I've recently started 3d modeling for the first time ever.  I downloaded a free....yes, free animation software ap called Anim8or.  I used it to create a Klingon Battle Cruiser and now I've moved on to another Sci-Fi game called Jovian Chronicals.

The Jovian Chronicals are a mostly realistic sci-fi pen and paper RPG set in the Solay system 200 years from now.  Earth is a plauge ridden cesspool, and all of the inner planets are colonised.  The most powerful colony is the Jovian Confederation.  They live in giant colony cylanders orbiting Jupiter (think Babalon 5).

I re-created their most powerful class of battleship, the Ypres class with Anim8or and added it to Orbiter.

Whered you find the tool? I'd love to make some 3D models :D

Where else?

http://www.anim8or.com/

Download is only 500k.

I highly..... highly suggest you do the tutorials provided on that site.  Save the web page as a whole to your hard drive (you can do that you know).  That way when the site closes down someday, or while you learing you don't need the internet connection running.

It took me a bit to learn, about a day.  I couldn't figure out how to make a simple cube.  It just wasn't intuitive.  If you do the Eggplant tutorial you will find out that it is not about drawing a shape freehand, but but having the software make a polygon shape and then you move the points around to radically change what it once was.

Another shot of my ship as incentive for you to try.  I've only been at this a week I might point out.

My favorite part of the ship.  The Engine flames.  I managed to stretch the Orbiter game program a bit to create a larger flame for the huge ship so it would look Ok.  The flames are only large enough for smaller ships about the size of an airplane, not a 510 meter warship like mine.

I created a little pyramid of flames to simulate a single larger flame.  Here is a pic of them on low thrust so you can see them.

Does that use the glider flight model or have you tweaked the engine performance?  How long does it take to go from Earth to Mars in that mutha?  Is that a rotating artificial gravity section I see?

Nice work so far. :)

Nope, just a simple single stage rocket, though very fuel efficient.  Nothing overly interesting about it other than it's looks.  I can't even launch from the ground, because the engines are accurate to the book, which is only .8 g accleration.

I've only just finished it and took it for one interplanetary trip from Earth to Jupiter (Ganymede specifically).  It took game time 16 months, and in real time about 30 minutes.  Jupiter was in the worst launch window available, about 6 months away.  Jupiter was behind the Earh by about 4 Earth months.  I just launched out of Earth Orbit anyway, and did a manual, seat of the pants slingshot close around the Sun to reach Jupiter.

The grav deck is not animated.  It is a grav deck though.  Rolling the ship works just as well, and seems to be the simplest way to fly such a ship.

Interesting approach to the Jupiter transfer, slingshotting around the sun.  I haven't tried any multi-body transfers like that, just straight from Earth to Mars once.  I'm still trying to figure out the multi-body part of the transfer orbit MFD.

It wasn't a multibody trajectory, as the Sun was the reference of my Transfer MFD, Source was my ship, and the target was Jupiter.

There is no computer assisted aid to do that manuver.  As I said, I just winged it.  In some cases the Transfer MFD just won't produce a trajectory that will intercept the planet your heading towards, and you have to wait months for the Earth to move to a good spot.  That isn't true. If you have enough fuel, you can launch whenever you want.

My ship does.  I wanted to try it from this crummy of a launch window to see if I had the statistics of the ship correct.  I figured that if I ran out of fuel getting to Jupiter from there, then I would need to go back into the ship's configuration file and up the fuel efficiency number.  Turns out I didn't.  I made it with 6% fuel remaining.

What I did was thrust directly at the Sun.  I've found that thrusting towards or away from the body your orbiting tends to shift your whole orbit, but not lose you any forward velocity.  Your giving yourself a whole bunch of vertical velocity.

To visualise the planetary arangement, looking down from the top of the solar system (from Polaris star), Earth was at 9 oclock, Jupiter at 12 oclock, and everthing orbits counter-clockwise.

Because Jupiter is moving, I new I would have to aim for about 11 oclock with my orbit path.   Alot of thrust towards the Sun, with some thrust a smidge behind the sun made my elipse of an orbit extend out to about 11 oclock where I wanted it.  Then some retrograde thrusting to make the intercept lines overlap was all it took.

Hans.

Nope, not multiplayer.  It isn't really even a full blown game.  It is very detailed about physics and gravity, but no combat of any kind, and not much else to do other than fly places and see what is there.  That is what I like about it though.  It is very similar to MicroSoft's old Space simulator.

Its a free download, and has tons of add-ons made by second hand developers on their spare time, including WarBirds/WW2 Online's Roger "Frying Tiger" Long.  The DeltaGlider Mk3 included with the base game was redone by him, and it shows.

 ya'll hurting my brain cells:)

 Cool game though, I just somersault with my Space Shuttle:confused:

Hey.  Common story.  My first shuttle flight went way out into space.....then came straight back down.

I had no idea what instruments did what and the rest.  Even getting to the International Space Station took me a week.  Don't even mention how long it took me to get to Mars.

Got her up and flying.  I had to move parts around to make it lay down in a prone postion, which wasn't too hard.

If you get it to transform into airplane mode for atmospheric flight I'll be impressed. :D
