int GetMarchingCaseId(
	bool[] nodesSign,
	long beginNodeId
)

Function GetMarchingCaseId ( 
	nodesSign As Boolean(),
	beginNodeId As Long
) As Integer

int GetMarchingCaseId(
	array<bool>^ nodesSign, 
	long long beginNodeId
)

abstract GetMarchingCaseId : 
        nodesSign : bool[] * 
        beginNodeId : int64 -> int 

Parameters

nodesSign

Type: SystemBoolean
An array containing as many booleans as the number of nodes in the mesh.

Copy

nodesSign[i]

is relative to the sign of the isovalue-i-th node's value.

beginNodeId

Type: SystemInt64
is the first node id used by the mesh topology (see OIV.MeshVizXLM.Mesh.Topology.MiTopologyExplicitI<C>.BeginNodeId .

Return Value

nodesSign[getNodeIndex(i)]

The return entry corresponds to the first argument of GetIsosurfTopology(int, int[]) 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 ).

Note: MeshViz XLM assumes that the cell does not contain any part of an isosurf if and only if the "marching cube" entry equals 0. Thus if all the bits in this word are 1, the method returns 0.
