Writing custom class based on `vtkDataSet`

Thank you for the response,

I assume that you have some sort of surface tessellation that goes along with the x-y points? And that these tessellated cells are triangles or quads that when extruded create 3D wedges or hexes?

Absolutely right. About an hour ago I finally achieved some success (with memory leaks yet of course) and I’m proud to show it

As you said one have to provide XYZ surface grid and Z spacings (double array where all elements are either positive or negative). To visualize with colors o course one need to provide array of values for each cell/point.

FindCell() and FindPoint() are probably some of the trickiest methods.

Does these methods should return the nearest point/cell in the terms of Eigen space like min(sqrt(x1-x0)^2+(y1-y0)^2+(z1-z0)^2) ? For now I have defined these methods with that logic.

I would like to contribute to VTK but not soon as I need to be confident that the project is pretty stable and may be applied in practical tasks.
