To whom it may concern,

Hello my name is Dan Pfeiffer-Kelly a junior mechanical engineering student at Penn State University. I am currently conducting biomechanics and imaging research with one of my professor's (Daniel Cortes). After reading a blog regarding smoothing isosurfaces after segmentation (https://lists.sci.utah.edu/sympa/arc/seg3d/2014-01/msg00002.html),  I wanted to ask a few questions. Any help would be greatly appreciated! 

The primary goal of our research is to develop a multi-scale model of the lower leg. I wont go into all the details, but I have attached to this email a more in depth goals and objectives page if you would like to read it over for any clarifications. Right now I am attempting to segment and generate an isosurface for each muscle in the lower leg. However each muscle must be smooth with no overlap between each isosurface. The primary problem I have come across is I have neither been unable to properly smooth the muscle isosurfaces nor know how to prevent the smoothed surfaces from overlapping. I have tried a few different methods including built in smoothing tools in Seg3D (smooth binary dilate/erode) and exporting an STL file to SketchUp and editing it there. However, none of the methods have produced the results I am looking for. I was wondering if you had any advice? What would be the most practical method to smoothing isosurfaces while still allowing the two surfaces to fit together without overlap or significant gaps? 

After reading over the blog I mentioned above,  the software SCIRun came to my attention. However, I have been having trouble uploading the isosurfaces to SCIRun and using the program in general. I was wondering if you could please clarify how to upload the files to SCIRun and smooth them there? I am unsure if it is just my macbook causing the problem. I plan to try the software on my colleagues PC. I hope to hear back soon and thanks so much for any incite.

Best,

Daniel Pfeiffer-Kelly
