8,000 particles advected through a continuous 3D vector field. Each particle follows the velocity of an invisible flow — no predetermined paths, just emergent behavior from simple trigonometric functions.
Each frame, every particle's position is updated by a velocity field defined as:
v(x,y,z,t) = { sin(y+t), cos(x+z+t), sin(x+y+t) }
The field is continuous and smooth — small perturbations create the flowing, organic motion you see. The camera orbits gently, and exponential fog creates depth. No physics engine, no forces — just math.
