Big TV production companies often use expensive commercial products able to apply augmented reality to sport broadcasts.
In this paper, we present a method for simulating several animation effects performed by the audience in the stands,
such as mosaics, little flags and a big-sized flags.
The main goal is to develop a very simple method, using low-cost graphics hardware,
affordable for a not so big company, while achieving visual realism and computational efficiency.
We define a common geometry model for different effects,
a construction process for each effect, and
a common animation process by means of a shader.
The construction process instantiates the geometry model to the characteristics of a particular effect.
The animation process is entirely coded
in GLSL for real-time rendering.
The movement is simulated by means of a
vertex displacement technique,
which uses a noise function to modify the shape of geometry.
