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.

Jonah Samson, Peeping Tom, 2008

Current photographs from Jonah Samson are on display at G. Gibson Gallery in Seattle. The work is being shown as part of the exhibit, “View Master” along with Lori Nix and Grace Weston. The group show is very strong so be sure to see the gallery website for details.

Grave Digger, 2008

Samson creates dioramas in miniature and photographs the arrangements. The viewer is often the only witness to the moments the artist produces. The audience turns accomplice through their inability to act in the virtual world of “Pleasantville”. We become guilty bystanders helpless to alter events for better or worse.

Giant Octopus, 2008

All of the scenarios put forth in the exhibited series are plausible, save one. “Giant Octopus” (below) could be interpreted as an homage to Ray Harryhausen the special effects legend of “Clash of the Titans” and “The 7th Voyage of Sinbad” fame.

I discovered this great precedent today on a blog called Look Into My Owl.  (Awesome name)  I’m reprint their article here, but you should check out the site yourself, worth the time.
