Dear Teem-users,

I'm trying to extract isolines from scalar fields (volume datasets in nrrd or raw format), based on BC-splines using the kernels of teem/nrrd. I am basically looking for a sophisticated extension of marching squares (that uses linear interpolation only).

I took a look at the source code of MACET, AFRONT, and the tutorial of nrrd (although this is for indirect volume rendering) with no luck. I also saw that back in 2006 teem distribution used to have a contours.h library which is no longer supported. Maybe you move this functionality somewhere else? or, is isocontour extraction out of the scope of the current capabilities of teem?

Best regards,
