Cucurbita Maxima 2013

I have to admit that having two children under the age of 2 sort of drains my desire to do fanciful holiday crafts.  However, I've set the bar too high for myself, I suppose.  Anyway, this year I decided to do a rendition of Robert Downey Jr. ala Iron Man 3.  I recently got to see the movie for the first time (the reason: two kids under the age of 2) and really enjoyed it.  Actually, I really like all the Iron Man films, so I think this is a fitting tribute.

 The time waster

The time waste-ee

I had to put in a shot of my daughter's pumpkin

Click here for my comprehensive guide on how to do one of these. I think next year I might try carving one of these out with a rotary tool.  No joke.  I would love to know how to make these go faster.

Mark 3 Suit - Grunging it Up

Even though NASA might be shutdown, that doesn't mean that I have to stop working (yet... but that's another story).  In the mean time, I am at home doing some work.  I finally got the chance to take the Mark 3 suit into ZBrush to do some fine detailing:

After I got to putting back in the seams and wrinkles that didn't show up from the laser scan, I went back and created some grunge maps with added dirt and yellowing of the material. I even programmed in some controls for the rig so you could determine the level of dirt and weathering of the suit to fit whatever needs you had.

Now to test it out in an animation.  The rigging on this uses Modo's full body IK system, which doesn't always work out for the best.

Let's hope this shutdown doesn't last too much longer.

NASA: Asteroid Redirect Manned Mission

So for the past few months I have been working hard with the concept analysis team here at NASA JSC, helping them visualize the recently announced asteroid redirect and utilization mission.  It has been quite the brain-opening experience, learning about all that goes into planning a mission of this caliber.

One of the main things that we have been hard at work at here is an animation representing the manned portion of the mission, which is what the JSC team has been focusing on.  This animation was presented at a mission formulation review up at NASA headquarters:

It was very well received, which was good news for us.  We spent a lot of time this go-around making things look realistic and getting everything we could technically accurate.  (We had gotten a lot operationally wrong the first time we did an animation of this mission).

If you're wondering what I personally did in the video, it was pretty much the part from when the two spaceships dock to when they separate.  All of the modeling and animation was done in Modo while we did the compositing. To save render time on some of the less complicated vehicle shots, we wound up using Video CoPilot's Element 3D plugin for After Effects.  It took a lot to set up, especially since it doesn't cast shadows, but we wound up getting it in the end.  We also got to do our own J.J. Abrams-style lens flares for it, which was a nice touch in the end.  We used SonicFire Pro for mixing together the music, which helped out a bunch in the long haul.  It's a handy piece of software that anyone who regularly does videos needs to pick up.

Overall, I am pleased with the results.  It's a good blend of artistic interpretation with real engineering planning behind it.  Here are a few more still images that I created that were used in the review:

AMA Declassified: Mark 3 Surface Suit

Here's another peek into my work.  We recently got connected to the group here at NASA JSC who are working on the Mark 3 surface suit.  We showed them a few things that we could do and they were interested in how that could apply to their work. 

As a bit of a test run, they gave us a 3D laser-scan of the Mark 3 surface suit.  We quickly did a quick texturing and rendering of the raw file, which was well into the millions of polygons.

I am in the process of creating a low-resolution version of the suit, after which I'll project all the details of the high-resolution into a normal map.  It should be a good asset to have, once I finish it.  It certainly will be hard to create a usable rig for the legs, though, looking at the joints in the hips.  I'm still scratching my head about how to tackle that one.

ZBrush - Lunar Surface

I have been meaning to do a lunar surface ZBrush sculpt for work, and I finally got some time to work at home today.  This was knocked out in about three hours.  If I was doing it right, I would have split up the UV map into four or more tiles, but as it currently sits, the final texture maps were around 8192x8192 pixels.

ZBrush 4R6: ZRemesher

I haven't had much free time lately to do 3D stuff on my own at home, but I really wanted to try out a new feature in ZBrush.  The latest release included a tool they have been developing called "ZRemesher."  It essentially uses complex algorithms to analyze the surfaces of your sculpts to create a base mesh that works with the curves.  With the addition of this tool, it makes sculpting that much easier.

I did the above old man in about two hours in ZBrush.  It started off as a Dynamesh sphere where I got it to the proper size.  After that, I drew some curves on the surface to suggest how the polygon flow should be generated, then let ZRemesher do its magic.  I can't complain:

This truly solidifies ZBrush in my mind as a great development tool.  It's great to worry about technical details later and just focus on the creative at first.

AMA Studios: NASA Asteroid Retrieval & Utilization Mission

Something I finally worked on at my job here with NASA got announced to the public, so I can finally talk about it.

For the past three months, I have been working with a team here that is putting together the manned space flight portion of a mission to capture and study an asteroid.  We have been instrumental in helping the team both visualize and communicate their ideas to the rest of the NASA centers.  It is interesting to see how different concepts come together and how different ideas start to form actual missions.

There are a number of inaccuracies with this video, partially due to time constraints, and partially due to us having to fill a hole we see in the animation.  (You should see the stuff we had to cut out!)  However, the idea is there about what NASA has been charged to do.  Now we get to see if Congress approves the budget suggestion given by the administration.

All in all, this has been a very rewarding project and a lot of fun.  When I have more time, I'll go into more depth on what I did specifically that helped speed along the process.  In short, any shot you see that has a crewman or spacesuit in it is one that I either animated or did some compositing work on.

A Weekend Sculpt: Alien Bust

I had a "free" weekend and decided to spend part of it doing some sculpting in ZBrush.  I have been fascinated with this particular alien head shape and decided to do a little bust sculpting.  The tools in the latest version of ZBrush have been particularly useful in helping the artist with getting the topology to work for them.  Dynamesh along with qRemesher were both helpful in making sure that the topology didn't get too squirrely.

Since I haven't been too impressed with ZBrush's rendering capabilities, I used the Decimation Master plugin to export a lower-res version of the bust out.  Shading, lighting, and rendering were all done in Cinema 4D with some post-processing done in Photoshop.  All in all, this was a fun little practice session.

AMA Unclassified, Part 2: Z1 Spacesuit

I wanted to share one more thing that I've been working on that isn't in the SBU (sensitive but unclassified) realm.  One of the things that we haven't had good access to in the past at our company is actual spacesuits to get texture and reference photography from for our 3D models.  Recently we got to go see a pressure test of the Z1 spacesuit, which we wanted for our library of models.

This character was created and rigged in Modo with the textures done in Photoshop.  Hopefully one day I'll be able to take it into ZBrush and do some real sculpting to it, rather than faking it in Photoshop.

This and other fun perks are a few of the reasons why I am enjoying this job immensely.

AMA Unclassified: Some Stuff I've Done at Work

 I haven't been able to blog that much lately about creative 3D stuff because since I started work at AMA, I have been working on 'sensitive but unclassified' material.  Essentially, it's stuff that if I told you what I did, I'd have to kill you... or at least hit you with a wiffle bat.

Anyway, since most of my time at work is taken up with 3D, I haven't done that much at home.  However, there are a few things that I've worked on either as personal learning projects or developing something that might come in handy in the future.  A lot of what I now do would fall under the category of 'generalist' in the 3D world's terms.  That means I do a lot of 3D modeling, texturing, rigging, lighting, animating, rendering, and compositing... which is the whole kit and kaboodle, basically!  (I even do the music and sound effects now...)

One of my learning projects, I actually did this afternoon in After Effects.  My coworker told me about a great tutorial site called Video Copilot, which sells some great plugins for After Effects, but also has plenty of free lessons on how to do certain things in the program.  One of their tutorials inspired me to try something out to get some more practice in After Effects.  I never used it much before, except to composite my 3D frames together.  Anyway, this is what I came up with:

Now, you're probably wondering why I am proud about creating the above footage.  Well, let me first off explain that nothing of what you see in the video was actually captured as video footage.  I started off with two still images:

The Ares rocket on the launch pad at Cape Canaveral

A NASA T-38 chase plane

Pretty odd, huh?  I watched a tutorial where the guys at Video Copilot took a still image of a volcano and turned it into something that looks like it was video footage shot from a helicopter.  Essentially, it involves taking the still image and slowly distorting it from start to finish in the following fashion:

This gives the illusion of parallax and tricks your brain into thinking that the image is actually moving.  There is a lot of cleanup work, however.  For example, because the towers look goofy in the above twisted image, I had to separate them from the background and then clean up the area behind them so that it looks like nothing is there.  (I actually learned a lot about the tools in AE from this little exercise.)

After that, I added the small chase plane with a particle emitter coming out the back to give the sense of exhaust coming out.  I also added subtle things that help you think that it is real like the shaky camera movement, film grain, the spotty lens artifact, lens flares, and even some subtle chromatic aberration.  All in all, I spent some good time making it look pretty, which I probably wouldn't really get to do in a real production.  Most of all, I've learned how easy it is to fake things in 2D rather than creating them totally in 3D.

Another project I like showing off is the Earth-Moon rig I created using Modo:

My desktop background at work

I found some very nice, detailed texture maps on the internet and used them to create a 1/10,000th scale model of the Earth (Modo wouldn't handle the real scale).  The whole purpose of the rig is to be able to quickly adjust the controls so that you can get realistic lighting conditions and scale for whatever Earth-Moon image you might want to create.

There are controls that let you switch out the cloud texture, change the backdrop, change the season, change the time of day (and the dark side of the Earth will automatically light up... pretty cool stuff, if you ask me).  You can even scale up the moon and the sun if you want to go for some artistic license.  It has been a little side project of mine, but it has actually come in handy when someone came in and asked for a to-scale image of the Earth, the Moon and Mars for a presentation.  I just had to whip out that file and I was done within a half hour.

Bottom line: I'm really liking my work.
