOverlaps	Maximum number of overlaps

SweepAndPrune() [2/2]

pbat::gpu::geometry::SweepAndPrune::SweepAndPrune ( SweepAndPrune && other )

noexcept

Move constructor.

Parameters

other

SweepAndPrune to move from

Member Function Documentation

operator=()

SweepAndPrune & pbat::gpu::geometry::SweepAndPrune::operator= ( SweepAndPrune && other )

noexcept

Move assignment.

Parameters

other

SweepAndPrune to move from

Returns

Reference to this

SortAndSweep() [1/2]

GpuIndexMatrixX pbat::gpu::geometry::SweepAndPrune::SortAndSweep

(

Aabb &

aabbs

)

Detect overlaps between the AABBs.

Parameters

aabbs

Handle to the AABBs

Returns

2 x |# overlaps| matrix of overlap pairs in aabbs

SortAndSweep() [2/2]

PBAT_API GpuIndexMatrixX pbat::gpu::geometry::SweepAndPrune::SortAndSweep	(	common::Buffer const &	set,
		Aabb &	aabbs )

Detect overlaps between the AABBs of different sets.

Parameters

set	|# aabbs| map of indices of aabbs to their corresponding set, i.e. set[i] = j means that aabb i belongs to set j. Must be a 1D Buffer of type GpuIndex of the same size as aabbs.
aabbs	The AABBs over objects

Returns

2x|# overlaps| matrix of overlap pairs between boxes of different sets
