Whereas strolling to high school as a baby, Jernej Barbič would marvel at how stunning his dwelling was. He was born and raised in a picturesque village in northwestern Slovenia (previously Yugoslavia), positioned within the European Alps. Surrounded by alpine and beech bushes, Barbic dreamed of replicating their swaying within the wind for others to get pleasure from.
On the time, he didn’t have the instruments or the data to create a system that would try this, nevertheless it sparked his curiosity in computer graphics, he says.

Twenty years later, in 2016, Barbič, a professor of laptop science on the University of Southern California, in Los Angeles, made his mark. His Ziva VFX software program system permits for the creation of lifelike muscle, fats, and pores and skin simulations for 3D digital people and creatures.
The know-how was launched in 2016 by a startup he helped discovered, Ziva Dynamics, headquartered in Vancouver. It was acquired in 2021 by Unity Technologies of San Francisco.
Ziva VFX has been utilized in greater than 60 films together with Aquaman and the Lost Kingdom; Godzilla x Kong: The New Empire; and Venom: Let There Be Carnage.
For the design and improvement of Ziva VFX, Barbič, an IEEE senior member, acquired a 2025 technical achievement Academy Award. It was a “great honor,” he says, because the award acknowledges applied sciences which have had a major affect on movement image manufacturing.
“Pc graphics and simulation can typically really feel like a specialised technical subject,” he says, “however the award confirmed that these concepts have an effect on not simply science but additionally artwork and the way tales are advised on display.
“The digital characters enabled by mathematics turn out to be essential components of individuals’s lives.”
Barbič says he was impressed to pursue engineering by his father, an engineer who headed a cement manufacturing facility’s analysis division and invented a know-how that makes use of magnetic resonance imaging to check the integrity of cement. His father’s work confirmed him that “arithmetic and physics are stunning on their very own, however engineering permits you to construct one thing that different folks can use,” he says.
It was Barbič’s mom, an elementary faculty trainer, who launched him to laptop science. When he was 8 years outdated, the varsity his mom taught at purchased a ZX Spectrum computer. With permission from the principal, she introduced it dwelling for her son to play on for 2 weeks. However he didn’t simply play video games; he created his personal sport utilizing the BASIC programming language.
The machine got here with a booklet that contained directions on tips on how to write a pc program, he says.
“At first,” he says, “I copied them verbatim with out understanding what they did. However then I began realizing there may be construction, and I modified the directions.”
Of all of the creatures delivered to life utilizing his know-how, Barbič is especially enamored with King Kong from 2024’s Godzilla vs. Kong.DNEG/Warner Bros. Leisure Inc./Legendary
By the top of the 2 weeks, he’d developed a pc sport the place gamers guided a snowman alongside a winding highway. It shifted unpredictably to the left or proper, and gamers accrued factors by remaining on the highway for so long as attainable.
Barbič went on to earn a bachelor’s diploma in arithmetic in 2000 from the University of Ljubljana, in Slovenia. The next 12 months, he moved to the United States to start a doctoral program in laptop science at Carnegie Mellon. It was a serious turning level in his life, he says.
His doctoral analysis targeted on growing simulation strategies for objects that may change their form when an out of doors drive is utilized to them, generally known as “deformable objects.”
That venture formed a lot of his later analysis, he says: “I got interested not solely in making simulations correct but additionally in making them sensible: quick sufficient, sturdy sufficient, and controllable sufficient for use in actual purposes.”
After incomes his Ph.D. in laptop science in 2007, he labored as a postdoctoral researcher at MIT. Two years later, he joined USC as an assistant professor.
Making film magic attainable
It was at USC that Barbič merged his ardour for laptop science with movie. He developed Vega FEM, an open-source software program program that allowed folks to animate lifelike 3D deformable objects. However Vega FEM was slender in scope and never precisely what filmmakers wanted, he says, so he began exploring tips on how to create a model appropriate for the film trade.
“A significant theme of my profession has been the interpretation of analysis concepts into sensible instruments,” he says. “Educational analysis typically produces stunning algorithms, however it may be troublesome to make these algorithms usable by artists, engineers, or manufacturing groups. I’ve at all times been concerned about that bridge: taking rigorous computational strategies and turning them into techniques that individuals can really use.”
In 2011 he attended an Association for Computing Machinery convention offered by its Special Interest Group on Computer Graphics and Interactive Techniques (SIGGraph). There he met James Jacobs, the creature supervisor at visible results firm Weta FX of Wellington, New Zealand. The corporate is behind the results within the Lord of the Rings and Hobbit trilogies and different films. Jacobs used Barbič’s software program to create animals and fantastical creatures.
Two years later, Weta FX supplied Barbič a summerlong research position in New Zealand. He accepted and spent the time finding out the method of making visible results and studying what roadblocks existed within the movie trade, he says.
On the time, the know-how to create lifelike soft-tissue and anatomical simulation for digital characters didn’t exist.
“The visible results trade had reached some extent the place surface-level realism was not sufficient,” Barbič says. “A creature may have stunning pores and skin textures and detailed geometry, but when the bones, muscle mass, and fats beneath didn’t transfer appropriately, the phantasm would break.
“The issue was particularly troublesome for creatures and characters that must really feel alive: animals, monsters, fantasy creatures, or digital doubles. Their our bodies might have unfamiliar anatomy, however the viewers nonetheless anticipates them to maneuver in a method that matches real-world expectations. Muscle mass ought to bulge and contract, pores and skin ought to stretch and slide, fats ought to have inertia, and tissue ought to reply to movement and affect.”
In an effort to unravel the issue Jacobs in 2014 approached Barbič about founding a startup. In 2015 they launched Ziva Dynamics, the place they started what’s now Ziva VFX.
The software program makes use of physics-based simulations to mannequin the interior anatomy of a personality. It numerically solves the partial differential equations of nonlinear elasticity for musculoskeletal human and creature tissues, Barbič says. The equations describe how muscle mass, fats, pores and skin, and connective tissue deform, work together with bones, and join, and the way muscle mass activate. As an alternative of animating solely the skin floor, artists can create a mannequin with underlying muscle mass, bones, mushy tissue, and fats. Every part is assigned materials properties, constraints, attachments, and activations. The simulator then computes how they deform and work together over time.
The know-how makes use of concepts from computational mechanics, finite factor strategies, numerical optimization, contact dealing with, and laptop graphics, Barbič says. Finite factor simulation, a technique used to foretell how a product or construction reacts to warmth and different real-world forces, supplies a solution to mannequin deformable supplies volumetrically, not simply as surfaces, he says. The instrument computes inside elastic forces and solves the equations of movement so the character’s tissues reply plausibly to animation, pose modifications, muscle activation, and dynamic movement.
However the system needed to be designed for artists, Barbič says. In manufacturing, he says, the objective shouldn’t be solely bodily realism but additionally controllable realism.
“Artists must direct the end result, iterate, and match the simulation into a bigger animation pipeline,” he says. “So the know-how needed to mix scientific simulation with sensible controls, robustness, and integration with visible results workflows.”
Barbič says Ziva VFX has been utilized in greater than 60 films. Of all of the creatures delivered to life utilizing his know-how, he’s significantly enamored with King Kong from 2024’s Godzilla vs. Kong.
“When King Kong is strolling, you possibly can see the muscle mass, how they’re very pronounced, and the way they affect the form of the pores and skin. You may actually really feel the power of King Kong,” he says. “And this was made by my software program, so I believe it’s wonderful.”
After Ziva Dynamics was acquired by Unity, Barbič consulted for the corporate for nearly two years.
In 2024 DNEG, a London-based visible results and computer animation firm, acquired the unique license to Ziva VFX.
Animating the human hand
Barbič strives to enhance visible results as an entrepreneur and an educational. His most up-to-date analysis, funded by the U.S. National Science Foundation, targeted on the modeling, simulation, and animation of human palms. The objective is to create laptop fashions of palms that can be utilized to design instruments, medical prosthetics, and robotic palms.
“The hand is an enchanting and troublesome system,” Barbič says. “It incorporates many small bones, muscle mass, tendons, ligaments, pores and skin, fats, and different mushy tissues, all packed right into a compact construction and interacting mechanically in complicated methods.”
He and his staff constructed a digital twin of the human hand.
He aimed to maneuver towards “anatomically significant simulation,” he says. He used medical imaging, geometric modeling, finite factor strategies, and multibody simulation to characterize the interior constructions of the hand and its motions.
“IEEE lets me place my work not solely on the planet of photos and animation but additionally on the planet of engineering techniques that have to be correct, steady, interactive, and helpful.”
He labored with Bohan Wang, who on the time was a USC doctoral candidate, and George Matcuk, an affiliate professor of radiology. Wang is now an assistant professor of laptop science on the National University of Singapore.
Barbič, Wang, and Matcuk scanned 4 folks’s palms with an MRI machine. The 2 males and two girls would place their palms in 12 poses, which allowed the staff to assemble information about how the bones, muscle mass, and fats transfer with every pose.
The data sets are available for anybody to make use of in their very own research.
“This venture may help medical medical doctors be taught extra about how the hand is shifting,” Barbič says. “It’s additionally nice for roboticists to raised perceive how the human hand really works, so [the movements] may be replicated.”
IEEE: Integral in interdisciplinary analysis
Barbič joined IEEE in 2008, when he printed his analysis paper on simulation methods for deformable objects within the inaugural challenge of the IEEE Transactions on Haptics. He has since printed a number of papers within the IEEE Transactions on Visualization and Computer Graphics, which he says linked his work to a wider group concerned about visible computing and computational strategies. You will discover his analysis within the IEEE Xplore Digital Library.
“IEEE acknowledges the engineering aspect of laptop science,” he says. “My work is usually offered as laptop graphics, however at its core, it is usually simulation, mechanics, numerical strategies, haptics, visualization, and software program techniques.
“IEEE is a group the place that broader identification is sensible. It lets me place my work not solely on the planet of photos and animation but additionally on the planet of engineering techniques that have to be correct, steady, interactive, and helpful.”
He believes the group is essential in supporting a wholesome interdisciplinary analysis ecosystem at a world scale—which, he says, is why he has served as an affiliate editor for Transactions on Visualization and Pc Graphics and Transactions on Haptics.
Being a member has made it simpler for Barbič to attach with engineers in several fields, he says.
“My analysis typically lives between classes: It’s mathematical but additionally sensible; visible but additionally mechanical; inventive but additionally engineering-driven,” he says. “IEEE is likely one of the skilled communities the place that combination is known.”
