Friday 2010-10-29 Dev. update and Discussion

[322Sqn_Dusty]

Foo'bar,

I'm impressed with your railway works and it fits in the new release. I saw the screens with the huffin' and puffin' of the coalers...what kind of damage can they get? Altough it would be a little waste of the nice locs..the 322Sqn and other sqn's shot up the locs and the boilers blew up with a huge cloud....is that possible? If there's a better topic to discuss..please point it out and this will be removed to keep off the pollution of the update topic.

Bullet has mass and it must affect to a plane when it has been shot. So called "law of momentum conservation".
If a plane starts to shoot, then the plane must shake, then the bullet of the next should follow other trajectory.

I can not find any shake in the video and the trajectories of bullets are all the same.

Of course I don't mind that.

Your're right, in case a bullet can penetrate a steam loco boiler hull (about 2 cm of steel tin, wich is in fact armour) wich can have about 16 bar of pressure (for german locos for instance) then it should show a very huge reaction with smoke and steam.

Any questions about railway damage only Oleg can answer. Sorry I can't tell more.

And it's no waste of nice locos. Just press refly and all is fine again

The Hurricane was known to be a very stable fire platform. Moreover the momentum of a 4000 kg plane at 400 km/h is 3 orders of magnitude bigger than that of eight 10g bullet at 2500 km/h ... if you see what I mean.

I think too that's impossible because that would be too much processing power needed.

There are other ways to achieve craters. A basic double pyramid with 6 sides only costs 16 triangles. Inverted, that looks like a hole. Graphic cards of today have a trick called tessellation. If the crater object was marked as an object that would receive tessellation, the card would increase that 16 triangles to 48, fo example. The crater now looks much smoother and the circular hole will have 12 sides.

Now add another trick, normal mapping (Dot3 bump mapping). Simplified, it's a texture, which tells the card to add extra height/thickness to a point on a model. Say white is very high/thick and black is nothing/zero. Lay a black&white noise texture over the crater and you get the inside surface to look like it's just exploded and it's covered with clumps of dirt and sand.

These effects should have little effect on the frame rate, as they can be distance-indexed, so they start to show only when you get closer. Similar to the LoD models aircraft have.

Bump mapping is an optical illusion, normal mapping really adds surface detail.

Left is bump-, right is normal-mapped. Notice the visual edge of the spheres:

I think Oleg said early on in the thread that the shake was simply turned off for the video.

Absolutely agree.
But I couldn't see the light reflection on a instrument moves as a plane moves. I hope to check this out.

And naturally, the trajectories of bullets should not be the same like those in the video because of the shake of a plan when it fires. I hope to check this too.

Burns about 3 sec, and not really any smoke at all.

I guess it is the .303" B. Mk IV incendiary tracer, which was ignited on firing and burned in flight.

I've checked that Oleg mentioned on the shake after I posted.

Sure, of course, but as we agree he didn't and it was obvious he was being sarcastic.
