Status, things left to do:

- fix a complex mapping issue on Burans nose if possible (Chris?)
- animate the parachutes
- add exhaust flames
- describe Burans retrofire maneuver in last leg of the second orbit
- complete the Zenit trajectories
- some fine tuning of Burans orbit

... As you can see, we are getting close to a completed add-on. The most important issue is the zenit trajectories, we still have no idea where they went down. The other stuff are trivialities.

If they went down in Khazakhstan, the difference between the speed of the ship and the sudden drop of the zenits are insane. If they went down somewhere else, there are no possible place exept for the pacific, but that is rather far away - were they able to reach that far? At Buran´s pace the Pacific rim was 15 minutes away, with Mongolia and China in between; politically, the only possible alternative in those days.

Anyone have ANY input on this?

Wow, it's very nice, cannot wait to see it with roaring exhaust flames!
very well done, Runar, appreciated. :wink:
Bye

Andrea :D

Here is the fire. I am unsure if it should have the glow or not. It looks too artificial, but... Opinions?

Don't know if you really care or not, but the first shot above looks to be very much more realistic.
This from a guy who has seen two of the Saturn V lift-off's. :wink:

Surely the glow looks better, but I suggest to improve the flames, making them a bit less "sharp". :wink:

Runar,

personally, I have a bit of a problem with your "pipe smoke clouds" coming out of the rocket above. It looks more like the smoke from a winterly fireplace than a high-pressure rocket exhaust ;-)

As to the flames, they are by far not bright enough for my taste. Also you won't see so many faint stars so close to the flames for simple physics reasons.

Cheers,
Fridger

Perhaps...
The color will change, it needs a yellow tint. And remember that this is a still image of a *very* quick animation! Both in terms of its lifetime and in how it behaves. It does not stand still at all, it shoots up from the launch pad!

Yes, i see that; comparing them to photos, they are too yellow. That is why i am experimenting with giving them white "atmospheres". Perhaps i must make them brighter, too.

As for the stars, that is Celestia, not me :-)

Well it's still a VERY beautiful rendering, and a simply OUT-STANDING effort on
Runar's part here.

Methinks you people criticize too readily... The flames on the first image DO
come closer to the real thing than the second image. There is LOTS of smoke
and a VERY bright glow from the engines themselves. Of course, I've never
seen them from the same perspective as shown above. Have any of you?

Of course, I never know what the Hell I'm talking about either, so you can just
ignore me if you like. :roll:

That's the spirit of "constructive criticism" we have jointly adopted here in CM. It's the weapon to make things better in the end...and that's what we ALL want.

Yes, most of us know the reasons , yet I am suffering from this unphysical effect since years.

Indeed... That is the point of posting this, here. Like your observations, for example - i have never seen a live rocket launch, so you can compare better than me...

It's not my observational experience but rather simple physics considerations.

actio = reactio

as they say ;-) . A pressure that is strong enough to push such a heavy rocket up into the air must be pretty high and "jetty" rather than look like curly "pipe smoke".

Cheers,
Fridger

Ah, but "Curly Pipe Smoke" is EXACTLY what you see from the ground up.

Just FYI...

Fridger,
As for its appearance, i am working to simulate this: http://russian.wunderground.com/data/wx ... ss/127.jpg

... I cannot afford to make it so detailed that it looks like this in still images; actually i did, but then my Celestia became extremely choppy (i was down to 2-3 fps). So, in the current version, i have reduced quality from several thousand instances of smoke to a few hundred - and it runs smoothly. A side-effect is naturally that a still image will not show what the animation hides because it is so quick - the missing definition of single "puffs of smoke" that fills it out...

It is a balancing between pretty graphics and a smoothly running scenario, and in this case (for once), i am going for the "live" experience since that is the subject matter.

When making my customary wallpapers later on, there is always Photoshop ;-)
