Detailed Description

template<size_t dim>
class mc::domains::IntegrationDomain< dim >

Abstract base class for N-dimensional integration domains.

Template Parameters

dim	Dimensionality of the domain

Provides the interface required by Monte Carlo integrators to sample and evaluate points within geometric regions. All domain types must implement bounding box, volume, and point containment queries.

Note

This is a pure virtual interface requiring concrete implementations.

Virtual destructor for proper cleanup of derived classes.

Member Function Documentation

getBounds()

template<size_t dim>

virtual mc::geom::Bounds< dim > mc::domains::IntegrationDomain< dim >::getBounds ( ) const

pure virtual

Get the axis-aligned bounding box of the domain.

Returns

Bounds object containing min/max extents along each axis

Used by samplers to generate candidate points uniformly within a hyperrectangle enclosing the actual domain.

Implemented in DroneArmDomain, mc::domains::HyperCylinder< dim >, mc::domains::HyperRectangle< dim >, mc::domains::Hypersphere< dim >, and mc::domains::PolyTope< dim >.

getBoxVolume()

template<size_t dim>

virtual double mc::domains::IntegrationDomain< dim >::getBoxVolume ( ) const

pure virtual

Compute the volume of the bounding box.

Returns

Volume of the hyperrectangular bounding region

Required for acceptance-rejection sampling and Hit-or-Miss volume estimation. Returns the product of extents along all axes.

Implemented in DroneArmDomain, mc::domains::HyperCylinder< dim >, mc::domains::HyperRectangle< dim >, mc::domains::Hypersphere< dim >, and mc::domains::PolyTope< dim >.

isInside()

template<size_t dim>

virtual bool mc::domains::IntegrationDomain< dim >::isInside ( const mc::geom::Point< dim > &  point ) const

pure virtual

Test whether a point lies inside the domain.

Parameters

point

Point to test

Returns

true if point ∈ domain, false otherwise

This is the core containment predicate used during Monte Carlo sampling. Should be implemented efficiently as it's called millions of times.

Implemented in mc::domains::HyperCylinder< dim >, mc::domains::PolyTope< dim >, mc::domains::HyperRectangle< dim >, and mc::domains::Hypersphere< dim >.
