At first, hardware circuit of the system has been designed, including minimum system of DSP, sampling pretreatment, dead zone formation, constant amplitude control and display circuit.

Local source data is first sampled at an original sampling rate and then resampled at a first resampling rate which is equal to the framing rate for transmitting said data to the remote source.

For the 3-dimension geometric figures sampling, the first sampling-position was most likely located at the outline parts of the figures, and rarely at the center of gravity of the figures.
