OpenVibe 3D Voxel and Topographic Map

Voxel is an OpenVibe 3D plugin that shows how to display reconstructed brain activity through inverse model and voxel visualizer. It can be tested using demo file voxel-display.xml

Another scenario is the 3D topographic map that uses the interpolating potentials at the surface of the scalp, converting them to colours using a colour scale and mapping them over the surface of the scalp.


Here is an example created with raw data from EPOC. It shows in real-time 2D and 3D Topographic maps, Spectrum, Signal and Matrix Display, and also a Time-frequency map.
