bool IsPointInsideCell(
	MiGeometryI meshGeometry,
	double[] point,
	double[] weights
)

Function IsPointInsideCell ( 
	meshGeometry As MiGeometryI,
	point As Double(),
	weights As Double()
) As Boolean

bool IsPointInsideCell(
	MiGeometryI^ meshGeometry, 
	array<double>^ point, 
	array<double>^ weights
)

abstract IsPointInsideCell : 
        meshGeometry : MiGeometryI * 
        point : float[] * 
        weights : float[] -> bool 

Parameters

meshGeometry

Type: OIV.MeshVizXLM.Mesh.GeometryMiGeometryI
the geometry of the mesh. It is used to retrieve the node coordinates of this cell

point

Type: SystemDouble
coordinates {x,y,z} of point to be checked

weights

Type: SystemDouble
the array into which the weight values are to be stored, it must contain at least as many elements as the number of nodes in this cell.

Return Value

If the point is inside this cell, the specified array is filled with weight values of the point. A weight value (aka shape function) must be given for each node of the cell, see chapter "Properties of shape functions" in the User's Guide for more details.

This method is not used by all extraction classes but it is needed for streamline extraction for example.

Note: For extraction purpose only, it is not necessary to allocate the weight array since extraction classes are optimized such as weight arrays passed to this method are already allocated and large enough to retrieve all the computed weights. Thus the following assignment is then sufficient:

weight[i] = wi
for each i with 0 <= i < getNumNodes
