◆ addGhosts()

virtual void BooleanDomain::addGhosts	(	ArrayView< const Vector >	vs,
		Array< Ghost > &	ghosts,
		const Float	eta,
		const Float	eps
	)		const

inlineoverridevirtual

Duplicates positions located close to the boundary, placing copies ("ghosts") symmetrically to the other side of the domain.

Distance of the copy (ghost) to the boundary shall be the same as the source vector. One vector can create multiple ghosts.

Parameters

vs	Array containing vectors creating ghosts.
ghosts	Output parameter containing created ghosts, stored as pairs (position of ghost and index of source vector). Array must be cleared by the function!
eta	Dimensionless distance to the boundary necessary for creating a ghost. A ghost is created for vector v if it is closer than radius * v[H]. Vector must be inside, outside vectors are ignored.
eps	Minimal dimensionless distance of ghost from the source vector. When vector is too close to the boundary, the ghost would be too close or even on top of the source vector; implementation must place the ghost so that it is outside of the domain and at least eps * v[H] from the vector. Must be strictly lower than radius, checked by assert.

Todo:: this is not correct, do properly

Implements IDomain.

Definition at line 626 of file GeometryJobs.cpp.

◆ contains()

virtual bool BooleanDomain::contains ( const Vector & v ) const

inlineoverridevirtual

Checks if the given point lies inside the domain.

Points lying exactly on the boundary of the domain are assumed to be inside.

Implements IDomain.

Definition at line 578 of file GeometryJobs.cpp.

◆ getBoundingBox()

virtual Box BooleanDomain::getBoundingBox ( ) const

inlineoverridevirtual

Returns the bounding box of the domain.

Implements IDomain.

Definition at line 551 of file GeometryJobs.cpp.

◆ getCenter()

virtual Vector BooleanDomain::getCenter ( ) const

inlineoverridevirtual

Returns the center of the domain.

Implements IDomain.

Definition at line 547 of file GeometryJobs.cpp.

◆ getDistanceToBoundary()

virtual void BooleanDomain::getDistanceToBoundary	(	ArrayView< const Vector >	vs,
		Array< Float > &	distances
	)		const

inlineoverridevirtual

Returns distances of particles lying close to the boundary.

The distances are signed, negative number means the particle is lying outside of the domain. Distances can be computed with small error to simplify implementation.

Parameters

vs	Input array of points.
distances	Output array, will be resized to the size of particle array and cleared.

Todo:: unify the (non)clearing of output arrays

Implements IDomain.

Definition at line 612 of file GeometryJobs.cpp.

◆ getSubset()

virtual void BooleanDomain::getSubset	(	ArrayView< const Vector >	vs,
		Array< Size > &	output,
		const SubsetType	type
	)		const

inlineoverridevirtual

Returns an array of indices, marking vectors with given property by their index.

Parameters

vs	Input array of points.
output	Output array, is not cleared by the method, previously stored values are kept unchanged. Indices of vectors belonging in the subset are pushed into the array.
type	Type of the subset, see SubsetType.

Implements IDomain.

Definition at line 592 of file GeometryJobs.cpp.

◆ getSurfaceArea()

virtual Float BooleanDomain::getSurfaceArea ( ) const

inlineoverridevirtual

Returns the surface area of the domain.

Implements IDomain.

Definition at line 573 of file GeometryJobs.cpp.

◆ getVolume()

virtual Float BooleanDomain::getVolume ( ) const

inlineoverridevirtual

Returns the total volume of the domain.

This should be identical to computing an integral of isInside function, although faster and more precise.

Implements IDomain.

Definition at line 569 of file GeometryJobs.cpp.

◆ project()

virtual void BooleanDomain::project	(	ArrayView< Vector >	vs,
		Optional< ArrayView< Size >>	indices
	)		const

inlineoverridevirtual

Projects vectors outside of the domain onto its boundary.

Vectors inside the domain are untouched. Function does not affect 4th component of vectors.

Parameters

vs	Array of vectors we want to project
indices	Optional array of indices. If passed, only selected vectors will be projected. All vectors are projected by default.

Todo:: this is not correct, do properly

Implements IDomain.
