[Insight-users] Visualization of vector field

[Stephen Yip]

Hi Wes,

I don't know if my question makes sense. Ok. Yes, ParaView can open .mhd
file.

But my .mhd file is a vector field. I'd like to open it as a vector field
(arrows) instead of displaying it like a regular image.

Thank you,
Stephen
