int[] GetIsosurfTopology(
	int caseId,
	int[] edges
)

Function GetIsosurfTopology ( 
	caseId As Integer,
	edges As Integer()
) As Integer()

array<int>^ GetIsosurfTopology(
	int caseId, 
	array<int>^ edges
)

abstract GetIsosurfTopology : 
        caseId : int * 
        edges : int[] -> int[] 

Parameters

caseId

Type: SystemInt32
the isosurf "marching cube" entry for this cell. This is the value returned by getMarchingCaseId

edges

Type: SystemInt32
The array into which the node indices defining the isosurf topology in this cell are to be stored if its length is large enough; otherwise, a new array is allocated for this purpose. New pairs of node ids are stored into the array, each pair of nodes must correspond to an edge of the cell which is cut by the isosurface. An edge is cut by the isosurface when the two nodes of the edge have different signs. The pair of nodes must be correctly ordered to define a non manifold polygon. When the isosurface part is made up of several polygons, each polygon must be separated by OIV.MeshVizXLM.MxMeshViz.END_LIST . The end of the polygons list must be indicated by a pair of OIV.MeshVizXLM.MxMeshViz.END_LIST .

Return Value

This method is used during isosurface and slice extraction on an unstructured mesh (for instance com.openinventor.meshvizxlm.mapping.nodes.MoMeshPlaneSlice , com.openinventor.meshvizxlm.mapping.nodes.MoMeshIsosurface , com.openinventor.meshvizxlm.extractors.isosurf.MiIsosurfExtractUnstructured ). Static implementations are provided for the most common basic volume cells:

• See com.openinventor.meshvizxlm.extractors.cell.MxHexahedronCellExtract#getIsosurfTopology(int,int[])
• See com.openinventor.meshvizxlm.extractors.cell.MxTetrahedronCellExtract#getIsosurfTopology(int,int[])
• See com.openinventor.meshvizxlm.extractors.cell.MxWedgeCellExtract#getIsosurfTopology(int,int[])
• See com.openinventor.meshvizxlm.extractors.cell.MxPyramidCellExtract#getIsosurfTopology(int,int[])

If the specified array is large enough to contain the number of node indices to be returned, they are returned therein. Otherwise, a new array is allocated.
