Detailed Description

Real-time raylib visualisation of the 2-D Navier-Stokes demo.

Render layers (back -> front):

1. Vorticity texture (NxN) – red = +omega (CCW), blue = -omega (CW), black = 0
2. Particle tracers – 3 000 massless particles, white with trail fade
3. HUD – solver stats, fps, controls

Keyboard controls: SPACE pause / resume R reset simulation

• / - increase / decrease substeps per frame [ / ] halve / double visualisation omega scale ESC / Q quit

Command-line: ./ns_demo [N] e.g. ./ns_demo 512 (default 256)
