Hi Chris
we have c code for doing this but no binary that calls it in the way you need.
This is the code:
int MRISevertSurface(MRI_SURFACE *mris)
{
int v0, fno;
FACE *face;
for (fno = 0; fno &l

dices, no effect.

Hi Chris
this probably means that the triangles aren't constructed according to our
conventions. The ordering in faces is important as the cross-product
Hi Chris
this probably means that the triangles aren't constructed according to our
conventions. The ordering in faces is important as the cross-product of the
legs of each triangle have to point outwards. That's how we define the
surface normal vector field. Sounds like whatever software you
Freesurfer devs,
I have a baffling problem in mris_sphere.
I have generated some surfaces using an external tool that uses VTK. After
converting the surfaces into freesurfer format using a basic format converter,
then adding volume geometry to the surface file using the image used to create
