Comparison of image processing software 3

After multiple emails and a Skype talk we finally acquired a trial version of Mimics. According to their representative, the program is mainly focused at medical uses. Most importantly how do bones, implants react to friction and temperature changes.

This got us interested, since this was also rather important in our project: we were using CT scans to determine the break-line positions and in the end also fill up the missing shards with (possibly) other materials. In other words, it would be very interesting to see how different connections between materials would influence the durability of the object. I must add, that this is only a presumption after a talk with their representative and we might not be able to go so deep in the subject due to the time limitations. Yet this could be very interesting as a research subject for future students.

Having only a week of work left till the presentation, we decided to only  check what were the possibilities of the translation (CT-scans to .stl) procedure and if the results could be better than from Avizo.

The interface seemed clear, but more limited to what was offered at the latter program. It seemed actually very similar to already mentioned Seg3D, which is also focused on medical use.

After comparing multiple objects we came to conclusion that this program does not offer better translation. The meshing is coarser and even though the stepping is less visible, so are the break lines.

In conclusion, this program might offer higher possibilities going deep into material interaction(3-matic research), but for simple .stl translations Avizo is still the best option.

P.s. For post processing use MeshLab (open source!): there you can both reduce the fineness of the mesh and smooth it.

As promised a day ago we would keep you posted about our adventures with image processing software. Even though we did not receive the trial version of Mimics, Avizo provided a very pleasing outcome and it also read .dcm files.

The program itself is very user friendly and incorporates visual programming with automatized properties, thus giving  the user just enough freedom to not crash his computer or make the process incomprehensible. In this sense it is very similar to 3Dslicer, yet Avizo has more options and more finesse in the details.

The final result is not yet perfect due to rather clear “stepping” in the final 3D model. This, according to our “informer” from the Industrial design engineering faculty, could be solved with Geomagic. However, now we can clearly state that the plan A mentioned in this post is actually possible.
