The physics of water
Water has always been a difficult element to reproduce in video games, especially since the advent of 3D. Most developers use a mesh system for their rendering. The advantage of this method is that it requires very little performance, and the rendering remains credible.
In the clip below, Grand Theft Auto V is illustrated entirely in wireframe, showing the water movement mechanism:
For GTA 6,
Rockstar Games has devised a revolutionary system for obtaining physically simulated water in real time. This has been done for years in film and 3D applications, but the rendering has never been «
realtime« .
Experiments have already been carried out at NVIDIA, but the balance between realism and performance has never been sufficiently interesting to be exploitable.
WaveWorks 1.0 offered an improved mesh system that was the cutting edge a few years ago, but was never really exploited:
More recently, WaveWorks 2.0 has made it possible to obtain a partially node-based system, but the result is still a long way from what Rockstar Games has developed:
Rockstar Games has therefore decided to
develop a new technology concerning water physics and integrate it into their next project, GTA 6. The team in charge of this mission is called the «
RAGE Technology Group« , a subdivision of the Rockstar San Diego studio that developed and released the starry firm’s proprietary engine in 2006. The team is composed of twenty-ish engineers with in-depth knowledge of programming, real-time physics simulation, understanding of memory
padding considerations, linear algebra, trigonometry, matrix and quaternion mathematics.
After months of research, experimentation and optimization, engineers at the Californian studio have achieved the feat of
physically simulating water in an open-world video game in real time.
Here’s a 3D animation from 2016 that best represents the physics and graphics of the water we’ll see in GTA 6:
We can therefore speculate that
the ocean will play an important role in the GTA 6 universe, and that new activities such as
surfing will be possible (although this has not yet been confirmed). In 2000, Rockstar Games published the video game
Surfing H30, developed by Opus Studio. The game being what it is, it had the merit of daring to venture into an area where the technical capabilities of the time were not optimal for making the most of the targeted activity.

ach mist, cancelt GTA6, laut
@Fisker ist Wassersimulation doch unwichtig
