Whereas strolling to highschool 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), situated within the European Alps. Surrounded by alpine and beech timber, 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 might do this, however it sparked his curiosity in computer graphics, he says.

Twenty years later, in 2016, Barbič, a professor of pc science on the University of Southern California, in Los Angeles, made his mark. His Ziva VFX software program system permits for the creation of practical muscle, fats, and pores and skin simulations for 3D digital people and creatures.
The expertise 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 motion pictures 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, obtained a 2025 technical achievement Academy Award. It was a “super honor,” he says, because the award acknowledges applied sciences which have had a big influence on movement image manufacturing.
“Pc graphics and simulation can typically really feel like a specialised technical area,” he says, “however the award confirmed that these concepts have an effect on not simply science but additionally artwork and the way tales are instructed on display screen.
“The digital characters enabled by mathematics change into 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 expertise 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 college instructor, who launched him to pc science. When he was 8 years previous, the college 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 recreation utilizing the BASIC programming language.
The machine got here with a booklet that contained directions on the right way 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’s construction, and I modified the directions.”
Of all of the creatures delivered to life utilizing his expertise, 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 recreation the place gamers guided a snowman alongside a winding street. It shifted unpredictably to the left or proper, and gamers amassed factors by remaining on the street 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 pc science at Carnegie Mellon. It was a serious turning level in his life, he says.
His doctoral analysis targeted on creating simulation strategies for objects that may change their form when an outdoor power is utilized to them, often called “deformable objects.”
That mission formed a lot of his later analysis, he says: “I took an interest 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 pc 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 pc science with movie. He developed Vega FEM, an open-source software program program that allowed folks to animate practical 3D deformable objects. However Vega FEM was slender in scope and never precisely what filmmakers wanted, he says, so he began exploring the right way 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. “Tutorial analysis typically produces stunning algorithms, however it may be tough to make these algorithms usable by artists, engineers, or manufacturing groups. I’ve at all times been all for that bridge: taking rigorous computational strategies and turning them into programs that individuals can truly use.”
In 2011 he attended an Association for Computing Machinery convention introduced 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 motion pictures. 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 learning the method of making visible results and studying what roadblocks existed within the movie trade, he says.
On the time, the expertise to create practical soft-tissue and anatomical simulation for digital characters didn’t exist.
“The visible results trade had reached a degree the place surface-level realism was not sufficient,” Barbič says. “A creature might have stunning pores and skin textures and detailed geometry, but when the bones, muscle tissues, and fats beneath didn’t transfer appropriately, the phantasm would break.
“The issue was particularly tough for creatures and characters that must really feel alive: animals, monsters, fantasy creatures, or digital doubles. Their our bodies could have unfamiliar anatomy, however the viewers nonetheless anticipates them to maneuver in a approach that matches real-world expectations. Muscle groups 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 influence.”
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 tissues, fats, pores and skin, and connective tissue deform, work together with bones, and join, and the way muscle tissues activate. As an alternative of animating solely the skin floor, artists can create a mannequin with underlying muscle tissues, bones, delicate 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 expertise makes use of concepts from computational mechanics, finite factor strategies, numerical optimization, contact dealing with, and pc graphics, Barbič says. Finite factor simulation, a way used to foretell how a product or construction reacts to warmth and different real-world forces, supplies a technique to mannequin deformable supplies volumetrically, not simply as surfaces, he says. The device computes inside elastic forces and solves the equations of movement so the character’s tissues reply plausibly to animation, pose adjustments, muscle activation, and dynamic movement.
However the system needed to be designed for artists, Barbič says. In manufacturing, he says, the aim shouldn’t be solely bodily realism but additionally controllable realism.
“Artists must direct the outcome, iterate, and match the simulation into a bigger animation pipeline,” he says. “So the expertise 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 motion pictures. Of all of the creatures delivered to life utilizing his expertise, he’s significantly enamored with King Kong from 2024’s Godzilla vs. Kong.
“When King Kong is strolling, you’ll be able to see the muscle tissues, 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 means of my software program, so I feel 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 instructional. 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 aim is to create pc fashions of palms that can be utilized to design instruments, medical prosthetics, and robotic palms.
“The hand is an interesting and tough system,” Barbič says. “It comprises many small bones, muscle tissues, tendons, ligaments, pores and skin, fats, and different delicate tissues, all packed right into a compact construction and interacting mechanically in complicated methods.”
He and his group 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 signify the interior buildings of the hand and its motions.
“IEEE lets me place my work not solely on this planet of photographs and animation but additionally on this planet of engineering programs that should be correct, secure, 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 pc 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 group to collect information about how the bones, muscle tissues, and fats transfer with every pose.
The data sets are available for anybody to make use of in their very own research.
“This mission can assist medical medical doctors study extra about how the hand is transferring,” Barbič says. “It’s additionally nice for roboticists to raised perceive how the human hand truly works, so [the movements] could 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 concern 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 neighborhood all for visible computing and computational strategies. You could find his analysis within the IEEE Xplore Digital Library.
“IEEE acknowledges the engineering aspect of pc science,” he says. “My work is commonly introduced as pc graphics, however at its core, additionally it is simulation, mechanics, numerical strategies, haptics, visualization, and software program programs.
“IEEE is a neighborhood the place that broader id is smart. It lets me place my work not solely on this planet of photographs and animation but additionally on this planet of engineering programs that should be correct, secure, interactive, and helpful.”
He believes the group is essential in supporting a wholesome interdisciplinary analysis ecosystem at a worldwide 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 numerous fields, he says.
“My analysis typically lives between classes: It’s mathematical but additionally sensible; visible but additionally mechanical; creative but additionally engineering-driven,” he says. “IEEE is without doubt one of the skilled communities the place that combination is known.”
