2015 Siggraph: Workshop, ‘Freezing Time,’ to Turn Animation into 3D Printed Sculptures
While the intent behind many 3D printing endeavors is as serious as saving a life, literally, this is a technology used for myriad and highly creative endeavors, and let’s face it–it’s just an awful lot of fun. And that’s exactly what Eric Haines, of Autodesk, and Andrew Glassner, of the Imaginary Institue, from Real-Time Rendering are counting on having this year at 2015 SIGGRAPH, the five-day interdisciplinary ‘experience,’ that certainly counts 3D printing in as one of the new technologies to be examined and highlighted.
Real-Time will be highlighting the technology in a very unique way this Sunday at ‘Making @ SIGGRAPH’ as they take 2D to a much higher plane, featuring their program that translates animation into 3D printed sculpture. This is a true workshop, entitled ‘Freezing Time,’ with seats for 65-70 participants who will each have access to high speed 3D printers so they can rock out their own 3D sculptures upon learning how to use the T2Z program.
T2Z extracts frames from 2D animation, stacking them to make a 3D sculpture, leaving a cool design behind it in the program showing the transition. The results are pretty fascinating, and you can check out an entire gallery of their designs here.
“The (self-imposed) challenge is to create an interesting, looping animation that also creates a visually-pleasing and printable sculpture,” says Haines. “If you want to hack on this code, it’s the Wobbly animation in T2Z.”
Workshop attendees will benefit from Haines’ latest foray into data translation as it pertains to T2Z. He has been using a variety of tools in experimentation, and the code is free and open source, as well as documented for a quicker, more comprehensive understanding.
Even if you can’t be at the show or the workshop, Haines encourages you to try working with this at the desktop, as well as checking out their animations and working with them.
The evolution of this program came about as Glassner was making a series of looping GIFs. At the same time last year, Haines was involved with 3D printing meetups in Boston, and one of his friends pointed out that objects could be deposited onto a large voxel grid, thus offering a “well-formed model with no geometric singularities, precision proglems, etc.”
“3D printers themselves have limits to precision, so using voxels is a good match,” said Haines.
Andrew was responsible for writing most of the code as they began experimenting, and their program came into being, with animations being used to “define voxels.” One thing led to another and Haines ended up converting data into 3D printed sculpture. The resulting program, T2Z, is much more refined and faster, and Haines points out that you can make your own animations.
“Personally, I find this whole design process entertaining,” says Haines. “In idle moments (or at the dentist) I imagine what might make both an interesting animation and a worthwhile sculpture. It’s a fun way to think about modeling and animation, and one where my intuition doesn’t always pay off. The more I play, the more I learn.”
“So download the thing, install Processing and three little libraries (easy!), and start sliding sliders, pushing buttons, and hacking code! And let us know what you find,” says Haines.
The ‘Freezing Time’ workshop will be this Sunday from 12:15-1:45 PM, at South Hall G – Studio Workstation Area.
