Banked roads
« on: May 03, 2011, 04:31:37 pm »
Support for banked roads has been added to the engine. The same mechanism will be also necessary to implement support for superelevation on railroad tracks.

A few screenshots:





Here's also a video showing the creation of artificial banked road with editor and a short drive. There are still some bugs introduced as side effects of banked road support, for example some trees near the road are dislocated and appear in the air.




Extreme angles are possible too, although they make the road system somewhat unstable with several defects appearing on the road surface, mainly near the center line.

Very very nice!  I foresee the Texas Motor Speedway being rebuilt in Outerra: The Game's future :D

If Operation Flashpoint came from this-



I cant wait to see what this engine with all the textures and everything fully finished looks like.

what about automatic generating a mound for compensate height difference?

That's what it does, it will dig you a trench or heap a mound before placing the road, or both if it's on slope.

Edit: this bug actually demonstrates it nicely :)

Wow. So close to perfect. Most maps with nice twisty roads have 3d tree's and someone spending hours pouring detail over it and this is still nicer.

Thank god that tatra has a ricer spoiler to add downforce! Just a suggestion it may be time to create another test vehicle. Something more sporty.

Eh, V8 Supercars is more like it.

Well, we could test model importer and vehicle configuration on another vehicle or two, it you've got something that you want to see there and it's legally ok for us to use it, just point us the right direction. We'll have to prepare the app for modding anyway, so we might as well start testing it now.

Its center of gravity is way too low :)

+1 to V8.

Great work, quick question. How easy is it to do proper line markings? I've seen line markings change 3 times in 200 metres on certain roads  (mostly due to sharp corners where it's unsafe to overtake) and it would be nice to do proper line markings. It has to be easier than drawing new roads each time, maybe painting over segments of roads?

Do you know how hard it is to get a 51 frame gif under 10kb at a decent resolution?

Markings are configurable per road node; if you watch the video in 720p and pause it when the editor window is visible, you'll notice there's a combo box for selecting markings that are to be used for the following road segment, up to the next way point. In fact all of the parameters you can see there can be changed per road node, without the need to terminate and start another road type.

The car should be an BMW X6 M - that's fast enough (> 250 km/h), accelerates like hell (0 - 100 km/h in 4.7 sec) and has a 4WD :)

How do you calculate the curvature of the road? Just splines or a combination of real straights, clothoids and circle segments as real roads do?

We are using cubic splines with optional control of tangents at the way points.

That is so cool, so much flexibility and ease of construction... I be there are countless game designers out there green with envy.
