The application is organised into three panels: control panel, 
models panel, chart panel .
Fig. 4.
 
Control Panel: play button (1), stop button (2), pause button (3), decrease samples per second button (4), samples per 
second label (5), increase samples per second button (6), navigator component (7), previous EEG channel button (8), EEG 
channels combo box (9), next EEG channel button (10), application screen mode button (11)
Control panel is used to play, stop and pause EEG signal, 
change samples per second playing rate, change electrode 
whose signal is drawn on the chart panel and switch between 
full-screen and normal screen mode. Besides that, it contains 
Navigator, which is the component created to navigate the signal 
drawn on the chart panel.

Models panel: models’ scale slider (1), head models (2), scale of colours (3)
ModelsPanel class inherits from PaperBase class, which 
is an extension of Basicview class. Basicview comes from Pa
-
pervision3D library and contains functions and ields essential 
to set up a basic 3D scene. 
To increase usability of the application there are displayed two 
head models. Therefore it was necessary to extend Basicview 
with custom PaperBase class. PaperBase adds additional camera 
and viewport to BasicView and it contains methods that handle 
all interactions with 3D models. Displayed head models are the 
same instance of single model added the stage but rendered 
twice on two viewports and being seen by two cameras that can 
be set at different position in the 3D space.
In order to visualise electrical activity on the model’s scalp, 
proper areas (triangles) were selected with Blender from the 
3D head model and marked as separate objects. Thereby it 
was possible to apply different colour materials to each area 
described by 10-20 international system of electrodes placement.
