[vtkusers] Re: Help on Building Cells

[Amit Joshi]

hi helder,

For vtkPolyData, you can use InsertNextCell in order to regroup points into
cells as you want. Dont forget to call allocate before the first call to
InsertNextCell in order to specify the total number of cells you are going
to generate
About finding neighbours... well there are two methods
1) GetCellNeighbours - you will require to specify the cellId of the cell
you need to find neighbours for ..
2) GetPointCells - specify a point ID and it will return all the cells that
contain the given point.
I hope it helps...

Amit
