MCS
Well, some of you might have noticed I haven't been here much of late.
fx: waves to newbies and recent regulars who might not know/remember me It has been *ages* since I've had any serious involvement here, but work keeps me away for the most part. Recently I've lurked for a bit (to get an idea of who's around and who's moved on, and it's good net practise since I'm coming back to a group almost like a newbie), and now I have a teeny weeny bit of time on my hands, I'm going to stay for a little while... I'm taking a very short sabbatical from MCS (and pretty much everything else) to recover, recuperate and recharge (just a week or three). A lot of effort, late nights, sacrifice, swearing and sweat, but I reckon with everything to hand I'm back on deck and recovered from the hard drive loss, bigger, better and stronger than before. I also have a very interested party who is looking to be involved in a serious way, but details of that won't be looked into until the end of August. To celebrate the return to full-on "GO" mode, I've released the Cinema Sample sequence as seen at TORCON last year. http://www.users.bigpond.net.au/surf...SHomepage.html Go to Gallery, Movie Clips and enjoy (check out updates for more info). I'll be releasing more clips shortly, including the Cinema Sequence in MPG format (it's currently in Quicktime .mov format and Windows Media Player .wmv format) so stay tuned. Cheers everyone, David -- per aspera ad astra |

He was really enthusiastic at NARCON '01 when it was shown there that one night I attended. 2) Ok, spill. *How* is the 30-engine flame sequence done?

Mmmmmm hugs and kisses to you too, sweetheart :-) Two questions come to mind: 1) Has Fred Ordway seen this? He was really enthusiastic at NARCON '01 when it was shown there that one night I attended. I've not communicated with him directly about this clip - he's a bit reticent to open up when it comes to email - just the facts in as few words as permissible. If that's his way then so be it, but it means I can't read what his emotional reactions are to anything that me might have encountered from any of this. 2) Ok, spill. *How* is the 30-engine flame sequence done? Well, I could tell you, but then I'd have to kill you. .... Buggrit - you're gonna die anyway[1], so here goes: 3D model of the tail end of the ferry rocket. In the bells of the engines - but rendered as a separate pass - 3D particle effects, multiple layered with some layers blurred, some sharp, some faint, some strong; and composited for flow (this is the unburnt fuel and fine particles preceding All Hell. Added to that, billowing objects texturemapped and displacement mapped using a fractally based procedural shader, with the objects also keyframed from small to large and teardrop shaped. Added to *that* is a practical pyrotechnic shot in real time and inverted, though the overall shot could certainly survive without this. I use ElectricImage http://www.eitechnologygroup.com for my 3D, and rely on shaders from third party suppliers like Konkeptoine http://www.konkeptoine.com for some of the more freaky and downright brilliant effects. Unlike a lot of CGI artists I recognize the importance and value of using real items where possible, and keeping the need for CGI to a comparative minimum. If I had the budget I might have gone the way of Ron Howard in Apollo 13 and simply used a source of pressurized vapour like a fire extinguisher on a large model to simulate the blast of fuel and flame, but I would also have gone over it with other CG effects as well, as I ended up doing anyway. The shot took me two days to bash out, with another full day for rendering both 2D compositing and 3D effects. [1] One day ... and the good die young, so you've got a bit of a wait on your hands, OM old son ;-P David -- per aspera ad astra |

I suspected you'd merged in a real pyro, as I've yet to see any rendering engine that could produce billows that realistic. Some of the people I've shown it to have always went "damn! He probably melted that model just for that one shot. Good thing he got it right the first time out!" ....One suggestion, tho: if you haven't already done it, you need to include a sound suppression system scene. Which will require more billowing steam clouds out the wazoo at launch, natch. Otherwise, your colleagues here will no doubt ding you for that ommission :-) I use ElectricImage http://www.eitechnologygroup.com for my 3D, ....I know. Which is why I can't ever get a 3DS port of the VBE from you, dammit :-( If I had the budget I might have gone the way of Ron Howard in Apollo 13 and simply used a source of pressurized vapour like a fire extinguisher on a large model to simulate the blast of fuel and flame, but I would also have gone over it with other CG effects as well, as I ended up doing anyway. ....That initial burst of fuel in "Apollo 13" always did bug me, because that was the only thing that just didn't look like it did when I remember watching those camera shots at launch. It was red/orange/yellow billowing almost at point of ignition, and nowhere do I recall something that looked more like something Derek Meddings or Colin Cantwell would have done with freon cans through hoses. For about a millisecton I was expecting to see them cut to Launch Control and see Steve Zodiac with puppet strings at a console :-) OM -- "No ******* ever won a war by dying for | http://www.io.com/~o_m his country.

Well, the real pyro stands out the most on the sides - the closest bit to camera is almost pure 2D/3D fake. Like I said - the shot didn't really need it, but I got lazy and left it in with a shrug and 'couldn't hurt' type of muttering... Some of the people I've shown it to have always went "damn! He probably melted that model just for that one shot.

Which will require more billowing steam clouds out the wazoo at launch, natch. Otherwise, your colleagues here will no doubt ding you for that ommission :-) Oh yes - a shot already exists of water-based acoustic suppression systems running from the LUT, so with the addition of a couple of other shots, I should be okay there. I use ElectricImage http://www.eitechnologygroup.com for my 3D, ...I know. Which is why I can't ever get a 3DS port of the VBE from you, dammit :-( Well, I *can* export .DXF, .OBJ and even .LWO with the version I have. There's a new version just released (5.5 from the existing 5.0.5) which I haven't got yet (pay day from day job isn't until August) which I suspect may have a greater range of export formats supported. ...That initial burst of fuel in "Apollo 13" always did bug me, because that was the only thing that just didn't look like it did when I remember watching those camera shots at launch.

For about a millisecton I was expecting to see them cut to Launch Control and see Steve Zodiac with puppet strings at a console :-) I had a really good look at the F-1s, but it's important to remember this is not an F-1 driven rocket. The ferry rocket (in MCS it's the Saturn-I, and yes, there's a Saturn-II, III, IV, and V) has a giant cluster of engines, each more or less similar in size to the engine that sent the Redstone aloft in RL. Even then, it's not LOX and alcohol or LOX and RP-1 - it's nitric acid and hydrazine, so there's all sorts of differences (plus a little bit of artistic license as I haven't seen everything I need to see from RL to make it bang on). Either way, everyone who's seen it thus far have been satisfied that it's suitably dramatic, effective and tells the story. For film making, you can't ask for more than that in a response ;-) David -- per aspera ad astra |

Oh wow David - fan freakin' tastic! To see all that work come together so beautifully in that sequence was a goosebump experience. You should have heard the folks going troppo as they appeared on screen. Thanks so much for allowing us to be involved in such a fabulous project. The cockpit shot was way worth the drama behind it. Recharge your batteries and then knock'em dead. This baby is going to fly! - Peter |

Those can all be coverted to 3ds, with varying degrees of preservation ofand material properties etc. etc. There's an app designed for use with EI called "Transporter", which is a convert-anything-to-anything sort of thingy. It comes with EI 5.5 (AIUI), so as soon as the day job bucks descend, I'll be upgrading and tooling up regardless.

Email's on the way, Chuck. Took me a while to get to reading stuff, and your email floored me ;-) David -- per aspera ad astra |
