Support for 3D isosurfaces from 3D volume data as part of the 3D picture control

I had the need in the past to draw isosurfaces from 3D volume data. My workaround was to export the data in xplor format (see also), then display the isosurfaces using molecular graphics software (such as UCSF Chimera). This is too indirect.

 

The code to do this directly in LabVIEW exists already in the NI Biomedical Startup Kit 3.0. Look under the section "source code":

 

  • Create isosurface from 3D volume data
  • Draw isosurface for 3D picture control
While the full biomedical startup kit requires quite a few extra toolkits to work, these two isosorface tools can work in plain LabVIEW.
My suggestion is to add these two tools (and maybe others?) to the standard 3D picture control palette of LabVIEW.

They are of general interest. 😄
