I'm new and learning. My WIP.

Cool

Are you talking about the stuff on this page

No, a parabolic function is a second order equation of the form:

y = ax^2+bx+c

Where a describes the slope, b describes the phase and c describes the amplitude. I had forgotten all of this but picked it back up pretty quick as a matter of necessity.

The order (x^2) tells you how many times it crosses, or potentially crosses, the x axis. An order three crosses three times.

I use them to get a nice rounding of a nosecone or some other similar type feature.

I'd probably want to program it as a plug-in.

lol, no, I meant isn't that the sdk stuff your looking for on that page.

Sorry, at 5AMish, I'm a bit drawn out and don't think too straight. My day starts at 3PMish and goes until I'm not thinking too clearly. But, getting back to you initial question:

There's more to it. Andy sent me some things and referred me to supercoldmilk.com for the rest.

Here's another small nibble. I work 3x12 so when a work week is in swing, I don't work on my projects. Today is an especially trying time. Bad day, very bad day.

Regardless, this is a wingcone section. I'm working on the lower part of the fuselage and the wings. The wingcone will go between the fuselage and the engine. This actually looks a a bit stubby, but I'll be able to scale as needed as I begin the assembly.

I'm thinking I may do decks as well, but as sideline to fill time when I get tired of programming, but thats for the future.

This craft is supposed to be 45m long, the width is 95% of the length, so that means it's about 42.75m wide. However, I didn't want to work on something that was 45m long and 42.75m wide, so I did my best to scale it to 1/10th of it's design size. Working on such a micro level means that 0.0001 error makes a difference.

I think this made it as unwieldy as working on something the size of a full-sized battleship. However, I think on the next model, I'm going to try working full-size, so a 250m long ship is going be 250m in AC3D (I'd like to take an aside and state that every time I say AC3D, I actually say AC/DC).

Anyway, here is my progress so far. I worked on a side and mirrored real-time to get symmetry. It's still far from done and I need to tweak it a lot before I'm happy with the final appearance. I've included the two pieces I did earlier to show how they fit into the overall picture.

I want to take another aside and say, Andy, great tool you made here. I'm still so very happy it didn't get discarded from lack of customer interest.

Here is a real-time mirrored hull after scaling and positioning sections of it:

I think some tweaking is needed for the nose cone, but I'm wanting to start painting it now. I'm reading Lisa's tutorial now, so I hope it helps.

My weekend is coming up soon. I spent a bit of the past few days trying to conceptualize a sublight propulsion system for my game.

Chemical, aka solid fuel, is out because it's ineffecient. You have to burn tons of it just to get into sapce. However, from my physics studies, I remember them basing rockets on the concept of momentum, p = m*v, leading me to think, what would make an ideal momentum replacement for a solid fuel system...what produces a massive amount of force on a small amount of matter...rail guns.

The idea is that a projectile is propelled via an electrostatic system, rather than expanding gas, so you can get a mass moving at much higher velocities.

A bit of research turned up coil and gauss guns, so I now started looking at a solenoids, superconductors, the Meissner effect, etc.

Hmmm...If I can model gauss or coil drives, so cooool...

Wiggles · 21st August 2007, 11:17 PM

good luck, in order to make something like that to move that much mass, would require something huge. That's why we don't use them. At least last time I heard

One thing you can look into are scramjets.
