SVG Slices to Blender Mesh

Postby shaneburke » Thu Nov 15, 2012 4:19 am

Hi All,

I am trying to figure out if there is a way to create a mesh in Blender from a series of SVG paths. I am trying to create an accurate 3D model of the brain, spinal cord, and vasculature to aid in neuroanatomy instruction. Currently, I am tracing each component that I want to highlight from MRI cross sections in Adobe Illustrator and maintaining each component on separate layers, so I will be able to form a separate mesh in blender to isolate important structures.

My Questions:
1) Does blender allow one to import a series of SVGs and create a mesh automatically (I know it's easy to import one path)?
2) If not, is there a way to script in Blender so I can import each SVG path and offset it by a pre-defined amount?
3) Is there a way to connect the SVG slices longitudinally to form a mesh (if it can't be done by Blender automatically)?

Thanks in advance!

Blender can import SVG, so it's also possible to import a whole folder, if not with UI, then with python scripting.

After import, BSurfaces addon should be capable of creating a 3d mesh from your slices:

oh well, BSurfaces should work for outlines, but probably not for your case. I worry you need a special app for medical usage.

Thanks for the quick response. Number 3 in the original post was the problem I was really worried about, but Bsurfaces is exactly what I need! I'll give it a shot over the Thanksgiving break and post my workflow process for everyone's future reference.

I'm actually tracing the components and exporting SVG curves, so no DICOM interpretation is necessary. We're not trying to represent data, but rather create a cinematic fly-through for teaching purposes. The production quality of Blender is what attracted me to it. If anyone needs to represent data, 3DSlicer (http://www.slicer.org) which is maintained by a group at Brigham and Women's hospital is a great tool for that.
