Types of 3D graphics |

3D graphics are used to display any function defined by f(x,y) where x and y can be different
domains, like frequency, time,…

There are two types of 3D graphics in *SIGVIEW:*

· __Time FFT__: f(X,Y) is a function of time and frequency. The function value in some (X,Y)
point represents the intensity of the frequency component Y (Hz) in the moment X
(seconds).

· __Tracking changes as 3D graphics __ : f(X,Y) depends
on nature of signal that is being
logged. Y axis will be the same as X axis from that signal and X axis will represent the
number of logged signal changes (this unit is called ‘change’).
