Continuous rolling using Newton.

Quick question for all Newton users. I'm playing around with the app a bit and discovered that whenever adjusting the roll setting the lead in and lead out is always smoothed such that the next piece of track should practically stay at that particular banking. For example this preview. I'm trying to create a 0 g roll by banking into the section at a pitch, reducing the vertical g?????????s to 0 and creating the next section as the roll itself.



The same goes for trying to create a flat spin. And doesn't get filtered out no matter how intense the smooth settings are adjusted.
Anyone maybe knows if this is possible or am I missing something in this app?

What transition type are you using (Quintic, Bernstein, Agnesi)? That part looks like something you can cover with the bump transition type or the Quintic to slope and slope to quintic.

Bernstein. I tried the whole lot of them and it still gives this effect.

Okay, Newton can't split a transition into two segments unless you are using the quintic to slope and slope to quintic transitions. An other way around it is to just make the transition from the turn into the zero-g-roll in a one segment. Anyway, you should always use the Quintic over Bernstein, at least I've found that it produces more smoother end product. You should just try all the transition types and develop your own way of making a smooth element.

Linear seems to work best for the flat spin element though but it still creates little bumps. I'll try adjusting some stuff here to see if I can get the result flowish. [;)]

This is another example of why I use FVD and not Newton...

Make it continuous. So say like 40????????? - 400????????? for example, then it won't have the little pause. But yeah since Newton can't separate the roll and vertical force times it really can't be done .


Actually you can use a linear transition and just make sure you have the same rate of banking change. Like 180 over 1 second, and then another 90 over .5 seconds, and it will work. That's about the best you can do with Newton.

I have tried this also, and I have found that Newton will scream and whine at you untill you give up. Not possible.

Newton uses the same time zones for G forces AND banking, so I don't that it will be possible to create that correctly. However, the FVD example element (if you just plot an eformula) is a Zero-G roll that would even be easy to customize for people who don't understand how to use it. I would recommend either that or just using a parabola and handbanking it in the editor then AHGing for the desired effect.

Quick at giving up are we?
I'll rather try a thing till I can get a way around it even.[;)]

I'm not sure I understand your issue, but from the sound of the replies, it seems like you are looking for split force/bank timings, but here's a few other comments that come to mind. First, you really should stay away from Bernstein or linear transitions when using banking (quintics are fine). And when smoothing, newton never alters the first and last node in the element. Finally, for 0 g rolls, it's best to use a bump transition for the normal force. This will allow you to create necessary banking and force profiles in a single section, instead of splitting it amongst three.
