Member Function Documentation

AddPoint()

void MeshCore::MeshPointGrid::AddPoint ( const MeshPoint &  rclPt, unsigned long  ulPtIndex, float  fEpsilon = 0.0f  )

protected

Adds a new point element to the grid structure. rclPt is the geometric point and ulPtIndex the corresponding index in the mesh kernel.

FindElements()

unsigned long MeshCore::MeshPointGrid::FindElements	(	const Base::Vector3f &	rclPoint,
		std::set< unsigned long > &	aulElements
	)		const

Finds all points that lie in the same grid as the point rclPoint.

HasElements()

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

protectedvirtual

Returns the number of stored elements.

Implements MeshCore::MeshGrid.

Pos()

void MeshCore::MeshPointGrid::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.

RebuildGrid()

virtual void MeshCore::MeshPointGrid::RebuildGrid ( void  )

protectedvirtual

Rebuilds the grid structure.

Implements MeshCore::MeshGrid.

Validate() [1/2]

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

virtual

Validates the grid structure and rebuilds it if needed.

Implements MeshCore::MeshGrid.

Validate() [2/2]

virtual void MeshCore::MeshPointGrid::Validate ( void  )

virtual

Validates the grid structure and rebuilds it if needed.

Verify()

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

virtual

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

Implements MeshCore::MeshGrid.
