meshio: add .vtk file reading support #215

Closed hhirtz closed 2 years ago

hhirtz commented 2 years ago

Allow the tooling to read legacy VTK files.

TODO

[x] add compilation flags for the cargo features
[x] use proper a error type for the global parse function
[ ] ~~replace todo panics with errors in the vtk module~~ (I actually would rather leave them so that the format can be implemented incrementally)
[x] update the man pages
[x] update mesh-io-ffi

hhirtz commented 2 years ago

The builds fail because mesh-io-ffi (C bindings for mesh-io) haven't been updated, which I will do when I have the time. Otherwise, this allows for mesh-part, weight-gen and cie to read .vtk files (the legacy ascii format, at least) transparently.
