Detailed Description

Defines a triangle cell of a surface mesh.

Nodes and edges are numbered as following :

                    n2
                    x
                   / \
                  /   \                  edge 0 = 01
                 /     \                 edge 1 = 12
                /       \                edge 2 = 20
               /         \
              /           \
          n0 x-------------x n1

Member Function Documentation

virtual float PbTriangleCell::getArea

(

)

const [virtual]

Gets the area of a cell.

Implements PbCell.

virtual float PbTriangleCell::getLongestEdgeLength

(

)

const [virtual]

Gets the length of the longest edge of the cell.

Implements PbCell.

virtual void PbTriangleCell::getNodesIndexOfEdge	(	int	edge,
		PbArrayOfInt &	nodes_index
	)			const [virtual]

Gets the array of 2 index mesh's nodes that belongs to a given edge of this cell.

(edge must be >=0 and < 3)

Implements PbCell.

virtual void PbTriangleCell::getNodesIndexOfFacet	(	int	facet,
		PbArrayOfInt &	nodes_index
	)			const [virtual]

Gets the array of index mesh's nodes that belongs to a given facet of this cell.

(facet must be == 0).

Implements PbCell.

virtual void PbTriangleCell::getNodesLocalIndexOfEdge	(	int	edge,
		PbArrayOfInt &	nodes_index
	)			const [virtual]

Gets the array of 2 nodes index that belongs to a given edge of this cell.

edge must be >=0 and < 3. Each index is >=0 and < 3

Implements PbCell.

virtual void PbTriangleCell::getNodesLocalIndexOfFacet	(	int	facet,
		PbArrayOfInt &	nodes_index
	)			const [virtual]

facet must be == 0. Each index is >=0 and < 3.

Implements PbCell.

virtual float PbTriangleCell::getVolume

(

)

const [inline, virtual]

Returns always 0.

Implements PbCell.

virtual void PbTriangleCell::getWeight	(	const SbVec3f &	pcoord,
		float *	weight
	)			const [virtual]

Gets the 3 weights of a point defined by its parametric coordinates.

Implements PbCell.

virtual int PbTriangleCell::locatePoint	(	const SbVec3f &	coord,
		float	tolerance,
		SbVec3f &	pcoord
	)			const [virtual]

Returns 1 if the point is inside the cell, 0 otherwise.

Gets also the parametric coordinate of the point and its weights

Implements PbCell.

PbTriangleCell& PbTriangleCell::operator=

(

const PbTriangleCell &

cell

)

Assignment operator.

Reimplemented from PbCell.
