👉 The FG fluid, or Fluid Graphics, is a digital rendering technology that simulates the appearance of traditional fluid dynamics, such as water, oil, or smoke, using a combination of algorithms and precomputed textures. Unlike real-time rendering methods that calculate fluid behavior on the fly, FG fluid precomputes the surface normals and displacement fields of a mesh in advance, allowing for highly realistic and detailed fluid simulations with minimal computational cost during runtime. This makes it particularly useful for applications requiring high visual fidelity, such as films, video games, and scientific visualizations, where the fluid dynamics need to be both smooth and computationally efficient.
