Original 2-parameter spectrum (bottom); spectrum after compression (Compression ratio = 64) (up)


Original 3-parameter spectrum


Three-parameter spectrum after compression


Capabilities of graphical subsystem: An example of 2-parameter spectrum shown as points with raster


Two-parameter spectrum shown as shaded surface. Shading is done according to the fictive light point


Rectangular view of 2-parameter spectrum displayed in contour mode


Two-parameter spectrum displayed as shaded surface. Shading is proportional to the contents of channels


Two-parameter spectrum in log scale


Another example of 2-parameter spectrum with grid


Two-parameter spectrum shown with shadows


Three-parameter spectrum. The channels are displayed as balls. The position of balls in 3-D space is determined by three parameters and the sizes are proportional to the contents of channels


Three-parameter spectrum with channels shown as shaded balls


Two-dimensional slice in 3-parameter spectrum


Three 1-dimensional slices in 3-parameter spectrum


Three-parameter spectrum shown in isosurface mode. The channels inside of the surface have the contents higher than the given boundary value


Three-parameter spectrum shown as smoothed isosurface (B-spline smoothing)


Three-parameter spectrum displayed as shaded smoothed isosurface


Three-parameter ---ray coincidence spectrum in isosurface mode


Three-parameter ---ray coincidence spectrum shown as volumetric data contours


Another example of three parameter spectrum shown in volumetric display mode


Four-parameter synthetic spectrum. Three-parameters determine the position of the slice in the fourth parameter. The change of contents of channels in this slice is presented by changing the angle and colors in the pies.


Four-parameter experimental spectrum. The change of contents of channels in the forth parameter is represented by changing the ,,radius"


Four-parameter spectrum displayed as isovolume display mode
