.. _wrap_trimesh:
Wrapping Other Objects
~~~~~~~~~~~~~~~~~~~~~~
You can wrap several other object types using pyvista including:
- `numpy` arrays
- `trimesh.Trimesh` meshes
- VTK objects
This allows for the "best of both worlds" programming special to
Python due to its modularity. If there's some limitation of pyvista
(or trimesh), then you can adapt your scripts to use the best features
of more than one module.
