Creating a Submerged Town in CGI for the Series Surface by CGEV

When CGI Dives to the Depths to Create Art

The French studio CGEV has unveiled the secrets behind one of its most atmospheric creations: a completely submerged town for the series Surface. 🌊 This underwater environment, which combines abandonment and ghostly beauty, represents a major technical challenge that the team solved masterfully. By combining detailed 3D modeling, advanced fluid simulations, and digital compositing, they managed to create a believable world that has become another character within the series' narrative.

The creation of this setting required a multidisciplinary approach where every element, from the architecture to the suspended particles, was meticulously designed and calculated. 🏘️ The artists at CGEV modeled complete buildings, streets, and urban details, which they then adapted to appear as if they had been submerged for years, adding erosion, aquatic vegetation, and that characteristic look of abandonment.

An exercise in verisimilitude where water is not just an effect, but the essence of the environment.

The Technical Magic Behind the Immersion

The aquatic element presents the greatest technical challenges. CGEV used complex fluid simulations to recreate the realistic movement of water, its reflections, and the way light behaves beneath the surface. 💡 Volumetric lighting was crucial to convey the feeling of depth, with light rays piercing the water and interacting with objects and suspended particles, creating that ethereal and mysterious effect that defines the series' atmosphere.

The most notable technical aspects of the process include:

  • Detailed architectural modeling of submerged structures.
  • Fluid dynamics simulations for water movement and interaction.
  • Volumetric lighting and realistic refraction calculations.
  • Integration of characters using advanced compositing techniques.

Narrative Integration and Visual Impact

Beyond the technical virtuosity, the true success of this work lies in how the submerged environment contributes to the narrative of Surface. 🎭 Advanced compositing allowed the actors to interact believably with the digital water and town elements, thanks to the use of virtual cameras and match moving techniques. The final result is a setting that not only impresses visually but also amplifies the dramatic and enigmatic tone of the story.

With so much digital water around, the inhabitants of this town should have brought their floaties... though seeing the result, perhaps they preferred to drown in visual details. 😉 A job that demonstrates that sometimes, to create something truly impactful, you have to get in over your head with technical challenges.
