Converting brik/nii/gii data to common 3D format like glTF/STL?

[EXP.2086]

Hi,

How to transform brik/nii/gii data to common 3D format like glTF/FBX/STL? To show the 3d brain in PowerPoint 2019.

Thank you,

If it’s a GIFTI/Surface you can use ConvertSurface[/url], which supports PLY and STL (among others). For volumes, it gets more complex, and usually easiest to convert it to a Surface ([url=https://afni.nimh.nih.gov/pub/dist/doc/program_help/IsoSurface.html]IsoSurface) and then use ConvertSurface.
