		std::array< double, 3 > *	projectionNormal ) const

overrideprotectedvirtual

Evaluate the projection of the given point on the surface created based on the points representing the specified segment. The surface passes from these points and is verical to the normal vectors associated with them.

If the usage of an unsigned level set is requested, the orientation of the surface should be discarded in order to have a normal that is agnostic with respect to the two sides of the surface. If the sign is not cached, it should be evaluated from scratch and this will cause the projection evaluation to be performed twice.

Parameters

[in]	point	are the coordinates of the given point
[in]	signedLevelSet	controls if signed levelset function will be used
[out]	projectionPoint	The coordinates of the projection point on the surface.
[out]	projectionNormal	The coordinates of the norrmal to the surface vector on the surface projection point.

		bool	invert,
		std::array< std::array< double, 3 >, 2 > *	intersection,
		std::vector< std::array< double, 3 > > *	polygon ) const

overrideprotectedvirtual

Check if the specified interface intersects the zero-levelset iso-surface.

The iso-surface is considered planar. Calculate the intersection as a segment defined by two points and the part of the interface belonging to the subspace of negative level-set. If the interface is not intersected, an empty polygon is returned. The interface belonging to the possitive level-set subspace is returned if the "invert" argument is false.

Depending on the smoothing order, the intersection is computed by considering the zero-levelset as a plane or a curved surface.

Parameters

[in]	id	is the interface index
[in]	invert	when false the part of the interface occupying the positive levelset area is returned
[out]	intersection	If intersects, return the cutting segment. In case of a liner interface the intersection degenerates to a point which coincides with the begining and the ending of the segment
[out]	polygon	is the polygon constructed by the interface intersection placed on the opposite subspace of the one pointed by the plane's normal

Returns: the level set status

Implements bitpit::LevelSetObject.

Definition at line 2446 of file levelSetSegmentationObject.cpp.

◆ fillCellGeometricNarrowBandLocationCache()

LevelSetCellLocation bitpit::LevelSetSegmentationObject::fillCellGeometricNarrowBandLocationCache ( long id )

overrideprotectedvirtual

Fill location cache for the specified cell if it is geometrically inside the narrow band

A cell is geometrically inside the narrow band if its distance from the surface is smaller than the narrow band side or if it intersects the surface.

This function may require the evaluation of some levelset fields. To improve performance, it is important to attempt filling the cache of the evaluated fields. It is then up to the caches to decide if the fields can be cached.

Parameters

[in] id is the cell id

Returns: The cell location of the cache or LevelSetCellLocation::UNKNOWN if the cell location was not identified.

Implements bitpit::LevelSetObject.

Definition at line 2855 of file levelSetSegmentationObject.cpp.

◆ fillCellLocationCache() [1/2]

void bitpit::LevelSetSegmentationObject::fillCellLocationCache ( )

Fill the cache that contains the zone associated to the cells.

A cell can be either in the narrow band or in the bulk. It will be considered inside the narrow band if one of the following conditions holds:

its distance from the surface is less than the narrow band size;
it intersects the zero-levelset iso-surface (intersections are checked using the FAST_GUARANTEE_FALSE criterium);
one of its neighbors intersects the zero-levelset iso-surface.

Implements bitpit::LevelSetObject.

Definition at line 2632 of file levelSetSegmentationObject.cpp.

double bitpit::LevelSetSegmentationObject::getMinSurfaceFeatureSize ( ) const

Get the smallest characteristic size within the triangulation This function is only provided for guarantee backwards compatibility with older versions. It is out of the levelset scope to evaluate the feature size of the surface.

Returns: smallest characteristic size within the triangulation

◆ setSurface() [1/5]

void bitpit::LevelSetSegmentationObject::setSurface	(	const SurfUnstructured *	surface,
		bool	force = false )

Set the surface

Unless explicitly forced, it is not possible to replace an existing surface. Also, when the surface is replaced, the object will not recalculate the levelset on the newly set surface (nor will tell the proxy objects that may depend on the current object to update the levelset values).

The feature angle will be set to the defualt value specified by the constant LevelSetSegmentationSurfaceInfo::DEFAULT_FEATURE_ANGLE.

Parameters

[in]	surface	is the surface that will be set
[in]	force	controls if it is possible to replace an existing surface.

◆ setSurface() [2/5]

void bitpit::LevelSetSegmentationObject::setSurface	(	const SurfUnstructured *	surface,
		double	featureAngle,
		bool	force = false )

Set the surface

Unless explicitly forced, it is not possible to replace an existing surface. Also, when the surface is replaced, the object will not recalculate the levelset on the newly set surface (nor will tell the proxy objects that may depend on the current object to update the levelset values).

Parameters

[in]	surface	is the surface that will be set
[in]	featureAngle	is the angle that is used to identify sharp edges. If the angle between two segments is bigger than this angle, the enclosed edge is considered as a sharp edge
[in]	force	controls if it is possible to replace an existing surface.

◆ setSurface() [3/5]

void bitpit::LevelSetSegmentationObject::setSurface	(	const SurfUnstructured *	surface,
		double	featureAngle,
		LevelSetSurfaceSmoothing	surfaceSmoothing,
		bool	force = false )

Set the surface

Unless explicitly forced, it is not possible to replace an existing surface. Also, when the surface is replaced, the object will not recalculate the levelset on the newly set surface (nor will tell the proxy objects that may depend on the current object to update the levelset values).

Parameters

[in]	surface	is the surface that will be set
[in]	featureAngle	is the angle that is used to identify sharp edges. If the angle between two segments is bigger than this angle, the enclosed edge is considered as a sharp edge
[in]	surfaceSmoothing	is the given surface snoothing order
[in]	force	controls if it is possible to replace an existing surface.

void bitpit::LevelSetSegmentationObject::setSurface	(	std::unique_ptr< const SurfUnstructured > &&	surface,
		bool	force = false )

Set the surface

Unless explicitly forced, it is not possible to replace an existing surface. Also, when the surface is replaced, the object will not recalculate the levelset on the newly set surface (nor will tell the proxy objects that may depend on the current object to update the levelset values).

The feature angle will be set to the defualt value specified by the constant LevelSetSegmentationSurfaceInfo::DEFAULT_FEATURE_ANGLE.

Parameters

[in]	surface	is the surface that will be set
[in]	force	controls if it is possible to replace an existing surface.

Set the surface

Unless explicitly forced, it is not possible to replace an existing surface. Also, when the surface is replaced, the object will not recalculate the levelset on the newly set surface (nor will tell the proxy objects that may depend on the current object to update the levelset values).

Parameters
