Member Function Documentation

AddFacet()

void MeshCore::MeshFacetGrid::AddFacet ( const MeshGeomFacet &  rclFacet, unsigned long  ulFacetIndex, float  fEpsilon = 0.0f  )

protected

Adds a new facet element to the grid structure. rclFacet is the geometric facet and ulFacetIndex the corresponding index in the mesh kernel. The facet is added to each grid element that intersects the facet.

HasElements()

unsigned long MeshCore::MeshFacetGrid::HasElements ( void  ) const

protectedvirtual

Returns the number of stored elements.

Implements MeshCore::MeshGrid.

Pos()

void MeshCore::MeshFacetGrid::Pos ( const Base::Vector3f &  rclPoint, unsigned long &  rulX, unsigned long &  rulY, unsigned long &  rulZ  ) const

protected

Returns the grid numbers to the given point rclPoint.

PosWithCheck()

void MeshCore::MeshFacetGrid::PosWithCheck ( const Base::Vector3f &  rclPoint, unsigned long &  rulX, unsigned long &  rulY, unsigned long &  rulZ  ) const

protected

Returns the grid numbers to the given point rclPoint.

RebuildGrid()

virtual void MeshCore::MeshFacetGrid::RebuildGrid ( void  )

protectedvirtual

Rebuilds the grid structure.

Implements MeshCore::MeshGrid.

SearchNearestFacetInGrid()

void MeshCore::MeshFacetGrid::SearchNearestFacetInGrid	(	unsigned long	ulX,
		unsigned long	ulY,
		unsigned long	ulZ,
		const Base::Vector3f &	rclPt,
		float &	rfMinDist,
		unsigned long &	rulFacetInd
	)		const

Searches for the nearest facet in a given grid element and returns the facet index and the actual distance.

SearchNearestFacetInHull()

void MeshCore::MeshFacetGrid::SearchNearestFacetInHull	(	unsigned long	ulX,
		unsigned long	ulY,
		unsigned long	ulZ,
		unsigned long	ulDistance,
		const Base::Vector3f &	rclPt,
		unsigned long &	rulFacetInd,
		float &	rfMinDist
	)		const

Does basically the same as the method above unless that grid neighbours up to the order of ulDistance are introduced into the search.

SearchNearestFromPoint() [1/2]

unsigned long MeshCore::MeshFacetGrid::SearchNearestFromPoint

(

const Base::Vector3f &

rclPt

)

const

Searches for the nearest facet from a point.

SearchNearestFromPoint() [2/2]

unsigned long MeshCore::MeshFacetGrid::SearchNearestFromPoint	(	const Base::Vector3f &	rclPt,
		float	fMaxSearchArea
	)		const

Searches for the nearest facet from a point with the maximum search area.

Validate() [1/2]

virtual void MeshCore::MeshFacetGrid::Validate ( const MeshKernel &  rclM )

virtual

Validates the grid structure and rebuilds it if needed.

Implements MeshCore::MeshGrid.

Validate() [2/2]

virtual void MeshCore::MeshFacetGrid::Validate ( void  )

virtual

Validates the grid structure and rebuilds it if needed.

Verify()

virtual bool MeshCore::MeshFacetGrid::Verify ( ) const

virtual

Verifies the grid structure and returns false if inconsistencies are found.

Implements MeshCore::MeshGrid.
