There are many relevant examples on the VTK examples website - such as [https://lorensen.github.io/VTKExamples/site/Cxx/Modelling/DiscreteMarchingCubes/](https://lorensen.github.io/VTKExamples/site/Cxx/Modelling/DiscreteMarchingCubes/). You may also read the VTK textbook to get familiar with basic VTK features.
