## 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 the nature of signal that is being logged. The Y-axis will be the same as the X-axis from that signal and the X-axis will represent the number of logged signal changes (this unit is called ‘change’ in that case).
