iuri,

the 2D/3D topographic maps simply display a matrix of data over the scalp. The content of this matrix depends on the processing that you perform before the actual visualization box. For example, the scenario that we provide with the OpenViBE release, computes the beta band power on the last second. This is what is displayed in the samples...

Is it clear ?
Best regards,
Yann Renard
