My whole mission tonight was come up with a realistic looking afterburner. I think the colors still might be a bit off. I was actually using a real picture for reference so it's kinda close I think. It started off pretty rough but I think it came out looking pretty decent. Here's a few SS:

Looks good.

I like the bottom left corner picture. It looks real, and I can almost hear it flying over.


Rob Farley(Posted 2007) [#3]
To be honest I think you'd be better off using a cone mesh with a rough gradient texture from white at the base through yellow and red to the end... Make it jitter with random scaling and maybe add the particles as well... then you won't get the gappy effect you've got there


Rob Farley(Posted 2007) [#4]
Something like this... I know I've got the colours wrong, but you get the idea... The outer cone should probably have a different texture too to give a better halo effect.

t=CreateTexture(256,256)

SetBuffer TextureBuffer(t)

Viewport 0,0,256,256

b=0

For y=0 To 255
	Color r,g,b
	For x=0 To 255
		Rect x,y+(Rand(-15,15)),1,10
	Next
	r=r+3:If r>255 Then r=255:g=g+3
	If g>=255 Then g=255:b=b+2
Next

SetBuffer BackBuffer()

c= CreateCone(16,0)
EntityTexture c,t
EntityFX c,17
EntityBlend c,3
PositionMesh c,0,1,0
EntityAlpha c,.5

c1 = CopyEntity(c)
EntityAlpha c1,.2

cam = CreateCamera()

MoveEntity cam,0,0,-10

TurnEntity c,90,90,0
TurnEntity c1,90,90,0


Repeat
	ScaleEntity c,Rnd(.5,.6),Rnd(2,2.2),Rnd(.5,.6)
	ScaleEntity c1,Rnd(.6,.7),Rnd(3,3.3),Rnd(.6,.7)

	TurnEntity c,0,1,0,True
	TurnEntity c1,0,1,0,True
	RenderWorld
	Flip

I think there needs to be a bit more of a cone haze (like Rob's cone but maybe not quite as opaque) around the rings.

But looks good.


Mortiis(Posted 2007) [#6]
Isn't it too long? Also those particles shoulnd't overlap,
they should blend together. It isn't that hard to create a
afterburner with a particle engine. I suggest devils child's
particle engine which I use.


big10p(Posted 2007) [#7]
then you won't get the gappy effect you've got there
I think after burners do have that gappy/ring appearance, in real life...



Matty(Posted 2007) [#8]
While they really do have that gappy ring effect, noone really expects them too - but Chroma is doing a simulation so maybe he wants to keep them that way?


Rob Farley(Posted 2007) [#9]
Grab this...

And run this...

Again the colours are all wrong... but a flame shaped mesh looks a lot better than a cone!

How's this? Thanks for writing that up Rob it looks pretty sweet. :)

I just put position and strobe lights in also. There is sooo much to do: Landing gear, ground steering, vulcan cannon, bombs, explosions, umm...I need a break!




Rob Farley(Posted 2007) [#11]
That looks really good Chroma.

Just improved my attempt a little more... All the bits and bobs are in the zip

Chroma(Posted 2007) [#12]
Here's another pic. I tossed in an F-15 I found floating around. Man I really need to start making a few high quality models...

All the afterburner and external lights are part of the loaded aircraft file now. Still working on the landing gear physics and steering. It's giving me a hella time!




chwaga(Posted 2007) [#13]
I like that last one!


D4NM4N(Posted 2007) [#14]
That last one looked best so far, almost spot on, although i think it need a bit more blue around the exhaust :)
Afterburners do tend to leave a trail of pulse-like combustion rings, the faster its going the more spaced out. kind of like this:






Blitzplotter(Posted 2007) [#15]
I like the attention to detail, great work.


MGE(Posted 2007) [#16]
Yes, looking very good indeed!
