Here, i’m looking for shell creation for solid or geometry by passing thickness and dimension of cell as parameter and i need an hollow shell only.
is there any possibilites to acheive this in vtk.js or in some other libraries which i can inprop in vtk,js.
pyvista, trimesh, pymesh these are all tried already.
Python Occt is best way, if there is an solution means.
suggest me if possible in python vtk
help to solve it

VTK.js supports only surface meshes (vtkPolyData). It does not support volumetric meshes. You might want to consider VTK.wasm instead.
