Stairways, Keys, and Robots

In spite of holidays looming and exams taking up much of my time, I’ve been working on some models instead of visiting with family like I should be. Not only that, but I’ve also been modeling with 3D printing in mind, so many of them are now at Shapeways! For more info on 3D prints, click on the new IZL Model Shop link up above.

Most of these models were done in a single sitting, though one or two are still works in progress. All were done in 2.49b. There is a model or two that I’ve done in the new 2.5, but… suffice it to say, they aren’t quite ready for daylight yet.

On a personal note, my favorite is the robot head. ;)

Blender 2.5 Alpha

Just a very quick update, the official release of the new Blender Alpha is tomorrow! For those of you who haven’t been following along, 2.5 includes tons of new features and a redesigned GUI!  Go here for more details!

Rigged Pistons in Blender

After following a fantastic tutorial by Jonathan Williamson (no relation) I put together this rough animation of a working piston. All of the modeling, animation, and rendering was done using just Blender.

The end of the piston is parented to an empty, and the empty is parented to the through rod which is connected to the flywheel. The in-out movements of the piston and cylinder are calculated automatically. The only thing animated in the video is the flywheel’s turning along it’s y-axis. I’ve been wanting to play with this for a long time. Next up, a steam engine!

I’ve another video rendering out right now. It’s taking awhile, it’s HD and render time is half an hour or so per frame. Can you say ‘not optimized’? Oh well.

Volumetric Smoke with Blender 2.5

I spent some time in Toledo with one of my closest friends, Nathan, this weekend. Between playing tons of video games and a Windows 7 installation, I finally got around to trying out the newest Blender 2.5 svn, which can be found at GraphicAll. In this specific instance, I started tinkering with the volumetric smoke, a feature that previous versions of Blender have been without. Here’s my very first experience with one of my new favorite functions in Blender.

Many examples of the capabilities of this system can be found online, particularly on youtube and vimeo. The higher you pump the resolution, the more realistic the smoke looks!

That’s about it for this post, but here’s a teaser. For those of you interested in RFID technology, expect a very interesting post mid-December.

Dabbling

Being rather busy here at EMU I haven’t been able to put as much free time as I would like into my 3D work, though that isn’t to say I haven’t been creative. Here are a few items I’ve been working on, all of them for fun and experience.

I’ve a few hours before class, so I’m going to work on getting the forums back to one hundred percent. Look for a new section under the IZL forums; Brainstorming.

Boids Particle Physics Simulation

There’s an extremely well written book, one of my personal favorites, entitled “Prey“. The author, Michael Crichton, passed away not too long ago, but he is the well known author of books such as The Terminal Man, Congo, Timeline, Airframe, and Jurassic Park. His book Prey focuses on nanotechnology and evolution, which, since reading the book, has strongly drawn my attention.

In Blender, the particle physics system lets you simulate and control the movement of many small agents in a physics system. You can make them react to gravity, you can make them explode like sparks off of the end of a gun, or even use them to simulate smoke and fire.

In this instance, I made use of Boids. The boids system is similar to the kind of system referenced in Prey, the agents in the simulation are given a predator/prey relationship. The predators will attack and ‘eat’ the prey. The basics of creating such a system can be found here. After much tweaking and rendering, here is one of the video results of the predator prey interactions.

One last thing. Things had become out of control on the forums, and in the process of resetting it, users and posts were lost. We’ve basically started over, so if you had an account you WILL have to re-register. A clean slate is what was needed though, so here’s hoping things go smoother the second time around.

Cheers!

Service Stations and Air Cannons

Finding myself trapped at a service station for quite literally six hours straight the other day, I spent my time wisely, modeling and sketching with the Discovery Channel on in the background. After about an hours worth of time, I had modeled a fairly detailed, realistic looking air cannon, the design of which I had sketched out a few days prior. The cannon, when built, would be just over a foot and a half long, and is meant to be worn on the top of the forearm. The PVC rail that wraps around the arm is not pressurized, but is connected to the cannon in multiple places to help ward off stress fractures that would otherwise make the cannon unsafe to wear.

This Air cannon took about an hour to model, it's from a concept I sketched a few days prior.
