Jitter #13

If more than one aircraft are displayed, the other one jumps back and forth from one position to another at a high but visible frequency

Display distance between UAS in UAV3D, jitter should be visible

jtec commented 8 years ago

Seems to be caused by simulink blocks sending UDP packets to UAV3D at different rates.

Set sample rate of all UAV3D interface blocks in simulink to 1/30, moved virtual leader interface block out of triggered navigation subsystem. Remaining issue: when the jme3 update() function is executed, sometimes the aircraft state has not been updated yet, causing jumps as well.

Could the app somehow adapt to the rate of UDP messages and only update the display when messages arrive?

But that would make display quality (framerate) dependent of UDP delays
