Track physics & animation
« on: May 15, 2016, 04:31:41 am »

Easy track definition using a piece of track (link), engine computes the wrapping curve for tracks defined as collection of wheels, with given number of links to use per track.

Was just looking at War Thunder a few days ago and thinking about tank treads in Outerra. Nice to see!

Neat! Is it ready to be implemented or a work in progress? Also, does it pew-pew?

Wait, those are separate track-elements ?

It's implemented in our dev version. Anything can pew-pew using the existing fire() method too.

Yes. We would need something bigger to make it better visible.

So, does this mean that geometry can now be deformed by a spline? If so, that should make guardrails and railroad tracks theoretically possible, right? Or is this system fundamentally different from that one?

It's not a universal system for repeating geometry along a spline yet, but it's heading there. It will enable things like rails, road poles and guards, bridges, tunnels, electrical lines, ropes ...

Simply amazing as with all the updates and previews of new stuff. That's one awesome looking track. You also mentioned ropes, would something like this make pulleys, hanging bridges and stuff of the like possible? I mean, eventually, I know it still needs some work. That would make for an excellent time killer in the current Outerra demo, just playing around with physics is always nice.
I always forget to ask this, sorry if I'm out of the topic, but is the pop-in of small rocks fixable? Not something that would "break it or make it" for me, but it does stand out pretty badly in some cases (this video is a nice example).

It's mostly about the rendering aspect of the ropes, which also need the physics. Bullet has some support for it, but it needs special handling for OT terrain.

The pop-in arrowhead rocks will be fixed, needs a bit different technique than the simple one used for them currently.

Wooooooooooooooooooooooooooooooooooooooo hA!!!!

You have my gratitude and tanks...

Actually is there any way to prevent the grass and terrain from popping up through the tracks? Would it be able to be hidden once the track is in close enough proximity. Soft terrain compression is also something I hope to see.

Also just a tweak, the wheels themselves always seem to move too fast. Appearing to instantly be somewhere else. Not sure how you can correct that but I remember a while ago you stated wheels didn't have any mass yet and dampening wasn't enough. Can't wait to use this!

Will this model be made available in the standard version of the game?

Is a common effect on videos (and even in real life).

I assume the grass will be automatically hidden with the tracks imprinting into terrain, so I'm not going to deal with that now, even though there are other ways how to hide it. Similar to how the rain has to be occluded from cockpits and water from boats.

Current model is a bit unrealistic in that it doesn't go through computing torque for wheels, but directly produces force acting on the hub, and the wheel rotation is computed from that. That computation itself could be extended to emulate also some wheel inertia, though ideally the whole thing would be done properly ...

Not sure if this one, but some tank model is going to be included.

When this will be implemented I think someone(maybe me?) will go on and try to import vehicles from World of Tanks or War Thunder
