%% SampleInterpolateValues3D_Animation
% Demonstrates animated 3D brain visualization using the 'animated' flag.
% The animated mode caches distance computations between frames for speed.
%
% See also: SampleInterpolateValues3D

%% Animated sinusoidal activity
% Simulates oscillating channel data rendered in real time.
% The 'animated' flag skips re-drawing the brain mesh and labels after
% the first frame, only updating vertex colors each iteration.
