I have an object that gets thrown some 10,000 wu. The camera follows it. The object (or maybe its the camera) shakes, like its had too much redbull. Its just a very basic chasecam.
[java]
chasecam = new ChaseCamera(cam, targ, inputManager);
chasecam.setDefaultDistance(300.0f);
chasecam.setMaxDistance(500.0f);
chasecam.setMinDistance(300.0f);
chasecam.setSmoothMotion(false);
chasecam.setTrailingEnabled(false); //only works if smoothMotion is true
//chasecam.setMinVerticalRotation(-1f);
//chasecam.setMaxVerticalRotation(1f);
chasecam.setUpVector(Vector3f.UNIT_Y);[/java]
That kind of behavior happens when float is starting to lose precision. Not much you can do about it except scale distances.
