Utility class for triangle cells.
Utility class that provides a static implementation of the MiSurfaceCell's methods in a triangle cell. This class is provided to make easier the creation of a class in the application that implements the MiSurfaceCell
interface for a triangle cell.
The following image shows the nodes numbering used by this class. The weights (see getWeight()), and parametric coordinates (see getIsoParametricCoord()) are defined according to this node numbering.

static 
Computes the iso parametric coordinates of the given point in the given cell with the given geometry.
As computing the iso parametric coordinates of a point needs the coordinates of the cell's nodes, the given triangleCell is assumed to contain 3 nodes.
meshGeometry.getCoord(triangleCell>getNodeIndex(i))for each i in the range [02].
[in]  meshGeometry  The geometry of the mesh. 
[in]  triangleCell  The input cell. 
[in]  point  The input point given in the same space coordinate as meshGeometry. 

static 
Returns the iso parametric coordinates of one of the 3 nodes of a triangle cell.
This static method helps to implement the method MiCell::getIsoParametricCoord().
[in]  nodeIndex  Must be defined in the range [02] 

static 
Gets the longest edge of a triangle cell.

static 
Gets the shortest edge of a triangle cell.

inlinestatic 
Gets the weights of a point defined by its iso parametric coordinates.
This static method helps to implement the method MiCell::getWeight(ipcoord,weights) for a triangle cell.
[in]  ipcoord  The iso parametric coordinates of the input point. The reference space for the iso parametric coordinates is assumed to be [01]. Thus any point inside the cell has iso parametric coordinates in the interval [01]. 
[out]  weights  This method computes the 3 values weights[02]. It assumes the weights vector array has been already allocated. Its size must be set to 3 (at least) before calling this method, using for instance the weights::resize(3)
