Digital Twins: From Visual Effects to Real-World Applications

For years, I’ve been working on what could be described as a precursor to digital twins in the Visual Effects (VFX) industry. Creating digital assets that look indistinguishable from reality, simulating complex physics in Houdini, and crafting dynamic environments have been integral parts of my career as an FX Artist. These workflows often aim to deliver visually stunning results, but they also require a deep understanding of real-world behavior to create simulations that feel believable.

Now, as I explore the world of industrial digital twins, I see strong parallels between the two domains. While VFX emphasizes aesthetics and storytelling, digital twins prioritize precision and functionality—capturing the real world with exacting detail to support decision-making, optimization, and predictive analysis. Despite these differences in focus, the underlying technologies and workflows share many similarities.

From VFX to Digital Twins: Bridging the Gap

In the VFX industry, creating digital worlds demands expertise in areas that are directly transferable to digital twinning:

  • Realistic Asset Creation:

    Crafting detailed 3D models and environments has been a core part of my work. For example, in my VFX reel, I showcase assets, environments, and physics simulations designed to closely mimic the real world—skills that translate directly into creating accurate digital representations for industrial applications.

  • Physics Simulations:

    Simulating natural phenomena like fluids, particles, and rigid bodies has been central to my work in Houdini. Platforms like NVIDIA Omniverse and Genesis AI use solvers that share a similar foundation, enabling high-accuracy simulation of physical systems. My experience with these solvers has involved creating dynamic, data-driven simulations that require both precision and scalability—qualities that are equally important in digital twins.

  • Procedural Systems and Scalability:

    The ability to create scalable systems is essential in both VFX and digital twins. My work on Nordisk Film’s Procedural City Generator highlights how procedural workflows can generate large-scale, dynamic environments—an approach that could support applications like smart city modeling or infrastructure planning.

  • Tool Development and Collaboration:

    Developing intuitive tools to empower teams has been a rewarding part of my career. In Empowering Artists with Intuitive Crowd Tools, I focused on creating systems that simplify complex simulations. Digital twins similarly require user-friendly interfaces to make advanced simulations accessible to diverse stakeholders.

My Journey into Digital Twins

As industries increasingly adopt digital twins for predictive maintenance, process optimization, and scenario simulation, I see this as an exciting opportunity to bring my expertise to a new domain. My background as an FX Artist equips me with a unique perspective—one that blends technical precision with creative problem-solving.

Currently, I am exploring NVIDIA Omniverse, a cutting-edge platform for building and simulating digital twins. With its support for real-time collaboration, advanced rendering, and AI integration, Omniverse feels like a natural extension of the tools I’ve used in VFX. Its reliance on Universal Scene Description (USD), a format I’ve worked with extensively, further bridges the gap between my past and this new frontier.

In addition to Omniverse, I am delving into Genesis, an open-source generative physics engine designed for general-purpose robotics and embodied AI applications. Genesis offers ultra-fast, high-fidelity simulations of various materials and physical phenomena, aligning closely with my experience in physics-based simulations within Houdini. Its capabilities in generating dynamic 4D worlds from natural language descriptions present intriguing possibilities for creating interactive and realistic digital twins.

Physics simulation has always been a cornerstone of my work, particularly in the realm of Computational Fluid Dynamics (CFD). My academic journey culminated in a thesis dedicated to CFD, and this specialization has been a defining aspect of my career in visual effects. The ability to accurately simulate natural phenomena such as fluid flows, particle dynamics, and rigid body interactions has enabled me to create realistic and compelling visual narratives.

The recent advancements in platforms like NVIDIA Omniverse and Genesis have introduced enhanced functionalities for physics simulations, with a notable emphasis on CFD. NVIDIA’s introduction of the Omniverse Blueprint for real-time computer-aided engineering digital twins exemplifies this progress. This blueprint integrates AI-driven simulations to create interactive workflows, significantly accelerating the design and testing processes for complex systems.

Similarly, Genesis has emerged as a groundbreaking open-source physics engine capable of generating dynamic 4D worlds. Its ultra-fast simulation capabilities and generative data engine facilitate the creation of realistic environments, making it a valuable tool for both robotics and AI applications.

These developments resonate deeply with my expertise in CFD and physics-based simulations. The convergence of my academic background and professional experience with the cutting-edge capabilities of Omniverse and Genesis positions me to effectively leverage these tools in the creation of sophisticated digital twins.

By integrating my CFD proficiency with the advanced functionalities of these platforms, I am poised to contribute to the development of digital twins that not only replicate physical systems with high fidelity but also offer real-time interactivity and predictive insights. This synergy between traditional physics simulation expertise and modern technological advancements underscores the transformative potential of digital twins across various industries.

The Future: Digital Twins as Creative and Analytical Tools

My goal is to harness my VFX experience to contribute to the development of digital twins that are not only precise and functional but also engaging and accessible. Whether it’s creating a virtual representation of a wind turbine to optimize energy output or simulating the dynamics of a smart city to improve infrastructure, I’m excited to bring my skills to projects that blend creativity with cutting-edge technology.

This new focus also aligns with my personal interest in supporting the green transition. Digital twins have enormous potential to optimize resource usage, reduce waste, and enhance sustainability, and I’m eager to be part of these impactful solutions.

Conclusion

Transitioning from VFX to digital twins feels like a natural progression for me. While the goals of the two fields may differ, the skills and technologies they require overlap in meaningful ways. My experience in creating visually plausible simulations, coupled with my recent foray into tools like NVIDIA Omniverse, positions me to make significant contributions in this space.

I look forward to building digital twins that not only replicate the real world with precision but also help industries innovate, optimize, and create a more sustainable future.
