Zini in Osirix and Maya

In Fall 2010, Thesis Research on December 26, 2010 at 4:21 pm

So I finally got a good working render from OsiriX and opened it in Maya, and just as I’d thought, it was a mesh mess to an extreme degree.


Maya can’t seem to automatically fix the Nonmanifold Geometry.  Nonmanifold Geometry is, simply put, a mesh that could not exist in the real world. Maya refuses to convert to subdivisions, booleans won’t work and smooth operations can lead to strange results.

There are three different types of nonmanifold Geometry (actually four since lamina faces are technically also nonmanifold):

• Three or more faces share the same edge on an object
• Two or more faces share the same vertex, yet they share no edge
• Two or more adjacent faces have opposite normal directions

I can’t clean they geometry up myself in the state it’s in. Opposite normal directions can’t be seen because I can’t even seen all the faces.
I’m not sure at this point if it can be any other way.  I need to fix the geometry completely if I ever want to print these.  As of right now however, I need to just concentrate on the reconstructions, even if that means creating a 2 dimensionally likeness first for each of the eight subjects in the narrative.  I just have to get the ball rolling.Click on the image below to take you to a link that will then take you to a video of a fly through I put together in OsiriX. There has got to be work around for posting videos to wordpress without having to click, click, click to actually see it.  I’ll work in this friends.

Here are a few screen captures of the OsiriX interface.  It’s pretty intuitive if you’ve ever used a 3D program before, but it does take some processing power. I’ll have to get it onto a computer at Parsons to save myself some headaches.

The visuals of the build are interesting as well. Click on the image below to take you to a link that will then take you to a video to watch OsiriX in action stitching the layer back together.
