u/Nice-Sand-3230

Fluid simulation demo with 1Million particles simulated at 605ms/frame with rtx 2050 laptop gpu.

Built from scratch with opengl and cuda.

Uses cuda-gl interlop.

Final version will be released soon

Eulerian grid-based smoke sim running real-time on the GPU.

What's under the hood:

- Semi-Lagrangian advection

- Gauss-Seidel pressure solve with SOR

- Vorticity confinement + buoyancy

- CUDA/OpenGL interop (zero-copy rendering)

Every kernel handwritten in CUDA. Every equation derived from scratch.
