Saw one of these on your minus feed a few days ago.. You have been keeping me up nights!
-
Wow looks like the Fractopolis airport has taken a little bit of a beating. :P They look good.
Are these ready enough to be in the next development version? I'm planning on picking up a new video card this weekend, so I should be able to play around with Outerra again.
-
Looks good. Small improvement could be, if possible, to generate some cracked asphalt slices around the edges of the craters to make them a bit more 'rough' and not so perfectly round. But anyway dynamic things are always awesome at game engines of this scale. :)
-
I think you should add a modifier that not only calculates an explosions force but also a trajectory. Say a meteor hits at a 45° angle it would make a teardrop shape and throw the debris in the opposite direction. Would look amazing..
Also my friend brought up a question on if a smaller crater can be formed in a larger one and then I wondered if two craters form next to each other and overlap what is the result?
-
You guys never keep resting from what I see.. ;D ... looks pretty ::)

From what I've read, the impact crater shape is always circular (http://www.scientificamerican.com/article.cfm?id=why-are-impact-craters-al).
"In the case of astronomical impacts, though, the physical shape and direction of approach of the meteorite is insignificant compared with the tremendous kinetic energy that it carries."

They can overlap normally, there are some screens showing it too.

I want to add some explosion effects there before the release.

How dare you cite scientific study.
Effects you say.. Par...ticle.. effects?... you say..
-
Yeah, at least a basic particle effect with solid particles of dirt, later some smoke ...
-
Well, that article says also that the craters may be elliptical if the astoroid comes from a very shallow angle. I have a clear image in my mind of a very elliptical crater on mars. I'll try to find a photo.

Multiple varying-size craters stacked on top of each other:

Tatra go down the HOOOOLE...
-
Cool! Now that you did vertical holes, are you going to do horizontal ones? (that is, tunnels, caves,...) ;)
-

Does that mean you'll be adding some sort of "weapon" to make the craters? It would seem weird if there was an explosion every time you "place" a crater on the terrain, assuming the crater interface is similar to how you place road nodes.

This!

Probably the craters will come with different types of textures and effects... I'm sure Cameni thought of that. :)
----------------------------------------------------------------------------------------------------------------------------------------------------
And about what giucam said with the tunnels and caves... ;D
Cool! Now that you did vertical holes, are you going to do horizontal ones? (that is, tunnels, caves,...) ;)
...
Do you think you may extend this option in to more possibilities :D?Like digging holes in the ground with a shovel but having just 25% of the craters dimension like a slice of pizza for the dimensions of the shovel.. ?Or yeah... select to points of entry on each mountain's side.. and unite to create a tunnel and then... you can go inside it and select parts of the tunnel and scale them + or - ... or modify them in some way... like the roads.Hmmmm... any plans for that? ;D

Well, there's no crater interface, I have a key shortcut for it, and the length of the key press determines the crater diameter, appearing in front of you :)
I guess there will be something to throw in the public version ...

... EOD playing getting near. : P Do you plan some pressure ground effect too ? (nice sonic boom from multiple sources at 2:16 - as i understand they do that kind of stuff by large stacks on purpose to partially limit the explosion effect) ... would be nice to have later some smoke effect interface (smoke type as function from "mushroom" type (horizontal center-pointed intake above ground and around center hi-height material flow) to conical explosions (center top intake and sideways conical material flow)). That would cower different types of explosives just nicely.

P.S.: warzone EOD in vid., most of them mixed whyte small-arms munitions.

Outerra: real-time craters (http://www.youtube.com/watch?v=lRpkj4HXF40#ws)
-
This is beyond amazing. Wow just wow. Can´t wait to see it with explosion effects and particles/smoke in action.
Amazing.
Battlefield what?? ;)
-
Very cool!
One of the things i was thinking while watching: MAKE ME A HUUUGE CRATER!!!!
-
Wow that looks really good! I can see myself being entertained by this for a long time. :) Something that I'm definitely going to do is fire a whole bunch of these at a high altitude and watch from the ground as they hit. Dark blue is the biggest, right? 8)
Also really like the dirt particles that fly up in the air.
-
Amazing 8)
Though, I hope this comes with a reset button of some sort, if that's possible? :S
-
So many people were waiting for that big one.. It never came.
I will just be shooting them strait up.. You know we need a bazooka model to go with this right?
-

Yep... Cameni made it seem pretty Hollywood.That long one in the middle was just so made to be seen as a nuke or something... and the expectations where so high to make a half kilometer crater from it.But yeah... :D it looks pretty promising!
-
It will be much more pretty, when this craters will fill up with water, like a sea, and that water flow off like a river..... ::)
-
Great!!
-
Nice.
Earlier you said "They get created generally under half a second".
I thought OK sometimes up to 500ms+, doesn't sound too good. But in this video craters forms the very next frame, IE
no delay. :) (checked slow-mo).
So I guess it's between 1-33ms (30fps=33ms) for normal craters (like in video) correct me if wrong please.
But is it the mile-big craters that gets 500+ms or what?
-
Well, I optimized it more :)
Basically what I did is that the tiles of the terrain hierarchy that are visible in the moment when the crater is created are updated first. Tiles that are affected by the crater, but are only going to be visible when you move closer or further from the crater, are updated on demand.
For larger craters it may take longer in some circumstances, like when you are quite close to them. During game play it will hardly matter though, since it will likely blow you away anyway, and even if it didn't the occlusion by dust and smoke will hide the crater for quite a long time.
-
Like the particle additions to
The craters. Any plans to em corporate light sources which you would expect to appear on the terrain/objects in such an explosion? What about light sources in general, e.g. From headlights
-
Multiple lights need some additional work in the rendering pipeline, a bit non-trivial in our case, but going there.

This is what I think of Outerra....

That's what I mean. A verry simple test for crater lake and river ;)
On that way the water texture are horrible. ::)

Trololololol... fiords.. :o
They look partially cool :) even with the 'radioactive water' ... but still promising stuff. ;D
-
So, how do we fire the meteor cannon?

Turn on Outerra, when you are in the game (no menus) just press Left Click button of your mouse. More time you keep it pressed the bigger the crater. ;)

Thanks!
I literally stumbled across it 2 minutes ago.. feel so dumb. :-\
-
Can we have that attached to the Apache?

That is some nice crater-bath design. :D
-
I did a crater with a diameter of 800 meters!!!!! holding down the left button for one minute! I think it is the limit because I tried few times holding down the mouse button for 2 and 3 minutes but the diameter of the crater is the same realized with one minute holding :)
to be accurate with the measure I made the explosion over 1KM runway... :D
Fantastic! basically I deleted some island in the Mediterranean sea... :D :D :D
-

It's a spa pool ;)
-
So is it possible to make a rabbit hole to China?
-
No, there's a hot magma inside :)
-
HOW MANY CRATERS DOES IT TAKE TO GET TO THE CENTER OF OUTERRA?!
-
^Good question^
Also, about the lava, that should be added! (Not like minecraft but more natural)
-
It turns out that you cant!
There is a certain depth where you can go. Then it acts like a floor!

If you made them big enough.. You could probably get pretty far.

There it is. ;D
-
I would not try that if i where you ... dont you remember the Kola deep hole experiment ? Hell is waiting there for you !!!!
Siberia Hell sounds (http://www.youtube.com/watch?v=nyXtHeHNldE#ws)
.. Ahh, just kidding. ;D Reality is, they stopped funding it after the fall of CCCP (so they messed up the year too) but ended the research near 2000 at about 13 km depth - a great number of interesting stuff were found out of there :
Дорога в Ад — Самое глубокое отверстие в Земле (12 км) (http://www.youtube.com/watch?v=O-fuhQFSmCM#)
Кольская сверхглубокая. Дорога в ад (2012) (http://www.youtube.com/watch?v=_68Y7IIVD2I#)
Around 11 km a great abundance of precious metals was found, and much much water - (from aqueous anorganic cristalline substances, witch at those temperatures and pressure loose wather out of the crystaline mesh, but cant escape the crust because of the waterproof layer at about 6 km) ... would be interesting to go Antenworld deep minimg for platinum ;) ... doe, not white TNT cratering. :)

Challenge accepted! Wait untill the craters are permanent!

Is there a way of tweaking the crater gun? I want to make it more powrful at shorter mouse holding periods.
