GPU based Monte-Carlo simulation of the
n-field model on the square 512×512 grid
(see also Fig.1 and WebGL 3D instanton).
it is the number of MC iterations per frame.
The linear congruential random number generator is used.
You can watch instantons formation from random spin configuration.

Below different HUE colors are used for different spin phases φ
(spin unit vector has coordinates s = (cos φ ·
sin θ, sin φ · sin θ, cos θ) ).
"Top" spins (θ = 0) are white and "bottom" ones
(θ = π) are black.

Instantons (topological solitons) are looked as color round defects
in these pictures.
